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).

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

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

All crates in this repository support Rust 1.41 or higher. In future minimum supported Rust version can be changed, but it will be done with the minor version bump.
