2.075
- treat SSL_write returning 0 same as previously -1, as suggested by both
  OpenSSL and LibreSSL documentation
- propagate error from SSL_shutdown, but if the shutdown is caused by an outer
  SSL error keep the original error
- small tests fixes
2.074
- add SSL_ciphersuites option for TLS 1.3 ciphers
- no longer use own default for ciphers, instead use system default but disable
  some weak ciphers which might still be enabled on older systems
2.073
- fix behavior and tests for openssl 3.0.1
- fix #110 - prevent internal error warning in some cases
2.072
- add PEM_certs2file and PEM_file2certs in IO::Socket::SSL::Utils based
  on idea by rovo89 in #101
- certs/*.p12 used for testing should now work with OpenSSL 3.0 too #108
- update public suffix database
2.071 2021/05/23
- fix t/nonblock.t race on some systems. Fixes issue #102, maybe #98 too.
2.070 2021/02/26
- changed bugtracker in Makefile.PL to github, away from obsolete rt.cpan.org
2.069 2021/01/22
- IO::Socket::Utils CERT_asHash and CERT_create now support subject and issuer
  with multiple same parts (like multiple OU). In this case an array ref instead
  of a scalar is used as hash value.
  https://github.com/noxxi/p5-io-socket-ssl/issues/95
2.068 2020/03/31
- treat OpenSSL 1.1.1e as broken and refuse to build with it in order to
  prevent follow-up problems in tests and user code
  https://github.com/noxxi/p5-io-socket-ssl/issues/93
  https://github.com/openssl/openssl/issues/11388
  https://github.com/openssl/openssl/issues/11378
- update PublicSuffix with latest data from publicsuffix.org
2.067 2020/02/14
- fix memory leak on incomplete handshake
  https://github.com/noxxi/p5-io-socket-ssl/issues/92
  Thanks to olegwtf
- add support for SSL_MODE_RELEASE_BUFFERS via SSL_mode_release_buffers
  This can decrease memory usage at the costs of more allocations
  https://rt.cpan.org/Ticket/Display.html?id=129463
- more detailed error messages when loading of certificate file failed
  https://github.com/noxxi/p5-io-socket-ssl/issues/89
- fix for ip_in_cn == 6 in verify_hostname scheme
  https://rt.cpan.org/Ticket/Display.html?id=131384
- deal with new MODE_AUTO_RETRY default in OpenSSL 1.1.1
- fix warning when no ecdh support is available
- documentation update regarding use of select and TLS 1.3
- various fixes in documentation
  https://github.com/noxxi/p5-io-socket-ssl/issues/91
  https://github.com/noxxi/p5-io-socket-ssl/issues/90
  https://github.com/noxxi/p5-io-socket-ssl/issues/87
  https://github.com/noxxi/p5-io-socket-ssl/issues/81
- stability fix t/core.t
2.066 2019/03/06
- fix test t/verify_partial_chain.t by using the newly exposed function
  can_partial_chain instead of guessing (wrongly) if the functionality is
  available
2.065 2019/03/05
- make sure that Net::SSLeay::CTX_get0_param is defined before using
  X509_V_FLAG_PARTIAL_CHAIN. Net::SSLeay 1.85 defined only the second with
  LibreSSL 2.7.4 but not the first
  https://rt.cpan.org/Ticket/Display.html?id=128716
- prefer AES for server side cipher default since it is usually
  hardware-accelerated
2.064 2019/03/04
- make algorithm for fingerprint optional, i.e. detect based on length of
  fingerprint - https://rt.cpan.org/Ticket/Display.html?id=127773
- fix t/sessions.t and improve stability of t/verify_hostname.t on windows
- use CTX_set_ecdh_auto when needed (OpenSSL 1.0.2) if explicit curves are set
- update fingerprints for live tests
2.063 2019/03/01
- support for both RSA and ECDSA certificate on same domain
- update PublicSuffix
- Refuse to build if Net::SSLeay is compiled with one version of OpenSSL but
  then linked against another API-incompatible version (ie. more than just the
  patchlevel differs).
2.062 2019/02/24
- Enable X509_V_FLAG_PARTIAL_CHAIN if supported by Net::SSLeay (1.83+) and
  OpenSSL (1.1.0+). This makes leaf certificates or intermediate certificates in
  the trust store be usable as full trust anchors too.
2.061 2019/02/23
- Support for TLS 1.3 session reuse. Needs Net::SSLeay 1.86+.
  Note that the previous (and undocumented) API for the session cache has been
  changed.
- Support for multiple curves, automatic setting of curves and setting of
  supported curves in client. Needs Net::SSLeay 1.86+.
- Enable Post-Handshake-Authentication (TLSv1.3 feature) client-side when
  client certificates are provided. Thanks to jorton[AT]redhat[DOT]com.
  Needs Net::SSLeay 1.86+.
2.060 2018/09/16
- support for TLS 1.3 with OpenSSL 1.1.1 (needs Net::SSLeay 1.86+)
  Thanks to ppisar[AT]redhat.com for major help
  see also https://rt.cpan.org/Ticket/Display.html?id=126899
  TLS 1.3 support is not complete yet for session reuse
2.059 2018/08/15
- fix memleak when CRL are used.
  Thanks to Franz Skale for report and patch
  https://rt.cpan.org/Ticket/Display.html?id=125867
- fix memleak when using stop_SSL and threads, reported by Paul Evans
  https://rt.cpan.org/Ticket/Display.html?id=125867#txn-1797132
2.058 2018/07/19
- fix t/session_ticket.t: it failed with OpenSSL 1.1.* since this version
  expects the extKeyUsage of clientAuth in the client cert also to be allowed
  by the CA if CA uses extKeyUsage
2.057 2018/07/18
- fix memory leak which occurred with explicit stop_SSL in connection with
  non-blocking sockets or timeout - https://rt.cpan.org/Ticket/Display.html?id=125867
  Thanks to Paul Evans for reporting
- fix redefine warnings in case Socket6 is installed but neither IO::Socket::IP
  nor IO::Socket::INET6 - https://rt.cpan.org/Ticket/Display.html?id=124963
- IO::Socket::SSL::Intercept - optional 'serial' argument can be starting number
  or callback to create serial number based on the original certificate
- new function get_session_reused to check if a session got reused
- IO::Socket::SSL::Utils::CERT_asHash: fingerprint_xxx now set to the correct value
2.056 2018/02/19
- Intercept - fix creation of serial number: base it on binary digest instead of
  treating hex fingerprint as binary. Allow use of own serial numbers again.
