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.
