Module secp256k1 

This module contains an implementation of the ECDSA signature scheme over the secp256k1 curve.

Messages can be signed and the signature can be verified again:

Example

use rand::thread_rng;
let kp = Secp256k1KeyPair::generate(&mut thread_rng());
let message: &[u8] = b"Hello, world!";
let signature = kp.sign(message);
assert!(kp.public().verify(message, &signature).is_ok());

Structs

Secp256k1KeyPair

Secp256k1 public/private key pair.

Secp256k1PrivateKey

Secp256k1 private key.

Secp256k1PublicKey

Secp256k1 public key.

Secp256k1Signature

Secp256k1 ECDSA signature.

Constants

SECP256K1_KEYPAIR_LENGTH

The key pair bytes length is the same as the private key length. This enforces deserialization to always derive the public key from the private key.

SECP256K1_PRIVATE_KEY_LENGTH

The length of a private key in bytes.

SECP256K1_PUBLIC_KEY_LENGTH

The length of a public key in bytes.

SECP256K1_SIGNATURE_LENGTH

The length of a signature in bytes.

Statics

SECP256K1

Type Aliases

DefaultHash

Default hash function used for signing and verifying messages unless another hash function is specified using the with_hash functions.
