[cryptography] RSA signatures without padding

2015-07-10 Thread Filip Paun
Suppose I have a message M for which I generate an RSA-2048 digital signature as follows: H = SHA-256(M) S = H^d mod N Assume N = p*q is properly generated and d is the RSA private key. And I verify the signature as follows: S^e mod N == H' where H' is the SHA-256 of the message to be
