The Algorithm type and four commonly used AEAD algorithms (AES-128-GCM, AES-256-GCM, ChaCha20-Poly1305 and XChaCha20-Poly1305).
The Algorithm.Stream method provides a way to create a Stream directly from a secret key instead of first creating an AEAD instance explicitly.
The NativeAES function in the sioutil. It allows users to determine whether an optimized (and constant time) implementation is available for their CPU.
Two helper functions (Random and MustRandom) for generating random bytes in sioutil.
