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).
For an incremental interface, 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.
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.
