A digital signature scheme typically consists of three algorithms: A key generation algorithm that selects a private key uniformly at random from a set of possible private keys. The algorithm outputs the private key and a corresponding public key. A signing algorithm that, given a message and a private key, produces a signature. A signature verifying algorithm that, given the message, public key and signature, either accepts or rejects the message's claim to authenticity.