- t/io-socket-ip.t - skip test if no IPv6 support on system RT#124464
- update PublicSuffix
2.055 2018/02/15
- use SNI also if hostname was given all-uppercase
- Utils::CERT_create - don't add authority key for issuer since Chrome does
  not like this
- Intercept:
  - change behavior of code based cache to better support synchronizing
    within multiprocess/threaded setups
  - don't use counter for serial number but somehow base it on original
    certificate in order to avoid conflicts with reuse of serial numbers
    after restart
- RT#124431 - better support platforms w/o IPv6
- RT#124306 - spelling fixes in documentation
2.054 2018/01/22
- added missing test certificates to MANIFEST
2.053 2018/01/21
- small behavior fixes
  - if SSL_fingerprint is used and matches don't check for OCSP
  - Utils::CERT_create - small fixes to properly specific purpose, ability to
    use predefined complex purpose but disable some features
- update PublicSuffix
- updates for documentation, especially regarding pitfalls with forking or using
  non-blocking sockets. Spelling fixes.
- test fixes and improvements
  - stability improvements for live tests
  - regenerate certificate in certs/ and make sure they are limited to the
    correct purpose. Checkin program used to generate certificates.
  - adjust tests since certificates have changed and some tests used
    certificates intended for client authentication as server certificates,
    which now no longer works
2.052 2017/10/22
- disable NPN support if LibreSSL>=2.6.1 is detected since they've replaced the
  functions with dummies instead of removing NPN completly or setting
  OPENSSL_NO_NEXTPROTONEG
- t/01loadmodule.t shows more output helpful in debugging problems
- update fingerprints for extenal tests
- update documentation to make behavior of syswrite more clear
2.051 2017/09/05
- syswrite: if SSL_write sets SSL_ERROR_SYSCALL but no $! (as seen with
  OpenSSL 1.1.0 on Windows) set $! to EPIPE to propagate a useful error up
  https://github.com/noxxi/p5-io-socket-ssl/issues/62
2.050 2017/08/18
- removed unnecessary settings of SSL_version and SSL_cipher_list from tests
- protocol_version.t can now deal when TLS 1.0 and/or TLS 1.1 are not supported
  as is the case with openssl versions in latest Debian (buster)
2.049 2017/06/12
- fixed problem caused by typo in the context of session cache
  https://github.com/noxxi/p5-io-socket-ssl/issues/60
- update PublicSuffix information from publicsuffix.org
2.048 2017/04/16
- fixed small memory leaks during destruction of socket and context, RT#120643
2.047 2017/02/16
- better fix for problem which 2.046 tried to fix but broke LWP this way
2.046 2017/02/15
- cleanup everything in DESTROY and make sure to start with a fresh %{*self}
  in configure_SSL because it can happen that a GLOB gets used again without
  calling DESTROY (https://github.com/noxxi/p5-io-socket-ssl/issues/56)
2.045 2017/02/13
- fixed memory leak caused by not destroying CREATED_IN_THIS_THREAD for SSL
  objects -> github pull#55
- optimization: don't track SSL objects and CTX in *CREATED_IN_THIS_THREAD
  if perl is compiled w/o thread support
- small fix in t/protocol_version.t to use older versions of Net::SSLeay
  with openssl build w/o SSLv3 support
- when setting SSL_keepSocketOnError to true the socket will not be closed
  on fatal error. This is a modified version of
  https://github.com/noxxi/p5-io-socket-ssl/pull/53/
2.044 2017/01/26
- protect various 'eval'-based capability detections at startup with a localized
  __DIE__ handler. This way dynamically requiring IO::Socket::SSL as done by
  various third party software should cause less problems even if there is a
  global __DIE__ handler which does not properly deal with 'eval'.
2.043 2017/01/06
- make t/session_ticket.t work with OpenSSL 1.1.0. With this version the
  session does not get reused any longer if it was not properly closed which
  is now done using an explicit close by the client which causes a
  proper SSL_shutdown
2.042 2017/01/05
- enable session ticket callback with Net::SSLeay>=1.80
2.041 2017/01/04
- leave session ticket callback off for now until the needed patch is
  included in Net::SSLeay. See
  https://rt.cpan.org/Ticket/Display.html?id=116118#txn-1696146
2.040 2016/12/17
- fix detection of default CA path for OpenSSL 1.1.x
- Utils::CERT_asHash now includes the signature algorithm used
- Utils::CERT_asHash can now deal with large serial numbers
2.039 2016/11/20
- OpenSSL 1.1.0c changed the behavior of SSL_read so that it now returns -1 on
  EOF without proper SSL shutdown. Since it looks like that this behavior will
  be kept at least for 1.1.1+ adapt to the changed API by treating errno=NOERR
  on SSL_ERROR_SYSCALL as EOF.
2.038 2016/09/17
- restrict session ticket callback to Net::SSLeay 1.79+ since version before
  contains bug. Add test for session reuse
- extend SSL fingerprint to pubkey digest, i.e. 'sha1$pub$xxxxxx....'
- fix t/external/ocsp.t to use different server (under my control) to check
  OCSP stapling
2.037 2016/08/22
- fix session cache del_session: it freed the session but did not properly
  remove it from the cache. Further reuse causes crash.
2.036 2016/08/11
- disable OCSP support when Net::SSLeay 1.75..1.77 is used, see RT#116795
2.035 2016/08/11
- fixes for issues introduced in 2.034
  - return with error in configure_SSL if context creation failed. This
    might otherwise result in a segmentation fault later.
  - apply builtin defaults before any (user configurable) global settings
    (i.e. done with set_defaults, set_default_context...) so that builtins
    don't replace user settings
    Thanks to joel[DOT]a[DOT]berger[AT]gmail[DOT]com for reporting
2.034 2016/08/08
- move handling of global SSL arguments into creation of context, so that these
  get also applied when creating a context only.
