ID: 60221 Updated by: frozenf...@php.net Reported by: chadd at fidelissys dot com Summary: Tiger hash output byte order -Status: Open +Status: Closed Type: Bug Package: hash related Operating System: Linux PHP Version: 5.3.8 Assigned To: mike Block user comment: N Private report: N Previous Comments: ------------------------------------------------------------------------ [2012-01-27 23:12:23] frozenf...@php.net Automatic comment from SVN on behalf of frozenfire Revision: http://svn.php.net/viewvc/?view=revision&revision=322885 Log: Added changelog, indicating that the Tiger hash algorithm now uses big-endian byte ordering. Closes bug #60221. ------------------------------------------------------------------------ [2012-01-17 15:26:24] m...@php.net This bug has been fixed in SVN.

Thank you for the report, and for helping us make PHP better. ------------------------------------------------------------------------ [2011-11-04 18:27:50] chadd at fidelissys dot com Description: ------------ The testtiger program prints its hashes with each 8-byte chunk byte-swapped (perhaps arch-dependent?). The "24f0130c63ac9332..." hash of the tiger*,3 family would be printed "3293ac630c13f024..." in MSB-first representation, e.g. as given on Wikipedia's example output. Perl's Digest::Tiger also uses the MSB-first format: http://search.cpan.org/~clintdw/Digest-Tiger-0.03/Tiger.pm#NOTE The lack of MSB-first order potentially impacts interoperability, but changing the output of "tiger192,3" would break BC with anyone who doesn't have interop problems. This bug has been observed in php 5.2.6 as well. Test script: --------------- <?php echo hash('tiger192,3', ''), "\n"; ?> Expected result: ---------------- 3293ac630c13f0245f92bbb1766e16167a4e58492dde73f3 Actual result: -------------- 24f0130c63ac933216166e76b1bb925ff373de2d49584e7a ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60221&edit=1
