/* EME-OAEP as defined in RFC 2437 (PKCS #1 v2.0) */
/* See Victor Shoup, "OAEP reconsidered," Nov. 2000,
* <URL: http://www.shoup.net/papers/oaep.ps.Z>
* for problems with the security proof for the
* original OAEP scheme, which EME-OAEP is based on.
*
* Note that for RSA OAEP a security proof in the
* random oracle model *does* exist if 160 < log_2(N/e);
* cf. section 7.2 ("But RSA-OAEP with exponent 3 is
* provably secure") of Shoup's paper. (The slight
* differences between the OAEP definition used by Shoup
* and OAEP as defined in RFC 2437 should not affect
* this result.)
