php加密=＞python解密或者python加密=＞php解密

本文基于AES-CBC加密解密方法

一、php加密=>python解密

php加密:

    $key = 'ABCDEFGHIJKLMNOP'; //16位
    $vi  = '0102030405060708'; //16位
    $str = '需加密的字符串';
    $sign = openssl_encrypt(str, 'AES-128-CBC', $key,  OPENSSL_RAW_DATA, $vi);
    $sign = base64_encode($sign);
    var_dump($sign);die();
    //结果：F8dIExttsNN1WK5BCLHhkRZVwVIoI70W1G+pjPhgNRk=

python解密:

import base64
import re
from Crypto.Cipher import AES

key = 'ABCDEFGHIJKLMNOP' #16位

def AES_Decrypt(data):
  vi   = '0102030405060708'#16位
  data = data.encode('utf8')
  encodebytes = base64.decodebytes(data)
  # 将加密数据转换位bytes类型数据
  cipher = AES.new(key.encode('utf8'), AES.MODE_CBC, vi.encode('utf8'))
  text_decrypted = cipher.decrypt(encodebytes)
  # 判断是否含有中文
  zhmodel = re.compile(u'[\u4e00-\u9fff]')
  match = zhmodel.search(text_decrypted.decode())
  if match == False:
      #无中文时补位
      unpad = lambda s: s[0:-s[-1]]
      text_decrypted = unpad(text_decrypted)
  text_decrypted = text_decrypted.decode('utf8').rstrip()#去掉补位的右侧空格
  return text_decrypted

print(AES_Decrypt("F8dIExttsNN1WK5BCLHhkRZVwVIoI70W1G+pjPhgNRk="))
#结果：需加密的字符串

二、python加密=>php解密

python加密:

import base64
import re
from Crypto.Cipher import AES

key = 'ABCDEFGHIJKLMNOP' #16位

def AES_Encrypt(data):
  vi = '0102030405060708'#16位
  cryptor = AES.new(key.encode('utf8'), AES.MODE_CBC, vi.encode('utf8'))
  # 判断是否含有中文
  zhmodel = re.compile(u'[\u4e00-\u9fff]')
  match = zhmodel.search(data)
  if match == None:
  	  #无中文时
      add = 16 - len(data) % 16
      pad = lambda s: s + add * chr(add)
      data = pad(data)
      enctext = cryptor.encrypt(data.encode('utf8'))
  else:
  	  #含有中文时
      data = data.encode()
      add = 16 - len(data) % 16
      data = data + add * (chr(add)).encode()
      enctext = cryptor.encrypt(data)
  encodestrs = base64.b64encode(enctext).decode('utf8')
  return encodestrs
 
print(AES_Encrypt('abcd123'))
#结果：KeAJB/1sMcGk6HUmKeC5jA==
#python解密可直接调用print(AES_Decrypt("KeAJB/1sMcGk6HUmKeC5jA=="))

php解密:

	key  = 'ABCDEFGHIJKLMNOP'; //16位
    $vi  = '0102030405060708';//16位

    $data = 'KeAJB/1sMcGk6HUmKeC5jA==';
    $sign = openssl_decrypt(base64_decode($data), 'AES-128-CBC', $key, 1, $vi);
    var_dump($sign);die();
    //结果：abcd123
