SM2加签验签加密解密方法

问题：SM2加解签如何使用？

方法：

import base64
import binascii
from gmssl import sm2, func
#16进制的公钥和私钥
private_key = '00B9AB0B828FF68872F21A837FC303668428DEA11DCD1B24429D0C99E24EED83D5'
public_key = 'B9C9A6E04E9C91F7BA880429273747D7EF5DDEB0BB2FF6317EB00BEF331A83081A6994B8993F3F5D6EADDDB81872266C87C018FB4162F5AF347B483E24620207'
sm2_crypt = sm2.CryptSM2(
    public_key=public_key, private_key=private_key)

加密 解密

#数据和加密后数据为bytes类型
data = b"111"
enc_data = sm2_crypt.encrypt(data)
dec_data =sm2_crypt.decrypt(enc_data)
assert dec_data == data

加签 验签

data = b"111" # bytes类型
random_hex_str = func.random_hex(sm2_crypt.para_len)
sign = sm2_crypt.sign(data, random_hex_str) #  16进制
assert sm2_crypt.verify(sign, data) #  16进制