2.033 2016/07/15
- support for session ticket reuse over multiple contexts and processes
  (if supported by Net::SSLeay)
- small optimizations, like saving various Net::SSLeay constants into variables
  and access variables instead of calling the constant sub all the time
- make t/dhe.t work with openssl 1.1.0
2.032 2016/07/12
- Set session id context only on the server side. Even if the documentation for
  SSL_CTX_set_session_id_context makes clear that this function is server side
  only it actually affects hndling of session reuse on the client side too and
  can result in error "SSL3_GET_SERVER_HELLO:attempt to reuse session in
  different context" at the client.
2.031 2016/07/08
- fix for bug in session handling introduced in 2.031, RT#115975
  Thanks to paul[AT]city-fan[DOT]org for reporting
2.030 2016/07/08
- Utils::CERT_create - don't add given extensions again if they were already
  added. Firefox croaks with sec_error_extension_value_invalid if (specific?)
  extensions are given twice.
- assume that Net::SSLeay::P_PKCS12_load_file will return the CA certificates
  with the reverse order as in the PKCS12 file, because that's what it does.
- support for creating ECC keys in Utils once supported by Net::SSLeay
- remove internal sub session_cache and access cache directly (faster)
2.029 2016/06/26
- fix del_session method in case a single item was in the cache
- use SSL_session_key as the real key for the cache and not some derivative of
  it, so that it works to remove the entry using the same key
2.028 2016/06/26
- add del_session method to session cache
2.027 2016/04/20
- only added Changes for 2.026
2.026 2016/04/20
- update default server and client ciphers based on recommendation of
  Mozilla and what the current browsers use. Notably this finally disables
  RC4 for the client (was disabled for server long ago) and adds CHACHA20.
2.025 2016/04/04
- Resolved memleak if SSL_crl_file was used: RT#113257, RT#113530
  Thanks to avi[DOT]maslati[AT]forescout[DOT]com and
  mark[DOT]kurman[AT]gmail[DOT]com for reporting the problem
2.024 2016/02/06
- Work around issue where the connect fails on systems having only a loopback
  interface and where IO::Socket::IP is used as super class (default when
  available). Since IO::Socket::IP sets AI_ADDRCONFIG by default connect to
  localhost would fail on this systems. This happened at least for the tests,
  see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=813796
  Workaround is to explicitly set GetAddrInfoFlags to 0 if no GetAddrInfoFlags
  is set but the Family/Domain is given. In this case AI_ADDRCONFIG would not
  be useful anyway but would cause at most harm.
2.023 2016/01/30
- OpenSSL 1.0.2f changed the behavior of SSL shutdown in case the TLS connection
  was not fully established (commit: f73c737c7ac908c5d6407c419769123392a3b0a9).
  This somehow resulted in Net::SSLeay::shutdown returning 0 (i.e. keep trying)
  which caused an endless loop. It will now ignore this result in case the TLS
  connection was not yet established and consider the TLS connection closed
  instead.
2.022 2015/12/10
- fix stringification of IPv6 inside subjectAltNames in Utils::CERT_asHash.
  Thanks to Mark.Martinec[AT]ijs[DOT]si for reporting in #110253
2.021 2015/12/02
- Fixes for documentation and typos thanks to DavsX and jwilk.
- Update PublicSuffix with latest version from publicsuffix.org
2.020 2015/09/20
- support multiple directories in SSL_ca_path as proposed in RT#106711
  by dr1027[AT]evocat[DOT]ne. Directories can be given as array or as string
  with a path separator, see documentation.
- typos fixed thanks to jwilk https://github.com/noxxi/p5-io-socket-ssl/pull/34
2.019 2015/09/01
- work around different behavior of getnameinfo from Socket and Socket6 by
  using a different wrapper depending on which module I use for IPv6.
  Thanks to bluhm for reporting.
2.018 2015/08/27
- RT#106687 - startssl.t failed on darwin with old openssl since server
  requested client certificate but offered also anon ciphers
2.017 2015/08/24
- checks for readability of files/dirs for certificates and CA no longer use
  -r because this is not safe when ACLs are used. Thanks to BBYRD, RT#106295
- new method sock_certificate similar to peer_certificate based on idea of
  Paul Evans, RT#105733
- get_fingerprint can now take optional certificate as argument and compute
  the fingerprint of it. Useful in connection with sock_certificate.
- check for both EWOULDBLOCK and EAGAIN since these codes are different on
  some platforms. Thanks to Andy Grundman, RT#106573
- enforce default verification scheme if none was specified, i.e. no longer
  just warn but accept. If really no verification is wanted a scheme of
  'none' must be explicitly specified.
- support different cipher suites per SNI hosts
2.016 2015/06/02
- add flag X509_V_FLAG_TRUSTED_FIRST by default if available in OpenSSL
  (since 1.02) and available with Net::SSLeay. RT#104759 (thanks GAAS)
- work around hanging prompt() with older perl in Makefile.PL RT#104731
- make t/memleak_bad_handshake.t work on cygwin and other systems having
  /proc/pid/statm, see RT#104659
- add better debugging based on patch from H.Merijn Brand
2.015 2015/05/13
- work around problem with IO::Socket::INET6 on windows, by explicitly using
  Domain AF_INET in the tests.
  Fixes RT#104226 reported by CHORNY
2.014 2015/05/05
- Utils::CERT_create - work around problems with authorityInfoAccess, where
  OpenSSL i2v does not create the same string as v2i expects
- Intercept - don't clone some specific extensions which make only sense with
  the original certificate
2.013 2015/05/01
- assign severities to internal error handling and make sure that follow-up
  errors like "configuration failed" or "certificate verify error" don't
  replace more specific "hostname verification failed" when reporting in
  sub errstr/$SSL_ERROR. see also RT#103423
- enhanced documentation thanks to Chase Whitener
  https://github.com/noxxi/p5-io-socket-ssl/pull/26
2.012 2015/02/02
- fix t/ocsp.t in case no HTTP::Tiny is installed
2.011 2015/02/01
- fix t/ocsp.t - don't count on revoked.grc.com using OCSP stapling #101855
- added option 'purpose' to Utils::CERT_create to get better control of the
  certificates purpose. Default is 'server,client' for non-CA (contrary to
  only 'server' before)
- removed RC4 from default cipher suites on the server site
  https://github.com/noxxi/p5-io-socket-ssl/issues/22
- refactoring of some tests using Test::More thanks to Sweet-kid and the
  2015 Pull Request Challenge
2.010 2015/01/14
- new options SSL_client_ca_file and SSL_client_ca to let the server send
  the list of acceptable CAs for the client certificate.
