The
crypto_ed25519_sign() and
crypto_ed25519_check() 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 and security considerations are the same as those described in
crypto_sign(3monocypher).
An incremental interface is available; see
crypto_ed25519_sign_init_first_pass(3monocypher).
crypto_ed25519_public_key() and
crypto_ed25519_sign() return nothing.
crypto_ed25519_check() returns 0 for legitimate
messages and -1 for forgeries.

These functions implement Ed25519 as described in RFC 8032.
The
crypto_ed25519_sign(),
crypto_ed25519_check(), and
crypto_ed25519_public_key() functions appeared in
Monocypher 3.0.0. They replace recompilation of Monocypher with the
ED25519_SHA512 preprocessor
definition.
