Detailed Description

Type declarations and APIs for the Ed25519 algorithm.

Ed25519 is a specific implementation of EdDSA, a digital signature scheme. EdDSA is based on Twisted Edwards curves and is designed to be faster than existing digital signature schemes without sacrificing security. It was developed by Daniel J. Bernstein, et al. Ed25519 is intended to provide attack resistance comparable to quality 128-bit symmetric ciphers.
