WebJan 18, 2024 · AEAD primitive (Authenticated Encryption with Associated Data) provides functionality of symmetric authenticated encryption. Implementations of this primitive are secure against adaptive chosen ciphertext attacks. When encrypting a plaintext one can optionally provide associated data that should be authenticated but not encrypted.

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. … marianopolis open house 2021
