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.

Re-exports

• pub use generic_array;
• pub use crypto_common::rand_core;

Modules

• consts
  Type aliases for many constants.

Macros

• impl_decrypt_in_place 🔒
