Symmetric-key cryptography refers to encryption methods in which both the sender and receiver share the same key (or, less commonly, in which their keys are different, but related in an easily computable way). This was the only kind of encryption publicly known until June 1976. Symmetric key ciphers are implemented as either block ciphers or stream ciphers. … WebCryptographic operations for the purpose of data privacy (confidentiality) prevent an unauthorized person from reading a message. The following operations are included in data privacy: Encrypt and Decrypt The encrypt operation changes plaintext data into ciphertext through the use of a cipher algorithm and key.
