    Hi James.
    A little bit work for you.
    Somebody on mailing list commented that you should *really* go for better
    algorithm like CAST6 (rfc2612) to be included in kernel.
    This time I'm sending you cast6.c (cast6 cipher algorithm) implementation.
    But this time it's a patch.
    I just want it get tested.
    I've tested it on i386 against kernel version 2.6.0-test3.
    Patch includes.
    1. cast6.c (new).
    2. tcrypt.c and tcrypt.h (modified).