- t/protocol_version.t - fix in case SSLv3 is not supported in Net::SSLeay.
  RT#101485, thanks to TEAM.
2.009 2015/01/12
- remove util/analyze.pl. This tool is now together with other SSL tools in
  https://github.com/noxxi/p5-ssl-tools
- added ALPN support (needs OpenSSL1.02, Net::SSLeay 1.56+) thanks to TEAM,
  RT#101452
2.008 2014/12/16
- work around recent OCSP verification errors for revoked.grc.com (badly signed
  OCSP response, Firefox also complains about it) in test t/external/ocsp.t.
- util/analyze.pl - report more details about preferred cipher for specific TLS
  versions
2.007 2014/11/26
- make getline/readline fall back to super class if class is not sslified yet,
  i.e. behave the same as sysread, syswrite etc.
  This fixes RT#100529
2.006 2014/11/22
- Make (hopefully) non-blocking work on windows by using EWOULDBLOCK instead of
  EAGAIN. While this is the same on UNIX it is different on Windows and socket
  operations return there (WSA)EWOULDBLOCK and not EAGAIN. Enable non-blocking
  tests on Windows too.
- make PublicSuffix::_default_data thread safe
- update PublicSuffix with latest list from publicsuffix.org
2.005 2014/11/15
- next try to fix t/protocol_version.t for OpenSSL w/o SSLv3 support
2.004 2014/11/15
- only test fix: fix t/protocol_version.t to deal with OpenSSL installations
  which are compiled without SSLv3 support.
2.003 2014/11/14
- make SSLv3 available even if the SSL library disables it by default in
  SSL_CTX_new (like done in LibreSSL). Default will stay to disable SSLv3,
  so this will be only done when setting SSL_version explicitly.
- fix possible segmentation fault when trying to use an invalid certificate,
  reported by Nick Andrew.
- Use only the ICANN part of the default public suffix list and not the
  private domains. This makes existing exceptions for s3.amazonaws.com and
  googleapis.com obsolete. Thanks to Gervase Markham from mozilla.org.
2.002 2014/10/21
- fix check for (invalid) IPv4 when validating hostname against certificate. Do
  not use inet_aton any longer because it can cause DNS lookups for malformed
  IP. RT#99448, thanks to justincase[AT]yopmail[DOT]com.
- Update PublicSuffix with latest version from publicsuffix.org - lots of new
  top level domains.
- Add exception to PublicSuffix for s3.amazonaws.com - RT#99702, thanks to
  cpan[AT]cpanel[DOT]net.
2.001 2014/10/21
- Add SSL_OP_SINGLE_(DH|ECDH)_USE to default options to increase PFS security.
  Thanks to Heikki Vatiainen for suggesting.
- Update external tests with currently expected fingerprints of hosts.
- Some fixes to make it still work on 5.8.1.
2.000 2014/10/15
- consider SSL3.0 as broken because of POODLE and disable it by default.
- Skip live tests without asking if environment NO_NETWORK_TESTING is set.
  Thanks to ntyni[AT]debian[DOT]org for suggestion.
- skip tests which require fork on non-default windows setups without proper
  fork. Thanks to SHAY for https://github.com/noxxi/p5-io-socket-ssl/pull/18
1.999 2014/10/09
- make sure we don't use version 0.30 of IO::Socket::IP
- make sure that PeerHost is checked on all places where PeerAddr is
  checked, because these are synonyms and IO::Socket::IP prefers PeerHost
  while others prefer PeerAddr. Also accept PeerService additionally to
  PeerPort.
  See https://github.com/noxxi/p5-io-socket-ssl/issues/16 for details.
- add ability to use client certificates and to overwrite hostname with
  util/analyze-ssl.pl.
1.998 2014/09/07
- make client authentication work at the server side when SNI is in by use
  having CA path and other settings in all SSL contexts instead of only the main
  one.  Based on code from lundstrom[DOT]jerry[AT]gmail[DOT]com,
  https://github.com/noxxi/p5-io-socket-ssl/pull/15
1.997 2014/07/12
- thanks to return code 1 from Net::SSLeay::library_init if the library needed
  initialization and 0 if not we can now clearly distinguish if initialization
  was needed and do not need any work-arounds for perlcc by the user.
1.996 2014/07/12
- move initialization of OpenSSL-internals out of INIT again because this
  breaks if module is used with require. Since there is no right place to
  work in all circumstances just document the work-arounds needed for
  perlcc. RT#97166
1.995 2014/07/11
- RT#95452 - move initialization and creation of OpenSSL-internals into INIT
  section, so they get executed after compilation and perlcc is happy.
- refresh option for peer_certificate, so that it checks if the certificate
  changed in the mean time (on renegotiation)
- fix fingerprint checking - now applies only to topmost certificate
- IO::Socket::SSL::Utils - accept extensions within CERT_create
- documentations fixes thanks to frioux
- fix documentation bug RT#96765, thanks to Salvatore Bonaccorso.
1.994 2014/06/22
- IO::Socket::SSL can now be used as dual-use socket, e.g. start plain, upgrade
  to SSL and downgrade again all with the same object. See documentation of
  SSL_startHandshake and chapter Advanced Usage.
- try to apply SSL_ca* even if verify_mode is 0, but don't complain if this
  fails. This is needed if one wants to explicitly verify OCSP lookups even if
  verification is otherwise off, because otherwise the signature check would
  fail. This is mostly useful for testing.
