[ SEA-GHOST MINI SHELL]

Revision history for Perl extension Net::SSLeay.

1.55 2013-06-08
     Added support for TLSV1_1 and TLSV1_2 methods with SSL_CTX_tlsv1_1_new(),
     SSL_CTX_tlsv1_2_new(), TLSv1_1_method() and TLSv1_2_method(), where
     available in the underlying openssl.
     Added CRL support functions X509_CRL_get_ext(), X509_CRL_get_ext_by_NID(),
     X509_CRL_get_ext_count(). Patch from Franck Youssef.
     Fixed a problem which could cause content with a value of '0' to not be
     correctly encoded by do_httpx3 and friends. Reported by Victor Efimov via
     RT.
     Added support for SSL_get_tlsa_record_byname() required for DANE support in
     openssl-1.0.2 and later. SSL_get_tlsa_record_byname() was added to
     OpenSSL with the financial assistance of .SE.
     Testing with openssl-1.0.2-stable-SNAP-20130521.
     Added X509_NAME_new and X509_NAME_hash, patched by Franck Youssef.

1.54 2013-03-23
     t/data/testcert_cdp.crt.pem_dump and t/data/testcert_cdp.crt.pem were
     missing from MANIFEST.
     Added MANIFEST to svn
     Improvement to test 07_sslecho.t so that if set_cert_and_key fails we
     can tell why.

1.53 2013-03-22
     Added support for SSL_export_keying_material where present (ie in OpenSSL
     1.0.1 and later).
     Changed t/handle/external/50_external.t to use www.airspayce.com instead of
     perldition.org, who no longer have an https server.
     Patch to fix a crash: P_X509_get_crl_distribution_points on an
     X509 certificate with values in the CDP extension which do not have an
     ia5 string will cause a segmentation fault when accessed. Patch from
     Robert Duncan.
     Change in t/local/32_x509_get_cert_info.t to not use
     Net::SSLeay::ASN1_INTEGER_get, since it works differntly on 32 and 64 bit platforms.
     Updated author and distribution location details to airspayce.com


1.52 2013-01-09
     Rebuild package with gnu format tar, to prevent problems with unpacking
     on other systems such as old Solaris,

1.51 2012-12-14
     Fixed a problem where SSL_set_SSL_CTX is not available with
     OpenSSL < 0.9.8f. Reported by Paul.

1.50 2012-12-13 
     Fixed a problem where t/handle/external/50_external.t would crash if any
     of the test sites were not contactable.
     Now builds on VMS. Patch kindly supplied by Craig A. Berry.
     Fixed a few compiler warnings in SSLeay.xs.  Most of them
     are just signed/unsigned pointer mismatches but there is one that actually
     fixes returning what would be an arbitrary value off the stack from
     get_my_thread_id if it happened to be called in a non-threaded build.
     Patch kindly supplied by Craig A. Berry.
     Added README.VMS, contributed by Craig A. Berry.
     Added SSL_set_tlsext_host_name, SSL_get_servername,
     SSL_get_servername_type, SSL_CTX_set_tlsext_servername_callback for
     server side Server Name Indication (SNI) support. Patched by kmx.
     Further mods for VMS building supplied by Craig A. Berry.
     Fixed a problem with C++ comments preventing builds on AIX and
     HPUX. Patched by Gisle Aas.
     perdition.org not available for tests, changed to www.airspayce.com
     Added SSL_FIPS_mode_set
     Improvements to test suite so it succeeds with and without FIPS mode
     enabled. Patch supplied by Petr Pisar.
     Added documentation, warning not to pass UTF-8 data in the content
     argument to post_https. Reported by Jason Terry.

1.49 2012-09-25
     Fixed problem where on some platforms test t/local/07_tcpecho.t would
     bail out if it could not bind port 1212. Now now tries a number of ports to bind to until
     successful.
     Improvements to  unsigned casting contributed by Reini Urban.
     Improvements to Net::SSLeay::read to make it easier to use with non-blocking IO:
      contributed by James Marshall:  It modifies
      Net::SSLeay::read() to return the result from SSL_read() as the second
      return value, if Net::SSLeay::read() is called in list context.  Its
      behavior should be unchanged if called in scalar or void context.  This
      result code seems to be required for full support of non-blocking I/O,
      since users need to handle SSL_ERR_WANT_READ, SSL_ERROR_WANT_WRITE, etc.
      Fixed a problem where t/local/kwalitee.t fails with
       Module::CPANTS::Analyse 0.86. Patch from Paul.
      Fixed a number of typos patched by Giles.
      Fixed a compiler warning from Compiling with gcc-4.4 and -Wall, patched by Giles.	
      Fixed problems with get_https4: documentation was wrong, $header_ref was
       not correctly set and $server_cert was not returned.
      Fixed a problem that could cause a Perl exception about no blength
      method on undef. Reported by "Stephen J. Smith via RT". https://rt.cpan.org/Ticket/Display.html?id=79309 
      Added documentation about how to mitigatxe various SSL/TLS
     vulnerabilities.
     Fixed problem reported by Mike Doherty: SSL_MODE_* are defined in ssl.h, 
     and should be available as constants, but I do not see them listed in constants.h

