tongsuo-python-sdk

Tongsuo-Python-SDK基于Tongsuo密码库, 为Python应用提供密码学原语和安全传输协议的支持，目前以支持中国商用密码算法和安全协议为主。

SM2签名和验签，详见sm2_sign_verify.py

from tongsuopy.crypto import hashes, serialization from tongsuopy.crypto.asymciphers import ec msg = b"hello" key = ec.generate_private_key(ec.SM2()) pem = key.public_key().public_bytes( encoding=serialization.Encoding.PEM, format=serialization.PublicFormat.SubjectPublicKeyInfo, ) pubkey = serialization.load_pem_public_key(pem) signature = key.sign(msg, ec.ECDSA(hashes.SM3())) pubkey.verify(signature, msg, ec.ECDSA(hashes.SM3()))

SM2加密和解密，详见sm2_encrypt_decrypt_from_pem.py

from tongsuopy.crypto import serialization from tongsuopy.crypto.asymciphers import ec msg = b"hello" key = ec.generate_private_key(ec.SM2()) pem = key.public_key().public_bytes( encoding=serialization.Encoding.PEM, format=serialization.PublicFormat.SubjectPublicKeyInfo, ) pubkey = serialization.load_pem_public_key(pem) ciphertext = pubkey.encrypt(msg) decrypt_text = key.decrypt(ciphertext) assert decrypt_text == msg

SM3杂凑，详见sm3.py

from tongsuopy.crypto import hashes h = hashes.Hash(hashes.SM3()) h.update(b"abc") res = h.finalize()

SM4-CBC加密，详见sm4_cbc.py

from tongsuopy.crypto.ciphers import Cipher, algorithms, modes c = Cipher(algorithms.SM4(key), modes.CBC(iv)) enc = c.encryptor() ciphertext = enc.update(plaintext) ciphertext += enc.finalize()

SM4-GCM加密，详见sm4_gcm.py

from tongsuopy.crypto.ciphers import Cipher, algorithms, modes c = Cipher(algorithms.SM4(key), modes.GCM(iv)) enc = c.encryptor() enc.authenticate_additional_data(aad) ciphertext = enc.update(plaintext) ciphertext += enc.finalize() 安装 pip install tongsuopy

要求Python >= 3.6。

功能特性支持SM2加密和解密支持SM2签名和验签支持SM3杂凑算法支持SM4加解密，包括ECB、CBC、OFB、CFB、CTR模式支持SM4-GCM和SM4-CCM [TODO] TLCP协议支持交流群
