当AES256加密字符串时，为什么我从python和php得到不同的结果？

Question

其思想是AES加密一个字符串并将其发送到我的服务器端，然后在那里解密以获得真正的字符串。但是它不起作用，奇怪的是，我发现即使在python和php上分别使用AES-256加密字符串，结果也不一样。在

Python示例：

from Crypto.Cipher import AES
import base64

original = "originalstring"
key = "12345678123456781234567812345678"
IV = "1234567812345678"

b64encodedOnly = base64.b64encode(original)

encryptCipher = AES.new(key, AES.MODE_CFB, IV)
encrypted = base64.b64encode(encryptCipher.encrypt(original))

decryptCipher = AES.new(key, AES.MODE_CFB, IV)
decrypted = decryptCipher.decrypt(base64.b64decode(encrypted))

print "original:", original
print "b64encoded only:", b64encodedOnly
print "AES-256 encrypted:", encrypted
print "AES-256 decrypted:", decrypted

Python输出：

^{pr2}$

PHP示例：

<?php
$original = "originalstring";
$key = "12345678123456781234567812345678";
$IV = "1234567812345678";

$b64encodedOnly = base64_encode($original);
$encrypted = base64_encode(mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $original, MCRYPT_MODE_CFB, $IV));
$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, base64_decode($encrypted), MCRYPT_MODE_CFB, $IV);

echo "original: " . $original . "<br />";
echo "b64encoded only: " . $b64encodedOnly . "<br />";
echo "AES-256 encrypted: " . $encrypted . "<br />";
echo "AES-256 decrypted: " . $decrypted . "<br />";

?>

PHP输出：

original: originalstring
b64encoded only: b3JpZ2luYWxzdHJpbmc=
AES-256 encrypted: +w9F6zLD2avTt9fj8aM=
AES-256 decrypted: originalstring

正如在AES-256（CFB模式）加密之后，然后是base64编码，"originalstring"在python上变成{}，而在PHP上是{}。显然base64的功能是一样的，因为对原始字符串的编码结果是一样的，所以唯一的问题似乎是在AES加密方面，我相信这是在不同平台上实现的同一个算法，结果怎么会不一样呢？在

我发现了一个问题：MCRYPT_RIJNDAEL_256并不等同于AES_256。
