Detailed Description

Ed25519ph algorithm, used for EdDSA with pre-hashing.

Ed25519ph is a specific implementation of EdDSA, a digital signature scheme with prehashing. 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. Ed25519ph is intended to provide attack resistance comparable to quality 128-bit symmetric ciphers.
