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 -> Tezos_crypto.Signature.Secp256k1.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 sign_keccak256 : Secret_key.t -> bytes -> t

Signs the Keccak256 hash of bytes, instead of BLAKE2b.

val check_keccak256 : Public_key.t -> t -> bytes -> bool

Check the Keccak256 hash of bytes, instead of BLAKE2b.

val recover : bytes -> bytes -> (bytes, string) Stdlib.result

recover_caller signature msg recovers the caller of signature signature on message msg. The "caller" in this context is the rightmost 160-bits of the Keccak-256 hash of the corresponding ECDSA public key.

val eth_address_of_public_key : Public_key.t -> bytes

eth_address_of_public_key pk computes the Ethereum address of an Externally Owned Account (EOA) using this public key.
