This document defines the ChaCha20 stream cipher as well as the use
of the Poly1305 authenticator, both as stand-alone algorithms and as
a "combined mode", or Authenticated Encryption with Associated Data
(AEAD) algorithm.

RFC 7539, the predecessor of this document, was meant to serve as a
stable reference and an implementation guide.  It was a product of
the Crypto Forum Research Group (CFRG).  This document merges the
errata filed against RFC 7539 and adds a little text to the Security
Considerations section.

This document is a product of the Crypto Forum Research Group of the IRTF.
