安装:

pip 安装

pip install snowland-smx

或者

源码安装 python setup.py install

  1. SM2

国密公钥加解密签名验签

a. 密钥生成

from pysmx.SM2 import generate_keypair
pk, sk = generate_keypair()

签名

from pysmx.SM2 import Sign
len_para = 64
sig = Sign("你好", sk, '12345678abcdef', len_para)

验签

from pysmx.SM2 import Verify
len_para = 64
Verify(sig, "你好", pk, len_para)

加密

from pysmx.SM2 import Encrypt
e = b'hello'
len_para = 64
C = Encrypt(e, pk, len_para, 0)  # 此处的1代表e是否是16进制字符串

解密

from  pysmx.SM2 import Decrypt
len_para = 64
m = Decrypt(C, sk, len_para)

SM3

国密哈希 a. 方法1:

from pysmx.SM3 import SM3
sm3 = SM3()
sm3.update('abc')
sm3.hexdigest()

b. 方法2:

from pysmx.SM3 import hash_msg
s = 'abc'
hash_msg(s)

SM4

国密私钥加解密 a. 加密

from pysmx.SM4 import Sm4, ENCRYPT, DECRYPT
key_data = b'hello word errrr...'  # 至少16字节
sm4 = Sm4()
input_data = [1,2,3]
sm4.sm4_set_key(key_data, ENCRYPT)
msg = sm4.sm4_crypt_ecb()

b. 解密

from pysmx.SM4 import Sm4, ENCRYPT, DECRYPT
key_data = b'hello word errrr...'  # 至少16字节
sm4 = Sm4()
sm4.sm4_set_key(key_data, DECRYPT)
sm4.sm4_crypt_ecb(msg)
