An EdDSA Secret key
Modulecryptonite-0.30Haskell2010
Crypto.PubKey.EdDSA
EdDSA signature generation and verification, implemented in Haskell and parameterized with elliptic curve and hash algorithm. Only edwards25519 is supported at the moment.
The module provides "context" and "prehash" variants defined in RFC 8032.
This implementation is most useful when wanting to customize the hash algorithm. See module Crypto.PubKey.Ed25519 for faster Ed25519 with SHA-512.
