WebJun 16, 2024 · The receiver takes as input the signature and with the public key ( sent with the message) verify it using verification algorithm and produce the hash as output. According to what I understand, the receiver performs the revere action, which is equivalent to encryption /decryption, using private/public key instead of the same private key. A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents. A valid digital signature, where the prerequisites are satisfied, gives a recipient very high confidence that the message was created by a known sender (authenticity), and that the message was not altered in transit (integrity).
