val compare : t -> t -> int

compare an alias for the functor parameter's compare function

val sign : ?watermark:watermark -> Secret_key.t -> Stdlib.Bytes.t -> t

sign ?watermark sk message produce the signature of message (with possibly watermark) using sk.

val check : ?watermark:watermark -> Public_key.t -> t -> Stdlib.Bytes.t -> bool

check pk ?watermark signature message check that signature is the signature produced by signing message (with possibly watermark) with the secret key of pk.

val deterministic_nonce : Secret_key.t -> Stdlib.Bytes.t -> Stdlib.Bytes.t

deterministic_nonce sk msg returns a nonce that is determined by sk and msg

val deterministic_nonce_hash : Secret_key.t -> Stdlib.Bytes.t -> Stdlib.Bytes.t

deterministic_nonce_hash sk msg returns the BLAKE2b hash of a nonce that is determined by sk and msg.

In other words, Blake2b.digest (deterministic_nonce sk msg) = deterministic_nonce_hash sk msg

val append : ?watermark:watermark -> secret_key -> Stdlib.Bytes.t -> Stdlib.Bytes.t

append sk buf is the concatenation of buf and the serialization of the signature of buf signed by sk.

val concat : Stdlib.Bytes.t -> t -> Stdlib.Bytes.t

concat buf t is the concatenation of buf and the serialization of t.
