Python 使用 RSA 公钥加密数据

安装 pycryptodome 库

pip install pycryptodome

使用 RSA 公钥加密数据

import base64
from Crypto.Cipher import PKCS1_v1_5 as Cipher_pksc1_v1_5
from Crypto.PublicKey import RSA

def _encrpt(string, public_key):
    rsakey = RSA.importKey(public_key)  # 读取公钥
    cipher = Cipher_pksc1_v1_5.new(rsakey)
    # 因为encryptor.encrypt方法其内部就实现了加密再次Base64加密的过程，所以这里实际是通过下面的1和2完成了JSEncrypt的加密方法
    encrypt_text = cipher.encrypt(string.encode())  # 1.对账号密码组成的字符串加密
    cipher_text_tmp = base64.b64encode(encrypt_text)  # 2.对加密后的字符串base64加密
    return cipher_text_tmp.decode()

# 使用公钥加密
def gen_body(pwd, public_key=None):
    '''根据账号密码生成请求的body然后调用_encrpt方法加密'''
    if not public_key: public_key = '输入公钥'     # 输入对应的公钥
    key = '-----BEGIN PUBLIC KEY-----\n' + public_key + '\n-----END PUBLIC KEY-----'
    encrypt_res = _encrpt(pwd, key)
    return str_replace(encrypt_res)

# 文本替换
def str_replace(encoder):
    result = encoder.replace("+","-")
    result = result.replace("/","_")
    result = result.replace("=",",")
    return result

if __name__ == '__main__':
    PUBLIC_KEY = "MFwwDQYJKoZIhvcNAQEBBQADSwAwSAJBANunOZNi98lS7GiaUdnFJbzVy5oxsLqsTetCRfp2pE3sD3pWGBa1xjqrU/+9VtcJC6KvHel0IMSmlfoCxXvlKQkCAwEAAQ=="
    print(gen_body("这是 public 测试 password",PUBLIC_KEY)) #输入要加密的密码```

问题解决

• 报 ModuleNotFoundError: No module named 'Crypto' 错误
