Which RSA algorithm? RSA encryption does not require a message digest algorithm. The RSA signature algorithm usually uses message digest algorithms for efficiency and for a few other reasons. However, the RSA encryption and decryption algorithms are inverses of each other so one could make a signature by applying RSA decryption to a message text. Only the person having the private key is capable of doing this! The recipient would then apply RSA encryption (since the public key is public!) to read the message and if this works then it verifies the sender as well! > RSA is basically an implementation of this concept a^b^c = a ^c^b = > a^bc with modulo N thrown in. I think you are confusing the Diffie-Hellman key exchange with RSA.
