Sourceval sign : ?watermark:watermark -> Secret_key.t -> Bytes.t -> t

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

Sourceval check : ?watermark:watermark -> Public_key.t -> t -> 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.

Sourceval deterministic_nonce : Secret_key.t -> Bytes.t -> Bytes.t

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

Sourceval deterministic_nonce_hash : Secret_key.t -> Bytes.t -> 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

Sourcetype splitted = {

A splitted signature is a binary representation of a signature with a fixed 64 bytes suffix and a possible prefix.

Sourceval split_signature : t -> splitted

split_signature s splits the signature s into {prefix; suffix} where suffix is the fixed 64 bytes suffix of s and prefix are the remaining preceding bytes if any.

Encoding for signature prefixes.

Sourceval append : ?watermark:watermark -> secret_key -> Bytes.t -> Bytes.t

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

Sourceval size : t -> int

The size of the signature in bytes. Can be 64 for Ed25519, Secp256k1 and P256 signatures or 96 for BLS signatures.

Sourceval of_secp256k1 : Tezos_crypto__.Secp256k1.t -> t

of_secp256k1 s returns a wrapped version of the Secp256k1 signature s in t.

Sourceval of_ed25519 : Tezos_crypto__.Ed25519.t -> t

of_ed25519 s returns a wrapped version of the Ed25519 signature s in t.

Sourceval of_p256 : Tezos_crypto__.P256.t -> t

of_p256 s returns a wrapped version of the P256 signature s in t.

of_bls s returns a wrapped version of the BLS signature s in t.

Sourcetype algo = Signature.V_latest.algo =
  1. | Ed25519
  2. | Secp256k1
  3. | P256
  4. | Bls

The type of signing algorithms.

Sourceval algos : algo list

The list of signing algorithm supported, i.e. all constructors of type algo.

Sourceval generate_key : ?algo:algo -> ?seed:Bytes.t -> unit -> public_key_hash * public_key * secret_key

generate_key ~algo ~seed () generates a key pair for the signing algorithm algo from the random seed seed.

Sourcemodule Of_V_latest : sig ... end

Converting from signatures of V_latest to V_latest. This module implements conversions which are the identity, so total, but we keep the signature as CONV_OPT for compatibility with V0.Of_V_latest and V1.Of_V_latest and to ease snapshotting.

Sourcemodule Of_V0 : sig ... end

Converting from signatures of V0 to V_latest.

Sourcemodule Of_V1 : sig ... end

Converting from signatures of V1 to V_latest.
