In public-key cryptography, Edwards-curve Digital Signature Algorithm (EdDSA) is a digital signature scheme using a variant of Schnorr signature based on twisted Edwards curves. It is designed to be faster than existing digital signature schemes without sacrificing security. It was developed by a team including Daniel J. Bernstein, Niels Duif, Tanja Lange, Peter Schwabe, and Bo-Yin Yang. The reference implementation is public-domain software.
Ed25519
Ed25519 is one of the implementations of EdDSA (Edwards‑curve Digital Signature Algorithm), an elliptic-curve digital signature algorithm designed with security and performance in mind. It uses a twisted Edwards curve from the Curve25519 family and, combined with the SHA‑512 hash function, provides fast signing (sign) and verification (verification).
