Bug #61307 [Nab]: hash-tiger generates a different value between 5.3/5.4

Edit report at https://bugs.php.net/bug.php?id=61307&edit=1 ID: 61307 Updated by: rasmus@php.net Reported by: andres at phalconphp dot com Summary: hash-tiger generates a different value between 5.3/5.4 Status: Not a bug Type: Bug Package: hash related Operating System: Irrelevant PHP Version: 5.4.0 Block user comment: N Private report: N New Comment: Yeah, I think we need to come up with a way to support both or else it leaves people without an easy way to fix those hashes. Technically I guess you can reconstruct it from the raw by flipping the bytes, but that is rather error- prone.

It looks like we have to keep PHP 5.3 for a long time. ------------------------------------------------------------------------ [2012-03-07 10:55:03] mike@php.net Thank you for taking the time to write to us, but this is not a bug.
