Turn off with -nodeprecate=>1 or by choosing a different PBKDF, such as -pbkdf=>'pbkdf2'. - Fix a regression when passing the legacy -salt=>1 argument. 3.00 Sun Feb 7 10:28:08 EST 2021 - Released version 3.00 in recognition of multiple new features and cleanups. 2.37 Sun Feb 7 10:20:17 EST 2021 - Added better argument checking. - Fixed long-standing standard padding bug: plaintext ending with bytes between 0x00 and 0x0A would be truncated in some conditions. - Fixed Rijndael_compat padding. 2.36 Wed 03 Feb 2021 09:19:06 AM EST - Add support for OFB, CFB and CTR chain modes. - New dependency: Math::BigInt 2.35 Sun Jan 31 22:02:42 EST 2021 - Add support for PBKDF2 key derivation algorithm - New dependencies: Digest::SHA, Crypt::PBKDF2, Crypt::Cipher::AES 2.34 Fri Jan 29 18:08:12 EST 2021 - Support for openssl SHA-256 key derivation algorithm 2.33 Tue Jul 30 16:02:04 EDT 2013 - Fix minor RT bugs 83175 and 86455. 2.32 Fri Dec 14 14:20:17 EST 2012 - Fix "Taint checks are turned on and your key is tainted" error when autogenerating salt and IV. 2.31 Tue Oct 30 07:03:40 EDT 2012 - Fixes to regular expressions to avoid rare failures to correctly strip padding in decoded messages. - Add padding type = "none". - Both fixes contributed by Bas van Sisseren. 2.29 Tue Apr 22 10:22:37 EDT 2008 - Fixed errors that occurred when encrypting/decrypting utf8 strings in Perl's more recent than 5.8.8. 2.28 Mon Mar 31 10:46:25 EDT 2008 - Fixed bug in onesandzeroes test that causes it to fail with Rijndael module is not installed. 2.27 Fri Mar 28 10:13:32 EDT 2008 - When taint mode is turned on and user is using a tainted key, explicitly check tainting of key in order to avoid "cryptic" failure messages from some crypt modules. 2.26 Thu Mar 20 16:41:23 EDT 2008 - Fixed onezeropadding test, which was not reporting its test count properly. 2.25 Fri Jan 11 15:26:27 EST 2008 - Fixed failure of oneandzeroes padding when plaintext size is an even multiple of blocksize. - Added new "rijndael_compat" padding method, which is compatible with the oneandzeroes padding method used by Crypt::Rijndael in CBC mode. 2.24 Fri Sep 28 11:21:07 EDT 2007 - Fixed failure to run under taint checks with Crypt::Rijndael or Crypt::OpenSSL::AES (and maybe other Crypt modules). See http://rt.cpan.org/Public/Bug/Display.html?id=29646. 2.23 Fri Apr 13 14:50:21 EDT 2007 - Added checks for other implementations of CBC which add no standard padding at all when cipher text is an even multiple of the block size. 2.22 Sun Oct 29 16:50:32 EST 2006 - Fixed bug in which plaintext encrypted with the -literal_key option could not be decrypted using a new object created with the same -literal_key. - Added documentation confirming that -literal_key must be accompanied by a -header of 'none' and a manually specificied IV. 2.21 Mon Oct 16 19:26:26 EDT 2006 - Fixed bug in which new() failed to work when first option is -literal_key. 2.20 Sat Aug 12 22:30:53 EDT 2006 - Added ability to pass a preinitialized Crypt::* block cipher object instead of the class name. - Fixed a bug when processing -literal_key. 2.19 Tue Jul 18 18:39:57 EDT 2006 - Renamed Crypt::CBC-2.16-vulnerability.txt so that package installs correctly under Cygwin 2.18 2006/06/06 23:17:04 - added more documentation describing how to achieve compatibility with old encrypted messages 2.17 Mon Jan 9 18:22:51 EST 2006 -IMPORTANT NOTE: Versions of this module prior to 2.17 were incorrectly using 8 byte IVs when generating the old-style RandomIV style header (as opposed to the new-style random salt header). This affects data encrypted using the Rijndael algorithm, which has a 16 byte blocksize, and