- reorder documentation of attributes for new, so that the more important ones
  are at the top.
1.993 2014/06/13
- major rewrite of documentation, now in separate file
- rework error handling to distinguish between SSL errors and internal errors
  (like missing capabilities).
- fix handling of default_ca if given during the run of the program (Debian#750646)
- util/analyze-ssl.pl - fix hostname check if SNI does not work
1.992 2014/06/01
- set $! to undef before doing IO (accept, read..). On Windows a connection
  reset could cause SSL read error without setting $!, so make sure we don't
  keep the old value and maybe thus run into endless loop.
1.991 2014/05/27
- new option SSL_OCSP_TRY_STAPLE to enforce staple request even if
  VERIFY_NONE
- work around for RT#96013 in peer_certificates
1.990 2014/05/27
- added option SSL_ocsp_staple_callback to get the stapled OCSP response
  and verify it somewhere else
- try to fix warnings on Windows again (#95967)
- work around temporary OCSP error in t/external/ocsp.t
1.989 2014/05/24
- fix #95881 (warnings on windows), thanks to TMHALL
1.988 2014/05/17
- add transparent support for DER and PKCS#12 files to specify cert and key,
  e.g. it will autodetect the format
- if SSL_cert_file is PEM and no SSL_key_file is given it will check if
  the key is in SSL_cert_file too
1.987 2014/05/17
- fix t/verify_hostname_standalone.t on systems without usable IDNA or IPv6
  #95719, thanks srchulo
- enable IPv6 support only if we have a usable inet_pton
- remove stale entries from MANIFEST (thanks seen[AT]myfairpoint[DOT]net)
1.986 2014/05/16
- allow IPv4 in common name, because browsers allow this too. But only for
  scheme www/http, not for rfc2818 (because RC2818 does not allow this).
  In default scheme IPv6 and IPv4 are allowed in CN.
  Thanks to heiko[DOT]hund[AT]sophos[DOT]com for reporting the problem.
- Fix handling of public suffix. Add exemption for *.googleapis.com
  wildcard, which should be better not allowed according to public suffix
  list but actually is used.
- Add hostname verification test based on older test of chromium. But change
  some of the test expectations because we don't want to support IP as SAN
  DNS and because we enforce a public suffix list (and thus *.co.uk should
  not be allowed)
1.985 2014/05/15
- make OCSP callback return 1 even if it was called on the server side
  because of bad setup of the socket. Otherwise we get an endless calling
  of the OCSP callback.
- consider an OCSP response which is not yet or no longer valid a soft error
  instead of a hard error
- fix skip in t/external/ocsp.t in case fingerprint does not match
- RT#95633 call EVP_PKEY_free not EVP_KEY_free in
  IO::Socket::SSL::Utils::KEY_free. Thanks to paul[AT]city-fan[DOT]org
- util/analyze.pl - with --show-chain check if chain with SNI is different
  from chain w/o SNI.
1.984 2014/05/10
- added OCSP support:
  - needs Net::SSLeay >=1.59
  - for usage see documentation of IO::Socket::SSL (examples and anything with
    OCSP in the name)
- new tool util/analyze-ssl.pl which is intended to help in debugging of SSL
  problems and to get information about capabilities of server. Works also
  as en example of how to use various features (like OCSP, SNI..)
- fix peer_certificates (returns leaf certificate only once on client side)
- added timeout for stop_SSL (either with Timeout or with the default
  timeout for IO::Socket)
- fix IO::Socket::SSL::Utils mapping between ASN1_TIME and time_t when local
  time is not GMT. Use Net::SSLeay::ASN1_TIME_timet if available.
- fix t/external/usable_ca.t for system with junk in CA files
1.983 2014/05/03
- fix public suffix handling: ajax.googleapis.com should be ok even if googleapis.com
  is in public suffix list (e.g. check one level less)
  #95317, thanks to purification[AT]ukr[DOT]net
- usable_ca.t - update fingerprints after heartbleed attack
- usable_ca.t - make sure we have usable CA for tested hosts in CA store
1.982 2014/04/24
- fix for using subroutine as argument to set_args_filter_hack
1.981 2014/04/08
- #95432 fix ecdhe Test for openssl1.0.1d, thanks to  paul[AT]city-fan[DOT]org
- fix detection of openssl1.0.1d (detected 1.0.1e instead)
- new function can_ecdh in IO::Socket::SSL
1.980 2014/04/08
- fixed incorrect calculation of certificate fingerprint in get_fingerprint*
  and comparison in SSL_fingerprint. Thanks to
  david[DT]palmer[AT]gradwell[DOT]com for reporting.
- disable elliptic curve support for openssl 1.0.1d on 64bit because of
  openssl rt#2975
1.979 2014/04/06
- hostname checking:
  - configuration of 'leftmost' is renamed to 'full_label', but the old
    version is kept for compatibility reasons.
  - documentation of predefined schemes fixed to match reality
1.978 2014/04/04
- RT#94424 again, fix test on older openssl version with no SNI support
1.977 2014/04/04
- fix publicsuffix for IDNA, more tests with various IDNA libs
  RT#94424. Thanks to paul[AT]city-fan[DOT]org
- reuse result of IDN lib detection from PublicSuffix.pm in SSL.pm
- add more checks to external/usable_ca.t. Now it is enough that at least
  one of the hosts verifies against the builtin CA store
- add openssl and Net::SSleay version to diagnostics in load test
1.976 2014/04/03
- added public prefix checking to verification of wildcard certificates,
  e.g. accept *.foo.com but not *.co.uk.
  See documentation of SSL_verifycn_publicsuffix and
  IO::Socket::SSL::PublicSuffix
  Thanks to noloader for pointing out the problem.
