前言:接口中上次的手机号码和密码是传入的加密的,模拟自动化的时候也需要先对数据进行加密
- 1.各种语言实现
网上已经各种语言实现好的AES加密,可以点击查看:http://outofmemory.cn/code-snippet/35524/AES-with-javascript-java-csharp-python-or-php
- 2.python实现时踩的坑
(1)iv的使用,必须使用;
(2)iv的正确使用,格式:’\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0’;
(3)最后要解析成base64.b64encode;
(4)根据需求进行设置加密模式与密钥长度。
代码操作
# coding=utf-8 import hashlib from Crypto.Cipher import AES import base64 class AesCrypter(object): def __init__(self): self.key = b'********' self.iv = b'\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0' def encrypt(self, data): data1 = self.pkcs7padding(data) data = bytes(data1, encoding="utf8") # 传进来的参数先变成字节 h_key = hashlib.sha256(self.key).digest() cipher = AES.new(h_key, AES.MODE_CBC, self.iv) encrypted = cipher.encrypt(data) return base64.b64encode(encrypted) def decrypt(self, data): data = base64.b64decode(data) h_key = hashlib.sha256(self.key).digest() cipher = AES.new(h_key, AES.MODE_CBC, self.iv) decrypted = cipher.decrypt(data) decrypted = self.pkcs7unpadding(decrypted) return decrypted def pkcs7padding(self, data): # AES.block_size 16位 bs = AES.block_size padding = bs - len(data) % bs # 16-11%16 padding_text = chr(padding) * padding # chr()返回当前正是对应的ascii码 return data + padding_text def pkcs7unpadding(self, data): lengt = len(data) unpadding = data[lengt - 1] return data[0:lengt - unpadding] def sha(self, text): # key进行256哈希 sha256 = hashlib.sha256() sha256.update(text.encode('utf-8')) res = sha256.hexdigest() return res if __name__ == '__main__': aes = AesCrypter() encrypted = aes.encrypt('39999912332') # 加密 print(encrypted) plain = aes.decrypt(encrypted) # 解密 print(plain)
运行后的结果
