EdDSA for more curves
Daniel J. Bernstein and Simon Josefsson and Tanja Lange and Peter Schwabe and Bo-Yin Yang
Abstract
The original specification of EdDSA was suitable only for finite fields Fq with q mod 4 = 1. The main purpose of this document is to extend EdDSA to allow finite fields Fq with any odd q. This document also extends EdDSA to support prehashing, i.e., signing the hash of a message.
