WebFeb 6, 2024 · RSA-OAEP consists of RSAEP((n, e), EME-OAEP(n, M))) instead, where EME-OAEP(n, M) performs the padding. Here M is the input message as octet string and m is the padded message.. Now as m can be any value in textbook RSA, it follows that the result of m = RSAEP((n, e), M) is a strict subset of the input of textbook RSA. That … OAEP is a fairly complicated construction with two different hash functions as parameters. The Cipher transform string lets you specify one of these, which you have specified as SHA-256. However, the MGF1 function also is parameterized by a hash function which you cannot specify in the cipher transformation string.
