aes-cbc-pkcs7padding-'s Introduction

AES/CBC/PKCS7Padding加密的实现

一些情况下，客户端要与服务端通信会加密。常会要到加密算法AES(Advanced Encryption Standard)，下面是Python和PHP的实现。

Python需要安Crypto库(pip install pycrypto或访问https://pypi.python.org/pypi/pycrypto)

PHP需要安装mcrypt扩展

说明

加密模式采用AES/CBC/PKCS7Padding

注意：加密后的字节码使用Base64转换成字符串

  • 加密模式: CBC
  • 填充模式: PKCS7Padding
  • 加密密钥: 用户密钥 SHA256 的32 bytes
  • AES IV : 加密密钥的前 16 bytes
  • Base 64: Base64.DEFAULT

加密过程:

加密：padding->CBC加密->base64编码

解密：base64解码->CBC解密->unpadding

AES加密结果基准测试:
