comparison dcrypt/crypto/ciphers/RC6.d @ 1:483e4467b5f6

Find changesets by keywords (author, files, the commit message), revision number or hash, or revset expression.
Added Blowfish with test vectors. Minor cleanup of other cipher classes (should probably clean more). Continued work on high-level cipher API (didn't get very far).
