These functions provide Ed25519 public key signatures and verification with SHA-512 as the underlying hash function. They are interoperable with other Ed25519 implementations. If you have no interoperability requirements, prefer crypto_sign(3monocypher).
The arguments, security considerations, and semantics are the same as those described in crypto_sign_init_first_pass(3monocypher) and crypto_sign(3monocypher).