1.975 2014/04/02
- BEHAVIOR CHANGE: work around TEA misfeature on OS X builtin openssl, e.g.
  guarantee that only the explicitly given CA or the openssl default CA will
  be used. This means that certificates inside the OS X keyring will no
  longer be used, because there is no way to control the use by openssl
  (e.g. certificate pinning etc)
- make external tests run by default to make sure default CA works on all
  platforms, it skips automatically on network problems like timeouts or ssl
  interception, can also use http(s)_proxy environment variables
1.974 2014/04/02
- new function peer_certificates to get the whole certificate chain, needs
  Net::SSLeay>=1.58
- extended IO::Socket::Utils::CERT_asHash to provide way more information,
  like issuer information, cert and pubkey digests, all extensions, CRL
  distributions points and OCSP uri
1.973 2014/03/25
- with SSL_ca certificate handles can now be used additionally to
  SSL_ca_file and SSL_ca_path
- do not complain longer if SSL_ca_file and SSL_ca_path are both given,
  instead add both as options to the CA store
- Shortcut 'issuer' to give both issuer_cert and issuer_key in CERT_create.
1.972 2014/03/23
- make sure t/external/usable_ca.t works also with older openssl without
  support for SNI. RT#94117. Thanks to paul[AT]city-fan[DOT]org
1.971 2014/03/22
- try to use SSL_hostname for hostname verification if no SSL_verifycn_name
  is given. This way hostname for SNI and verification can be specified in
  one step.
- new test program example/simulate_proxy.pl
1.970 2014/03/19
- fix rt#93987 by making sure sub default_ca does use a local $_ and not a
  version of an outer scope which might be read-only.  Thanks to gshank
1.969 2014/03/13
- fix set_defaults to match documentation regarding short names
- new function set_args_filter_hack to make it possible to override bad SSL
  settings from other code at the last moment.
- determine default_ca on module load (and not on first use in each thread)
- don't try default hostname verification if verify_mode 0
- fix hostname verification when reusing context
1.968 2014/03/13
- BEHAVIOR CHANGE: removed implicit defaults of certs/server-{cert,key}.pem
  for SSL_{cert,key}_file and ca/,certs/my-ca.pem for SSL_ca_file.
  These defaults were depreceated since 1.951 (2013/7/3).
- Usable CA verification path on Windows etc:
  Do not use Net::SSLeay::CTX_set_default_verify_paths any longer to set
  system/build dependent default verification path, because there was no
  way to retrieve these default values and check if they contained usable
  CA. Instead re-implement the same algorithm and export the results with
  public function default_ca() and make it possible to overwrite it.
  Also check for usable verification path during build.
  If no usable path are detected require Mozilla::CA at build and try to
  use it at runtime.
1.967 2014/02/06
- verify the hostname inside a certificate by default with a superset of
  common verification schemes instead of not verifying identity at all.
  For now it will only complain if name verification failed, in the future
  it will fail certificate verification, forcing you to set the expected
  SSL_verifycn_name if you want to accept the certificate.
- new option SSL_fingerprint and new methods get_fingerprint and
  get_fingerprint_bin. Together they can be used to selectively accept
  specific certificates which would otherwise fail verification, like
  self-signed, outdated or from unknown CAs.
  This makes another reason to disable verification obsolete.
- Utils:
  - default RSA key length 2048
  - digest algorithm to sign certificate in CERT_create can be given,
    defaults to SHA-256
  - CERT_create can now issue non-CA selfsigned certificate
  - CERT_create add some more useful constraints to certificate
- spelling fixes, thanks to ville[dot]skytta[at]iki[dot]fi
1.966 2014/01/21
- fixed bug introduced in 1.964 - disabling TLSv1_2 worked no longer with
  specifying !TLSv12, only !TLSv1_2 worked
- fixed leak of session objects in SessionCache, if another session
  replaced an existing session (introduced in 1.965)
1.965 2014/01/16
- new key SSL_session_key to influence how sessions are inserted and looked
  up in the clients session cache. This makes it possible to share sessions
  over different ip:host (like required with some FTPS servers)
- t/core.t - handle case, were default loopback source is not 127.0.0.1, like
  in FreeBSD jails
1.964 2014/01/15
- Disabling TLSv1_1 did not work, because the constant was wrong. Now it gets
  the constants from calling Net::SSLeay::SSL_OP_NO_TLSv1_1 etc
- The new syntax for the protocols is TLSv1_1 instead of TLSv11. This matches
  the syntax from OpenSSL. The old syntax continues to work in SSL_version.
- New functions get_sslversion and get_sslversion_int which get the SSL version
  of the establish session as string or int.
- disable t/io-socket-inet6.t if Acme::Override::INET is installed
1.963 2014/01/13
- fix behavior of stop_SSL: for blocking sockets it now enough to call it
  once, for non-blocking it should be called again as long as EAGAIN and
  SSL_ERROR is set to SSL_WANT_(READ|WRITE).
- don't call blocking if start_SSL failed and downgraded socket has no
  blocking method, thanks to tokuhirom
- documentation enhancements:
  - special section for differences to IO::Socket
  - describe problem with blocking accept on non-blocking socket
  - describe arguments to new_from_fd and make clear, that for upgrading an
    existing IO::Socket start_SSL should be used directly
1.962 2013/11/27
- work around problems with older F5 BIG-IP by offering fewer ciphers on the
  client side by default, so that the client hello stays below 255 byte
1.961 2013/11/26
- IO::Socket::SSL::Utils::CERT_create can now create CA-certificates which
  are not self-signed (by giving issuer_*)
1.960 2013/11/12
only documentation enhancements:
- clarify with text and example code, that within event loops not only
  select/poll should be used, but also pending has to be called.
- better introduction into SSL, at least mention anonymous authentication as
  something you don't want and should take care with the right cipher
- make it more clear, that user better does not change the cipher list, unless
  he really know what he is doing
1.959 2013/11/12
- bugfix test core.t windows only
1.958 2013/11/11
- cleanup: remove workaround for old IO::Socket::INET6 but instead require at
  least version 2.55 which is now 5 years old
- fix t/session.t #RT90240, thanks to  paul[AT]city-fan[DOT]org
1.957 2013/11/11
- fixed t/core.t: test uses cipher_list of HIGH, which includes anonymous
  authorization. With the DH param given by default since 1.956 old versions of
  openssl (like 0.9.8k) used cipher ADH-AES256-SHA (e.g. anonymous
  authorization) instead of AES256-SHA and thus the check for the peer
  certificate failed (because ADH does not exchanges certificates).
