NAME

Crypt::AppleTwoFish -- an Apple iTMS internal key descrambling algorithm

LANGUAGE

Pure Perl.

DESCRIPTION

This code appears to have only cursory resemblance to Bruce Schneier's 
blowfish and twofish algorithms in that it too has a table-based decoder.

Derivation from FairKeys code by Jon Lech Johanson at nanocrew.net. 
If you don't know what that is, don't bother looking here further. This is
a Pure Perl implementation. I doubt there is any need for xs coding for 
what would mainly be processing 16 bytes at a time. This code is part of an 
ongoing effort to clone portions of the Apple iTMS in Perl for portability. 
See www.hymn-project.org for prior efforts by others.

To install the module...

perl Makefile.PL
make
make test
make install

If you are on a windows box you should use 'nmake' rather than 'make'.
