Python Rijndael 加密

Question

我正在尝试模仿 http://www.hanewin.net/encrypt/aes/aes-test.htm 的 Rijndael (AES) 加密在Python3.

具体来说，当我使用以下输入时:

Key in hex = AAAABBBBCCCCDDDDEEEEFFFF00001111 
Plaintext in hex = 11112222333344445555666677778888 

我希望输出是:

Ciphertext in hex = ec151e51fc722c06073928d17fa4f6da

从网页源代码来看，它使用的是ECB。我已经安装了 PyCrypto 并按照示例进行加密，这就是我得到的:

>>> from Crypto.Cipher import AES
>>>
>>> KEY = 'AAAABBBBCCCCDDDDEEEEFFFF00001111'
>>> rijn = AES.new(KEY, AES.MODE_ECB)
>>> plaintext = '11112222333344445555666677778888'
>>> ciphertext = rijn.encrypt(plaintext)
>>> ciphertext
b'\xf8Gy\x17\x85$\xf4?\xd3}\x91\xa1\xad\xab\xa1\x07g\xf7P\xd4:\x7f\xc0\x18m)\rTu,\xd0\xa2'

所以我的密文就是那个长二进制字符串(如果这是正确的术语)。假设所有设置都正确，它应该相当于 ec151e51fc722c06073928d17fa4f6da 。我如何转换b'\xf8Gy\x17\x85$\xf4?\xd3}\x91\xa1\xad\xab\xa1\x07g\xf7P\xd4:\x7f\xc0\x18m)\rTu,\xd0\xa2'至ec151e51fc722c06073928d17fa4f6da ？

更新:根据 Jon 在评论中的建议，我导入了 binascci，现在得到以下输出:

>>> import binascii
>>> 
>>> binascii.hexlify(ciphertext)
b'f84779178524f43fd37d91a1adaba10767f750d43a7fc0186d290d54752cd0a2'

所以我的密码可能仍然是正确的，但转换过程有所不同。以下是网页源代码的一些摘录:

theForm.ciphertext.value = byteArrayToHex(rijndaelEncrypt(pt, key, "ECB"));


// This function takes an array of bytes (byteArray) and converts them
// to a hexadecimal string. Array element 0 is found at the beginning of 
// the resulting string, high nibble first. Consecutive elements follow
// similarly, for example [16, 255] --> "10ff". The function returns a 
// string.

function byteArrayToHex(byteArray) {
  var result = "";
  if (!byteArray)
    return;
  for (var i=0; i<byteArray.length; i++)
    result += ((byteArray[i]<16) ? "0" : "") + byteArray[i].toString(16);

  return result;
}

正如上面分享的，以下是评论者帮助得出的答案:

>>> from Crypto.Cipher import AES
>>> import binascii
>>> KEY = binascii.unhexlify('AAAABBBBCCCCDDDDEEEEFFFF00001111')
>>> plaintext = binascii.unhexlify('11112222333344445555666677778888')
>>> rijn = AES.new(KEY, AES.MODE_ECB)
>>> ciphertext = rijn.encrypt(plaintext)
>>> binascii.hexlify(ciphertext)
b'ec151e51fc722c06073928d17fa4f6da'
>>> print(binascii.hexlify(ciphertext).decode('utf-8'))
ec151e51fc722c06073928d17fa4f6da
