# RustCrypto: Authenticated Encryption with Associated Data (AEAD) Algorithms

[![Dependency Status][deps-image]][deps-link]
[![Project Chat][chat-image]][chat-link]

Collection of [Authenticated Encryption with Associated Data (AEAD)][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.