  Fixed by explicitly specifying HIGH:!aNULL as cipher
  RT#90221, thanks to  paul[AT]city-fan[DOT]org
- cleaned up tests:
  - remove ssl_settings.req and 02settings.t, because all tests now create a
    simple socket at 127.0.0.1 and thus global settings are no longer needed.
  - some tests did not have use strict(!), fixed it.
  - removed special handling for older Net::SSLeay versions, which are less than
    our minimum requirement
  - some syntax enhancements, removed some SSL_version and SSL_cipher_list
    options where they were not really needed
1.956 2013/11/10
lots of behavior changes for more secure defaults:
- BEHAVIOR CHANGE: make default cipher list more secure, especially
  - no longer support MD5 by default (broken)
  - no longer support anonymous authentication by default (vulnerable to man in
    the middle attacks)
  - prefer ECDHE/DHE ciphers and add necessary ECDH curve and DH keys, so that
    it uses by default forward secrecy, if underlying Net::SSLeay/openssl
    supports it
  - move RC4 at the end, e.g. 3DES is preferred (BEAST attack should hopefully
    been fixed and now RC4 is considered less safe than 3DES)
  - default SSL_honor_cipher_order to 1, e.g. when used as server it tries to
    get the best cipher even if client prefers other ciphers
  PLEASE NOTE that this might break connections with older, less secure
  implementations. In this case revert to 'ALL:!LOW:!EXP:!aNULL' or so.
- BEHAVIOR CHANGE: SSL_cipher_list now gets set on context not SSL object and
  thus gets reused if context gets reused. PLEASE NOTE that using
  SSL_cipher_list together with SSL_reuse_ctx has no longer effect on the
  ciphers of the context.
- rework hostname verification schemes
  - add rfc names as scheme (e.g. 'rfc2818',...)
  - add SIP, SNMP, syslog, netconf, GIST
  - BEHAVIOR CHANGE: fix SMTP - now accept wildcards in CN and subjectAltName
  - BEHAVIOR CHANGE: fix IMAP, POP3, ACAP, NNTP - now accept wildcards in CN
- BEHAVIOR CHANGE: anywhere wildcards like www* now match only 'www1', 'www2'..
  but not 'www'
- anywhere wildcards like x* are no longer applied to IDNA names (which start
  with 'xn--')
- fix crash of Utils::CERT_free
- support TLSv11, TLSv12 as handshake protocols
1.955 2013/10/11
- support for forward secrecy using ECDH, if the Net::SSLeay/openssl version
  supports it.
1.954 2013/9/15
- accept older versions of ExtUtils::MakeMaker and add meta information
  like link to repository only for newer versions.
1.953 2013/7/22
- fixes to IO::Socket::SSL::Utils, thanks to rurban[AT]x-ray[DOT]at,
  RT#87052
1.952 2013/7/11
- fix t/acceptSSL-timeout.t on Win32, RT#86862
1.951 2013/7/3
- better document builtin defaults for key,cert,CA and how they are depreceated
- use Net::SSLeay::CTX_set_default_verify_paths to use openssl's builtin
  defaults for CA unless CA path/file was given (or IO::Socket::SSL builtins
  used)
1.950 2013/7/3
- MAJOR BEHAVIOR CHANGE:
  ssl_verify_mode now defaults to verify_peer for client.
  Until now it used verify_none, but loudly complained since 1.79 about it.
  It will not complain any longer, but the connection might probably fail.
  Please don't simply disable ssl verification, but instead set SSL_ca_file
  etc so that verification succeeds!
- MAJOR BEHAVIOR CHANGE:
  it will now complain if the builtin defaults of certs/my-ca.pem or ca/
  for CA and certs/{server,client}-{key,cert}.pem for cert and key are used,
  e.g. no certificates are specified explicitly.
  In the future these insecure (relative path!) defaults will be removed
  and the CA replaced with the system defaults.
v1.94 2013.06.01
- Makefile.PL reported wrong version of openssl, if Net::SSLeay was not
  installed instead of reporting missing dependency to Net::SSLeay.
v1.93 2013.05.31
- need at least OpenSSL version 0.9.8 now, since last 0.9.7 was released 6
  years ago. Remove code to work around older releases.
- changed AUTHOR in Makefile.PL from array back to string, because the
  array feature is not available in MakeMaker shipped with 5.8.9 (RT#85739)
v1.92 2013.05.30
- Intercept: use sha1-fingerprint of original cert for id into cache unless
  otherwise given
- Fix pod error in IO::Socket::SSL::Utils RT#85733
v1.91 2013.05.30
- added IO::Socket::SSL::Utils for easier manipulation of certificates and keys
- moved SSL interception into IO::Socket::SSL::Intercept and simplified it
  using IO::Socket::SSL::Utils
- enhance meta information in Makefile.PL
v1.90 2013.05.27
- RT#85290, support more digest, especially SHA-2.
  Thanks to ujvari[AT]microsec[DOT]hu
- added support for easy SSL interception (man in the middle) based
  on ideas found in mojo-mitm proxy (which was written by Karel Miko)
- make 1.46 the minimal required version for Net::SSLeay, because it
  introduced lots of useful functions.
v1.89 2013.05.14
- if IO::Socket::IP is used it should be at least version 0.20, otherwise
  we get problems with HTTP::Daemon::SSL and maybe others (RT#81932)
- Spelling corrections, thanks to dsteinbrunner
v1.88 2013.05.02
- consider a value of '' the same as undef for SSL_ca_(path|file), SSL_key*
  and SSL_cert* - some apps like Net::LDAP use it that way.
