-/*----- Notes on the RC5 block cipher -------------------------------------*
- *
- * RC5 was designed by Ron Rivest as a test vehicle for the use of data-
- * dependent rotations in cryptographic transformations.  The algorithm is
- * covered by a patent held by RSA Security Inc. (US Patent# 5,724,428).
- * It's vulnerable to some clever differential attacks, which can break it in
- * about %$2^{44}$% chosen plaintexts.  I don't recommend the use of this
- * cipher.
