WebFeb 14, 2024 · DSA stands for Digital Signature Algorithm. It is a cryptographic algorithm used to generate digital signatures, authenticate the sender of a digital message, and prevent message tampering. DSA works by having two keys: a private key owned by the sender and a public key held by the receiver. WebIntroduction to Symmetric Key Encryption.
