RustCrypto: Authenticated Encryption with Associated Data (AEAD) Algorithms

Collection of Authenticated Encryption with Associated Data (AEAD) algorithms written in pure Rust.

AEADs are high-level symmetric encryption primitives which defend against a wide range of potential attacks (i.e. IND-CCA3).

Usage

Crates functionality is expressed in terms of traits defined in the aead crate.

Crates

Name	Algorithm	Crates.io	Documentation	Build
aes-gcm	AES-GCM
aes-gcm-siv	AES-GCM-SIV
aes-siv	AES-SIV
chacha20poly1305	(X)ChaCha20Poly1305
crypto_box	Curve25519XSalsa20Poly1305
xsalsa20poly1305	XSalsa20Poly1305

NOTE: the aes-ccm crate also implements the aead traits used by all of the other crates in this repository.

Minimum Supported Rust Version

All crates in this repository support Rust 1.40 or higher. In future minimum supported Rust version can be changed, but it will be done with the minor version bump.