1.48 2012-04-25
     Removed unneeded Debian_CPANTS.txt from MANIFEST.
     Fixed incorrect documentation about the best way to call CTX_set_options.
     Fixed problem that caused Undefined subroutine utf8::encode @
     t/local/33_x509_create_cert.t (on perl 5.6.2). Thanks to kmx.
     In examples and pod documentations, changed #!/usr/local/bin/perl to #!/usr/bin/perl.
     t/local/06_tcpecho.t now tries a number of ports to bind to until
     successful.

1.47 2012-04-04
     Fixed overlong lines in pod, patch from Salvatore Bonaccorso, Debian Perl
     Group
     Fixed spelling errors in pod, patch from Salvatore Bonaccorso, Debian Perl
     Group
     Fixed extra "garbage" files in 1.46 tarball. Patch from kmx.
     Fixed incorrect fail reports on some 64 bit platforms. Patch from paul.
     Fix to avoid FAIL reports from cpantesters with missing openssl
     Use my_snprintf from ppport.h to prevent link failures with perl 5.8 and
     earlier when compiled with MSVC.

1.46 2012-04-03
     Fixed a problem reported by Atoomic: 
      When bootstrapping Net::SSleay ( with DynaLoader ) if you override the SIG{DIE} signal, using 
      Net::SSLeay will result in an error.
      Recreated META.yml, added META.yml to dist
      Fixed typo: the word "corresponding" was mis-spelled as "coresponding"
       throughout the POD. Patched by kmx.
      Updated META.yml to include repository and bugtracker
     Constants cleanup - removing non existing constants (perhaps from pre-0.9.6 era) - kmx
     Automatic constants.c generation via helper_script/regen_openssl_constants.pl - kmx
     Future changes in constants now under better control via
     t/local/21_constants.t - kmx
     Added missing new files
     Reordering @EXPORT_OK (constants first, functions next) - kmx
     Adding missing 51 constants to @EXPORT_OK + test to keep it in sync - kmx

     Fixing X509_NAME_oneline (calling OPENSSL_free at the right place)
     Fixed a problem with crashing when run under apache2+modssl+modperl on
     Debian Wheezy. Now detects if it is running under ModPerl and uses ModSSLs
     thread locking instead.
     Added more debg printing. Enable with
     	   perl Makefile.PL DEFINE=-DSHOW_XS_DEBUG
     Added NPN support, thanks to kmx

1.43 2012-02-24
    Fixed some typos. Patched by Neil Bowers.
    SSLeay.pm convenience functions now call Net::SSLeay::initialize that
    initializes the SSL library at most once. 
    Patch from kmx to protect SSLeay_add_ssl_algorithms from multiple loads
    and reentrancy in multi-threaded perls.

    not opened in binary mode. Reported by kmx.
    Added resources line for SVN repository to Makefile. Suggested by kmx.
    Fixed complaints unders some windows compilers about cast from pointer to integer of
    different size. Suggested by kmx.
    Added thread safety and dynamic locking. This should complete thread
    safety work, making Net::SSLeay completely thread-safe. Patches by kind
    assistance of kmx.
    Improvements to openssl backwards compatibility. Now build with versions
    back to 0.9.6. With extreme thanks to kmx.
    Improvements to documentation, thanks to kmx.

      to 0.9.2b release. Thanks guys!
    - Detected errors in OpenSSL-0.9.2b/ssl/ssl.h - see patch in README
    - Reordered arguments of several functions to track OpenSSL-0.9.2b
      changes. This also changes the order of args in corresponding
      perl functions. You have been warned!
        - SSL_use_certificate_ASN1(s,d,len)  // swapped d and len
    - WARNING: Possibly fatal verify_callback parameter list issue
      is still standing
    - cleaned up many macros that used to access ctx->session directly,
      OpenSSL-0.9.2b defines thes macros properly so I use them now.
    - Added SSL_ctrl() and SSL_CTX_ctrl()
    - Added SSL_get_options(), SSL_CTX_get_options(),
      SSL_CTX_set_cipher_list()

      anymore. This used to cause headaches when connection
      renegotiation happened.
    - applied ssl_read_CRLF patch by Clinton Wong <clintdw@@netcom._com>
    - ActivePerl diffs from anton@@_genua.de applied,

    - changed $trace levels so that 0 does not produce any output
    - changed get_https and put_https to fake error 900 in $response
      return field
    - changed print_errs and some other internals to return textual
      errors instead of error count

    - added random number initialization using /dev/urandom (if available)
    - made ssl_write_all accept references, this is more memory efficient
1.00  19.6.1998, Sampo Kellomaki <sampo@@_iki.fi>
    - overhauled to SSLeay-0.9.0
    - renamed cat to sslcat
