!!! Overview
[{$pagename}] is decribed in [RFC 7539]
[AEAD_CHACHA20_POLY1305] is an [Authenticated Encryption with Associated Data] [algorithm]. The inputs to [AEAD_CHACHA20_POLY1305] are:
* A 256-bit key
* A 96-bit [nonce] -- different for each invocation with the same key
* An arbitrary length plaintext
* Arbitrary length additional authenticated data ([AAD])
Some protocols may have unique per-invocation inputs that are not 96
bits in length. For example, IPsec may specify a 64-bit nonce. In
such a case, it is up to the protocol document to define how to
transform the protocol nonce into a 96-bit nonce, for example, by
concatenating a constant value.
The [ChaCha20] and [Poly1305] [Cryptographic Primitives] are combined into an [Authenticated Encryption with Associated Data]
