-/*----- Notes on OAEP -----------------------------------------------------*
- *
- * Applying OAEP before RSA encryption renders the construction plaintext-
- * aware under the random oracle model. This is probably a good thing. OAEP
- * was designed by Bellare and Rogaway. This particular variant is the one
- * specified in PKCS#1 version 2.0. It's apparently not compatible with the
- * OAEP used in the SET protocols.
