DFC definitly works. I tested it against the test vectors submited to
NIST during the AES competition. RC5 and IDEA however, seems not to work.
I did not have the same kind of official test vectors that I had for
DFC, but failing on one test vector is almost certainly the same as
a wringly implemened algorithm. I got the test vectors for idea and rc5 in
'Handbook of applied cryptography' (Menezes et al), but I'm not
absolutly certain that the test vectors had the right parameterization for
rc5 (but at least almost certain). This means that IDEA and RC5 probably
don't work. I will bring out the latest version of the cryptoapi from
CVS and test once more, since the one I used not was updated for a
while. I should also mention that I tested the ciphers, not that they
worked in a loopback context.

With sufficient thrust, pigs fly just fine. However, this is not
necessarily a good idea. It is hard to be sure where they are going
to land, and it could be dangerous sitting under them as they fly
overhead. (from RFC 1925)
