AES 128 in Python
提问by TomasG
I don't know why when I encrypt in AES a text with the PyCrypto (Crypto.Cipher- AES), the result isn't the same as the ciphertext generate by a code in C.
我不知道为什么当我在 AES 中使用 PyCrypto (Crypto.Cipher-AES) 加密文本时，结果与 C 中的代码生成的密文不同。
For example, the following code gives me
例如，下面的代码给了我

instead of

here is my code:
这是我的代码：
key = '1F61ECB5ED5D6BAF8D7A7068B28DCC8E'
IV = 16 * '\x00'
mode = AES.MODE_CBC
encryptor = AES.new(key, mode, IV=IV)
text = '020ABC00ABCDEFf8d500000123456789'
ciphertext = encryptor.encrypt(text)
print binascii.hexlify(ciphertext)
采纳答案by Roland Smith
You need to unhexlifyboth the key and text (example in IPython using Python 3);
您需要unhexlify密钥和文本（在使用 Python 3 的 IPython 中的示例）；
In [1]: from Crypto.Cipher import AES
In [2]: import binascii
In [3]: import os
In [4]: key = binascii.unhexlify('1F61ECB5ED5D6BAF8D7A7068B28DCC8E')
In [5]: IV = os.urandom(16)
In [6]: binascii.hexlify(IV).upper()
Out[6]: b'3C118E12E1677B8F21D4922BE4B2398E'
In [7]: encryptor = AES.new(key, AES.MODE_CBC, IV=IV)
In [8]: text = binascii.unhexlify('020ABC00ABCDEFf8d500000123456789')
In [9]: ciphertext = encryptor.encrypt(text)
In [10]: print(binascii.hexlify(ciphertext).upper())

Edit:As André Caron correctly states in the comments, it is generally a bad ideato use an IV consisting of only zeroes. I've changed the code to use a random IV. Note that the IV should also be communicated to the receiver; it is needed for decryption. Often the IV is prepended to the ciphertext.
编辑：正如 André Caron 在评论中正确指出的那样，使用仅由零组成的 IV通常是一个坏主意。我已将代码更改为使用随机 IV。请注意，IV 也应传达给接收者；解密需要它。通常在密文前面加上 IV。
