Overview
️🔧 BlueKing crypto-python-sdk 是一个基于 pyCryptodome / tongsuopy 等加密库的轻量级密码学工具包,为 Python 应用统一的加解密实现,
便于项目在不同的加密方式之间进行无侵入切换
Features
- [Basic] 提供加密统一抽象层,对接 Cryptodome / tongsuopy 等加密库,提供统一的加解密实现
- [Basic] 支持国际主流密码学算法:AES、RSA
- [Basic] 支持中国商用密码学算法:SM2、SM4
- [Basic] 非对称加密支持 CBC、CTR、GCM、CFB 作为块密码模式
- [Contrib] Django Support,集成 Django settings、ModelField
Getting started
Installation
$ pip install bk-crypto-python-sdk
Usage
更多用法参考:使用文档
1. 基础用法
非对称加密
from bkcrypto import constants
from bkcrypto.asymmetric import options
from bkcrypto.asymmetric.ciphers import BaseAsymmetricCipher
from bkcrypto.contrib.basic.ciphers import get_asymmetric_cipher
asymmetric_cipher: BaseAsymmetricCipher = get_asymmetric_cipher(
cipher_type=constants.AsymmetricCipherType.SM2.value,
cipher_options={
constants.AsymmetricCipherType.SM2.value: options.SM2AsymmetricOptions(
private_key_string=None
),
constants.AsymmetricCipherType.RSA.value: options.SM2AsymmetricOptions(
private_key_string=None
),
}
)
assert "123" == asymmetric_cipher.decrypt(asymmetric_cipher.encrypt("123"))
assert asymmetric_cipher.verify(plaintext="123", signature=asymmetric_cipher.sign("123"))
对称加密
import os
from bkcrypto import constants
from bkcrypto.symmetric.ciphers import BaseSymmetricCipher
from bkcrypto.contrib.basic.ciphers import get_symmetric_cipher
symmetric_cipher: BaseSymmetricCipher = get_symmetric_cipher(
cipher_type=constants.SymmetricCipherType.SM4.value,
common={"key": os.urandom(16)},
)
assert "123" == symmetric_cipher.decrypt(symmetric_cipher.encrypt("123"))
2. 结合 Django 使用
在 Django Settings 中配置加密算法类型
from bkcrypto import constants
BKCRYPTO = {
"ASYMMETRIC_CIPHER_TYPE": constants.AsymmetricCipherType.SM2.value,
"SYMMETRIC_CIPHER_TYPE": constants.SymmetricCipherType.SM4.value,
}
非对称加密
from bkcrypto.asymmetric.ciphers import BaseAsymmetricCipher
from bkcrypto.contrib.django.ciphers import get_asymmetric_cipher
asymmetric_cipher: BaseAsymmetricCipher = get_asymmetric_cipher()
assert "123" == asymmetric_cipher.decrypt(asymmetric_cipher.encrypt("123"))
assert asymmetric_cipher.verify(plaintext="123", signature=asymmetric_cipher.sign("123"))
对称加密
from bkcrypto.symmetric.ciphers import BaseSymmetricCipher
from bkcrypto.contrib.django.ciphers import get_symmetric_cipher
symmetric_cipher: BaseSymmetricCipher = get_symmetric_cipher()
assert "123" == symmetric_cipher.decrypt(symmetric_cipher.encrypt("123"))
3. 使用 Django CipherManager
在 Django Settings 中配置加密算法类型
from bkcrypto import constants
from bkcrypto.symmetric.options import AESSymmetricOptions, SM4SymmetricOptions
from bkcrypto.asymmetric.options import RSAAsymmetricOptions, SM2AsymmetricOptions
BKCRYPTO = {
"ASYMMETRIC_CIPHER_TYPE": constants.AsymmetricCipherType.SM2.value,
"SYMMETRIC_CIPHER_TYPE": constants.SymmetricCipherType.SM4.value,
"SYMMETRIC_CIPHERS": {
"default": {
"common": {"key": "your key"},
"cipher_options": {
constants.SymmetricCipherType.AES.value: AESSymmetricOptions(key_size=16),
constants.SymmetricCipherType.SM4.value: SM4SymmetricOptions(mode=constants.SymmetricMode.CTR)
}
},
},
"ASYMMETRIC_CIPHERS": {
"default": {
"common": {"public_key_string": "your key"},
"cipher_options": {
constants.AsymmetricCipherType.RSA.value: RSAAsymmetricOptions(
padding=constants.RSACipherPadding.PKCS1_v1_5
),
constants.AsymmetricCipherType.SM2.value: SM2AsymmetricOptions()
},
},
}
}
非对称加密
使用 asymmetric_cipher_manager
获取 BKCRYPTO.ASYMMETRIC_CIPHERS
配置的 cipher
from bkcrypto.asymmetric.ciphers import BaseAsymmetricCipher
from bkcrypto.contrib.django.ciphers import asymmetric_cipher_manager
asymmetric_cipher: BaseAsymmetricCipher = asymmetric_cipher_manager.cipher(using="default")
assert "123" == asymmetric_cipher.decrypt(asymmetric_cipher.encrypt("123"))
assert asymmetric_cipher.verify(plaintext="123", signature=asymmetric_cipher.sign("123"))
对称加密
使用 symmetric_cipher_manager
获取 BKCRYPTO.SYMMETRIC_CIPHERS
配置的 cipher
from bkcrypto.symmetric.ciphers import BaseSymmetricCipher
from bkcrypto.contrib.django.ciphers import symmetric_cipher_manager
symmetric_cipher: BaseSymmetricCipher = symmetric_cipher_manager.cipher(using="default")
assert "123" == symmetric_cipher.decrypt(symmetric_cipher.encrypt("123"))
Django ModelField
from django.db import models
from bkcrypto.contrib.django.fields import SymmetricTextField
class IdentityData(models.Model):
password = SymmetricTextField("密码", blank=True, null=True)
