Crate aead

Authenticated Encryption with Associated Data (AEAD) traits

This crate provides an abstract interface for AEAD ciphers, which guarantee both confidentiality and integrity, even from a powerful attacker who is able to execute chosen-ciphertext attacks. The resulting security property, ciphertext indistinguishability, is considered a basic requirement for modern cryptographic implementations.

See RustCrypto/AEADs for cipher implementations which use this trait.

Payload

AEAD payloads are a combination of a message (plaintext or ciphertext) and “additional associated data” (AAD) to be authenticated (in cleartext) along with the message.