is a significant security issue. The bug has been corrected in versions 2.17 and higher by making it impossible to use 16-byte block ciphers with RandomIV headers. You may still read legacy encrypted data by explicitly passing the -insecure_legacy_decrypt option to Crypt::CBC->new(). -The salt, iv and key are now reset before each complete encryption cycle. This avoids inadvertent reuse of the same salt. -A new -header option has been added that allows you to select among the various types of headers, and avoids the ambiguity of having multiple interacting options. -A new random_bytes() method provides access to /dev/urandom on suitably-equipped hardware. 2.16 Tue Dec 6 14:17:45 EST 2005 - Added two new options to new(): -keysize => <bytes> Force the keysize -- useful for Blowfish -blocksize => <bytes> Force the blocksize -- not known to be useful ("-keysize=>16" is necessary to decrypt OpenSSL messages encrypted with Blowfish) 2.15 Thu Nov 17 17:34:28 EST 2005 - -add_header=>0 now explicitly turns off any attempt of parsing the header in decrypt routines. 2.14 Thu May 5 16:08:15 EDT 2005 - RandomIV in message header overrides manually-supplied -salt, as one would expect it should. 2.13 Fri Apr 22 13:01:32 EDT 200 - Added OpenSSL compatibility - Salt and IV generators take advantage of /dev/urandom device, if available - Reorganized internal structure for coding clarity - Added regression test for PCBC mode 2.12 Thu Jun 17 11:52:04 EDT 2004 - quenched (again) uninitialized variable warnings 2.11 Thu Jun 3 12:07:33 EDT 2004 -Fixed bug reported by Joshua Brown that caused certain length strings to not encrypt properly if ending in a "0" character. 2.10 Sat May 29 13:10:05 EDT 2004 -Fixed Rijndael compat problems 2.09 Thu May 27 11:18:06 EDT 2004 -Quenched uninitialized variable warnings 2.08 Wed Sep 11 08:12:49 EDT 2002 -Bug fix from Chris Laas to fix custom padding 2.07 Thu Aug 8 14:44:52 EDT 2002 -Bug fixes from Stephen Waters to fix space padding -Lots of regression tests from Stephen Waters 2.05 Tue Jun 11 22:18:04 EDT 2002 -Makes zero-and-one padding compatible with Crypt::Rijndael::MODE_CBC. -Lots of improvements to padding mechanisms from Stephen Waters 2.04 Tue Jun 11 22:18:04 EDT 2002 WITHDRAWN VERSION DO NOT USE 2.03 Mon Feb 4 15:41:51 EST 2002 -Patch from Andy Turner <turner@mikomi.org> to allow backward compatibility with old versions when key length exceeded max. 2.02 Thu Jan 24 00:15:52 EST 2002 - Default to pre-2.00 style padding, because Jody's default padding method was not binary safe. 2.01 Mon Dec 10 12:11:35 EST 2001 - Removed debugging code. 2.00 Tue Oct 31, 2000 - Patches for foreign program compatibility, initialization vectors and padding methods from Jody Biggs <jody.biggs@paymybills.com> 1.25 Thu Jun 8 11:56:28 EDT 2000 - Bug fix didn't get into version 1.24. Is in version 1.25 1.24 Tue Jun 6 17:35:18 EDT 2000 - Fixed a bug that prevented a DES and an IDEA object from being used simultaneously. 1.22 Wed Jan 26 19:07:30 EST 2000 - Added support for Crypt::Blowfish (available from www.cryptix.org) - Fixed failure to encrypt data files < 8 bytes - Fixed -w warning when decrypting data files < 8 bytes 1.21 Mon Nov 29 17:11:17 EST 1999 - Generate random initialization vector. - Use same encryption format as Ben Laurie's patches to OpenSSL (versions >= 0.9.5) 1.20 Sun Dec 20 3:58:01 1998 MET - Folded in bug fixes from Devin Carraway <aqua@sonic.net> (chiefly having to do with finish() being called with a zero-length buffer). 1.10 Thu Sep 11 09:15:01 1998 - Changed package name to Crypt::CBC 1.00 Tue Jun 16 07:37:35 1998 - original version; created by h2xs 1.18
