comment Digital Signature with Encryption
@LiorOhana - Digital signature schemes are in part intended to permit others to authenticate the message is from you, and has not been altered. If you are trying to prove to yourself that nothing has changed, there's not really any need for a digital signature at all - simply store the hash. Obviously the hash must be stored in such a way that a potential attacker cannot modify, but the same requirement holds true for the private key in a digital signature scheme, so you must already have the ability to do this.

comment inverse of 985 mod(φ60131)
@Thomas Since this algorithm is fundamental to the operation of RSA, crypto seems like a reasonable location. I believe it was originally tagged with "homework", so I assume this is some sort of assignment to demonstrate breaking of RSA by factoring the public key.
