include Tezos_stdlib.Compare.S with type t := t
val (=) : t -> t -> bool

x = y iff compare x y = 0

val (<>) : t -> t -> bool

x <> y iff compare x y <> 0

val (<) : t -> t -> bool

x < y iff compare x y < 0

val (<=) : t -> t -> bool

x <= y iff compare x y <= 0

val (>=) : t -> t -> bool

x >= y iff compare x y >= 0

val (>) : t -> t -> bool

x > y iff compare x y > 0

val compare : t -> t -> int

compare an alias for the functor parameter's compare function

val equal : t -> t -> bool

equal x y iff compare x y = 0

val max : t -> t -> t

max x y is x if x >= y otherwise it is y

val min : t -> t -> t

min x y is x if x <= y otherwise it is y

type watermark = Stdlib.Bytes.t
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 generate_key : ?seed:Stdlib.Bytes.t -> unit -> Public_key_hash.t * Public_key.t * Secret_key.t
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 pop_verify : Public_key.t -> ?msg:Bls12_381_signature.MinPk.pk -> Stdlib.Bytes.t -> bool

pop_verify pk proof checks if proof is a valid proof of possesssion for pk (or msg is provided). If pk is not a BLS key, pop_verify pk _ = false.

val aggregate_check : (Public_key.t * watermark option * bytes) list -> t -> bool

aggregate_check pk_msg_list signature returns true if the signature is a valid aggregate signature of the signatures produced by signing message msg (with optional watermark) with the secret key of pk for each element (pk, watermark, msg) of the list pk_msg_list.

val aggregate_signature_opt : ?subgroup_check:bool -> t list -> t option

aggregate_signature_opt sig_list creates an aggregated signature using the list of signatures sig_list. If subgroup_check is set, the function also checks if the points are in the prime subgroup.

val aggregate_signature_weighted_opt : ?subgroup_check:bool -> (Z.t * t) list -> t option

aggregate_signature_weighted_opt [(w_1, s_1);(w_1, s_2);...] aggregates the signatures s_i multiplied by their weights w_i, i.e it returns the sum of w_i * s_i. Return None if deserialization of signatures fails. If subgroup_check is set, the function also checks if the points are in the prime subgroup.

val aggregate_public_key_opt : ?subgroup_check:bool -> Public_key.t list -> Public_key.t option

aggregate_public_key_opt ?subgroup_check pks aggregates the public keys pks. If subgroup_check is set, the function also checks if the points are in the prime subgroup.

val aggregate_public_key_weighted_opt : ?subgroup_check:bool -> (Z.t * Public_key.t) list -> Public_key.t option

aggregate_public_key_weighted_opt [(w_1, pk_1);(w_2, pk_2);...] aggregates the public keys pk_i multiplied by their weights w_i, i.e it returns the sum of w_i * pk_i. If subgroup_check is set, the function also checks if the points are in the prime subgroup.
