python和java使用AES加密算法加密字符串得到加密后的加密串不一样

#!/usr/bin/env python

# -*- coding: utf-8 -*-



from Crypto.Cipher import AES

import base64

import os



BLOCK_SIZE = 16

PADDING = '\0'

pad_it = lambda s: s+(16 - len(s)%16)*PADDING

key = b'B31F2A75FBF94099'

iv = b'1234567890123456'



#使用aes算法，进行加密解密操作

#为跟java实现同样的编码，注意PADDING符号自定义

def encrypt_aes(sourceStr):

    generator = AES.new(key, AES.MODE_CFB, iv)

    crypt = generator.encrypt(pad_it(sourceStr).encode('utf-8'))

    cryptedStr = base64.b64encode(crypt)

    return cryptedStr



def decrypt_aes(cryptedStr):

    generator = AES.new(key, AES.MODE_CFB, iv)

    cryptedStr = base64.b64decode(cryptedStr)

    recovery = generator.decrypt(cryptedStr)

    decryptedStr = recovery.rstrip(PADDING.encode('utf-8'))

    return decryptedStr



sourceStr = '{"abc":"dfr","agh":"fdfd"}'





print('明文:',sourceStr)

print('加密串:',encrypt_aes(sourceStr))

print('解密串:',decrypt_aes(encrypt_aes(sourceStr)).decode('utf-8'))



python运行结果:



明文: 你好

加密串: b'bYywQggIyUep1a55IRMe2Au0xGw='

解密串: 你好
