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.

Modules

consts

Type aliases for many constants.

devdev

Development-related functionality

streamstream

Streaming AEAD support.

Macros

impl_decrypt_in_place

Implement the decrypt_in_place method on AeadInPlace and [AeadMutInPlace], using a macro to gloss over the &self vs &mut self.

new_testdev

Define AEAD test

Structs

Error

Error type.

Payloadalloc

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.
