Bug#575038: libgcrypt11: tiger192 message digest does not agree with other implementations

[Werner Koch]

Hi!

Okay, I implemented the the two variants and moved the assigned OID to
the TIGER vesion which matches the NESSIE results.  It is in the SVN
trunk, r1425.  Tested on ia32 and ppc64, thus there should be no endian
issues.

`GCRY_MD_TIGER'
     This is the TIGER/192 algorithm which yields a message digest of 24
     bytes.  Actually this is a variant of TIGER with a different output
     print order as used by GnuPG up to version 1.3.2.

`GCRY_MD_TIGER1'
     This is the TIGER variant as used by the NESSIE project.  It uses
     the most commonly used output print order.

`GCRY_MD_TIGER2'
     This is another variant of TIGER with a different padding scheme.

I don't think it makes much sense to port it back to the stable branch.


Salam-Shalom,

   Werner
