ed25519 Algorithm

In public-key cryptanalysis, Edwards-curve digital signature Algorithm (EdDSA) is a digital signature scheme use a variant of Schnorr signature based on twisted Edwards curves. It was developed by a team including Daniel J. Bernstein, Niels Duif, Tanja Lange, Peter Schwabe, and Bo-Yin Yang.

ed25519 source code, pseudocode and analysis

Ed25519 is intended to supply attack resistance comparable to quality 128-bit symmetric ciphers. The Bernstein team has optimized Ed25519 for the x86-64 Nehalem/
