This memo specifies two prime-order groups, ristretto255 and
decaf448, suitable for safely implementing higher-level and complex
cryptographic protocols. The ristretto255 group can be implemented
using Curve25519, allowing existing Curve25519 implementations to be
reused and extended to provide a prime-order group. Likewise, the
decaf448 group can be implemented using edwards448.
This document is a product of the Crypto Forum Research Group (CFRG)
in the IRTF.
