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