  Thanks to alexander[AT]kuehn[AT]nagilum[DOT]de for reporting the problem.
v1.87 2013.04.24
- RT#84829 - complain if given SSL_(key|cert|ca)_(file|path) do not exist or
  if they are not readable. Thanks to perl[AT]minty[DOT]org
- fix use of SSL_key|SSL_file objects instead of files, broken with 1.83
v1.86 2013.04.17
- RT#84686 - don't complain about SSL_verify_mode is SSL_reuse_ctx,
  thanks to CLEACH
v1.85 2013.04.14
- probe for available modules with local __DIE__ and __WARN__handlers.
  fixes RT#84574, thanks to FRAZER
- fix warning, when IO::Socket::IP is installed and inet6 support gets explicitly
  requested. RT#84619, thanks to Prashant[DOT]Tekriwal[AT]netapp[DOT]com
v1.84 2013.02.15
- disabled client side SNI for openssl version < 1.0.0 because of RT#83289
- added functions can_client_sni, can_server_sni, can_npn to check availability
  of SNI and NPN features. Added more documentation for SNI and NPN.
v1.83_1 2013.02.14
- separated documentation of non-blocking I/O from error handling
- changed and documented behavior of readline to return the read
  data on EAGAIN/EWOULDBLOCK in case of non-blocking socket.
  See https://github.com/noxxi/p5-io-socket-ssl/issues/1, thanks to
  mytram
v1.83 2013.02.03
- Server Name Indication (SNI) support on the server side, inspired by
  patch provided by karel[DOT]miko[AT]gmail[DOT]com.
  https://rt.cpan.org/Ticket/Display.html?id=82761
- reworked part of the documentation, like providing better examples.
v1.82 2013.01.28
- sub error sets $SSL_ERROR etc only if there really is an error,
  otherwise it will keep the latest error. This causes
  IO::Socket::SSL->new.. to report the correct problem, even if
  the problem is deeper in the code (like in connect)
- correct spelling, rt#8270. Thanks to ETHER
v1.81 2012.12.06
- deprecated set_ctx_defaults, new name ist set_defaults (but old name
  still available)
- changed handling of default path for SSL_(ca|cert|key)* keys: either
  if one of these keys is user defined don't add defaults for the
  others, e.g.  don't mix user settings and defaults
- cleaner handling of module defaults vs. global settings vs. socket
  specific settings. Global and socket specific settings are both
  provided by the user, while module defaults not.
- make IO::Socket::INET6 and IO::Socket::IP specific tests run both,
  even if both modules are installed by faking a failed load of the
  other module.
v1.80 2012.11.30
- removed some warnings in test (missing SSL_verify_mode => 0) which
  caused tests to hang on Windows.
  https://rt.cpan.org/Ticket/Display.html?id=81493
v1.79 2012.11.25
- prepare transition to a more secure default for SSL_verify_mode.
  The use of the current default SSL_VERIFY_NONE will cause a big warning
  for clients, unless SSL_verify_mode was explicitly set inside the
  application to this insecure value.
  In the near future the default will be SSL_VERIFY_PEER, and thus
  causing verification failures in unchanged applications.
v1.78 2012.11.25
- use getnameinfo instead of unpack_sockaddr_in6 to get PeerAddr and
  PeerPort from sockaddr in _update_peer, because this provides scope
  too. Thanks to bluhm[AT]genua[DOT]de.
- work around systems which don't defined AF_INET6
  https://rt.cpan.org/Ticket/Display.html?id=81216
  Thanks to GAAS for reporting
v1.77 2012.10.05
- update_peer for IPv6 also, applied fix to
  https://rt.cpan.org/Ticket/Display.html?id=79916 by
  tlhackque[AT]yahoo[DOT]com
v1.76 2012.06.18
- no longer depend on Socket.pm 1.95 for inet_pton, but use Socket6.pm if
  no current Socket.pm is available. Thanks to paul[AT]city-fan[DOT]org
  for pointing out the problem and providing first patch
v1.75 2012.06.15
- made it possible to explicitly disable TLSv11 and TLSv12 in SSL_version
v1.74_2 2012.06.07
- fixed documentation errors, reported by MARSCHAP
  https://rt.cpan.org/Ticket/Display.html?id=77690
v1.74_1 2012.06.07
- add support to IO::Socket::IP which support inet6 and inet4 by
  integrating patch from PEVANS
  for https://rt.cpan.org/Ticket/Display.html?id=75218
v1.74 2012.05.13
- accept a version of SSLv2/3 as SSLv23, because older documentation
  could be interpreted like this
v1.73 2012.05.11
- make test t/dhe.t hopefully work for more version of openssl
  Thanks to paul[AT]city-fan[DOT]org for providing bug reports and
  testing environment
v1.72 2012.05.10
- set DEFAULT_CIPHER_LIST to ALL:!LOW instead of HIGH:!LOW
  Thanks to dcostas[AT]gmail[DOT]com for problem report
v1.71 2012.05.09
- 1.70 done right. Also don't disable SSLv2 ciphers, SSLv2 support is better
  disabled by the default SSL_version of 'SSLv23:!SSLv2'
v1.70 2012.05.08
- make it possible to disable protocols using SSL_version, make SSL_version
  default to 'SSLv23:!SSLv2'
v1.69 2012.05.08
- re-added workaround in t/dhe.t
v1.68 2012.05.07
- remove SSLv2 from default cipher list, which makes failed tests after last
  change work again, fix behavior for empty cipher list (use default)
v1.67 2012.05.07
- https://rt.cpan.org/Ticket/Display.html?id=76929
  thanks to d[DOT]thomas[AT]its[DOT]uq[DOT]edu[DOT]au for reporting
  - if no explicit cipher list is given it will now default to ALL:!LOW instead
    of the openssl default, which usually includes weak ciphers like DES.
  - new config key SSL_honor_cipher_order and documented how to use it to fight
    BEAST attack.
v1.66 2012.04.16
- make it thread safer, thanks to bug report from vega[DOT]james[AT]gmail
  [DOT]com, https://rt.cpan.org/Ticket/Display.html?id=76538
v1.65 2012.04.16
- added NPN (Next Protocol Negotiation) support based on patch from kmx
  https://rt.cpan.org/Ticket/Display.html?id=76223
v1.64 2012.04.06
- clarify some behavior regarding hostname verification.
  Thanks to DOHERTY for reporting.
v1.63 2012.04.06
- applied patch of DOUGDUDE to ignore die from within eval to make tests
  more stable on Win32, https://rt.cpan.org/Ticket/Display.html?id=76147
v1.62 2012.03.28
- small fix to last version
v1.61 2012.03.27
