Alice's digital signature, S, is the pair (r, s). Alice sends the message M and her digital signature S to Bob. Example of DSA Verification by Bob. Bob receives Alice's message, M, and the digital signature S.

WebApr 21, 2024 · Cryptography is a form of securing digital data and messages often using special keys that only the sender and recipient have access to. Cryptography uses mathematical systems and algorithms to encrypt and decrypt data. Symmetrical cryptography uses the same key for both encryption and decryption.
