1. SM2

国密公钥加解密签名验签

1. 密钥生成

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

1. 签名

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

1. 验签

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

1. 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

1. 解密

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

1. SM3

国密哈希 a. 方法1:

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

1. 方法2:

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

1. 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()

2. 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)
