Python implementation gm algorithm
Project description
- SM2
gm signature a. generate keypair
>>> from pysmx.SM2 import generate_keypair >>> pk, sk = generate_keypair()
signature
>>> from pysmx.SM2 import Sign >>> len_para = 64 >>> sig = Sign("hello", sk, '12345678abcdef', len_para)
verify
>>> from pysmx.SM2 import Verify >>> len_para = 64 >>> Verify(sig, "hello", pk, len_para)
encrpto
>>> from pysmx.SM2 import Encrypt >>> e = b'hello' >>> len_para = 64 >>> C = Encrypt(e, pk, len_para, 0) # 0 means var e is not a hex string
decrpto
>>> from pysmx.SM2 import Decrypt >>> len_para = 64 >>> m = Decrypt(C, sk, len_para)
- SM3
hash a. method 1:
>>> from pysmx.SM3 import SM3 >>> sm3 = SM3() >>> sm3.update('abc') >>> sm3.hexdigest()
method 2:
>>> from pysmx.SM3 import hash_msg >>> s = 'abc' >>> hash_msg(s)
- SM4
block encrpto a. encrpto
>>> from pysmx.SM4 import Sm4, ENCRYPT, DECRYPT >>> key_data = b'hello word errrr...' # 16 bytes at least >>> sm4 = Sm4() >>> input_data = [1,2,3] >>> sm4.sm4_set_key(key_data, ENCRYPT) >>> msg = sm4.sm4_crypt_ecb()
decryto
>>> from pysmx.SM4 import Sm4, ENCRYPT, DECRYPT >>> key_data = b'hello word errrr...' # 16 bytes at least >>> sm4 = Sm4() >>> sm4.sm4_set_key(key_data, DECRYPT) >>> sm4.sm4_crypt_ecb(msg)
