PHP的openssl AES转换为Python AES

我有一个如下的php文件:

I have a php file which is as follow:

$encryption_encoded_key = 'c7e1wJFz PBwQix80D1MbIwwOmOceZOzFGoidzDkF5g=';

function my_encrypt($data, $key) {
    $encryption_key = base64_decode($key);
    $iv = openssl_random_pseudo_bytes(openssl_cipher_iv_length('aes-256-cfb'));

    $encrypted = openssl_encrypt($data, 'aes-256-cfb', $encryption_key, 1, $iv);

    // The $iv is just as important as the key for decrypting, so save it with encrypted data using a unique separator (::)
    return base64_encode($encrypted . '::' . $iv);
}

function my_decrypt($data, $key) {
    // Remove the base64 encoding from key
    $encryption_key = base64_decode($key);

    // To decrypt, split the encrypted data from IV - unique separator used was "::"
    list($encrypted_data, $iv) = explode('::', base64_decode($data), 2);

    return openssl_decrypt($encrypted_data, 'aes-256-cfb', $encryption_key, 1, $iv);
}

$data = 'USER_ID||NAME||EMAIL||MOBILE';
$data_encrypted = my_encrypt($data, $encryption_encoded_key);
echo $data_encrypted;
$data_decrypted = my_decrypt($data_encrypted, $encryption_encoded_key);
echo "Decrypted string: ". $data_decrypted;

这很好用，并且能够使用加密密钥进行加密/解密，现在我也有一个python文件:

This works fine, and is able to encrypt/decrypt with the encryption key, now i also have a python file:

import hashlib
import base64
from Crypto.Cipher import AES
from Crypto import Random

encryption_encoded_key = 'c7e1wJFz PBwQix80D1MbIwwOmOceZOzFGoidzDkF5g='

def my_encrypt(data, key):
    #Remove the base64 encoding from key
    encryption_key = base64.b64decode(key)
    #Generate an initialization vector
    bs = AES.block_size
    iv = Random.new().read(bs)

    cipher = AES.new(encryption_key, AES.MODE_CFB, iv)
    #Encrypt the data using AES 256 encryption in CBC mode using our encryption key and initialization vector.
    encrypted = cipher.encrypt(data)

    #The iv is just as important as the key for decrypting, so save it with encrypted data using a unique separator (::)
    return base64.b64encode(encrypted   '::'   iv)


def my_decrypt(data, key):
    #Remove the base64 encoding from key
    encryption_key = base64.b64decode(key)

    #To decrypt, split the encrypted data from IV - unique separator used was "::"
    encrypted_data, iv = base64.b64decode(data).split('::')

    cipher = AES.new(encryption_key, AES.MODE_CFB, iv)

    return cipher.decrypt(encrypted_data)

data = 'USER_ID||NAME||EMAIL||MOBILE'

print "Actual string: %s" %(data)
data_encrypted = my_encrypt(data, encryption_encoded_key)
print data_encrypted

data_decrypted = my_decrypt(data_encrypted, encryption_encoded_key)
print "Decrypted string: %s" %(data_decrypted)

当我尝试从python使用它时，它也可以正常工作，它能够加密/解密输入字符串，我想使用php文件加密并使用python解密输出，两者都应使用CFB模式使用AES 256加密，我在做什么错了?

This also works fine when i try to use this from python, it is able to encrypt/decrypt input string, I want to encrypt using php file and decrypt the output in python, both should use AES 256 Encryption using CFB mode, what am i doing wrong ?
