[−][src]Module yogcrypt::sm2

An implementation of the SM2 signature standard.

Usage

extern crate yogcrypt;
use yogcrypt::sm2::{get_sec_key, get_pub_key, sm2_gen_sign, sm2_ver_sign};

let sk = get_sec_key();
let msg = b"Hello World!";

let pk = get_pub_key(sk);

let mut tag = sm2_gen_sign(msg, sk, pk);

let t = sm2_ver_sign(msg, pk, &tag);

// Signature is accepted
assert!(t);

Structs

Signature	A signature (tag) consists of two fields: `r` and `s`, each is a 256 bit number
U64x4	A 256-bit number represented using four `u64`'s.

Functions

get_pub_key	Compute public key from secret key
get_sec_key	Randomly sample secret key uniformly from [0,..n), where n is the order of the base point
sm2_gen_sign	Generate a valid signature for a message using a pair of keys.
sm2_ver_sign	Verify a signature on a given message using public key

Type Definitions

Coordinate	A coordinate is an element from the field with order `MODULO_P`.
PubKey	A public key is a point on the elliptic curve group.
SecKey	A secret key is an element from the field with order `MODULO_N`.
