Python hmac (sha1) 计算

Question

我正在尝试计算 Python 中的 HMAC-SHA1 值，但结果与我用作参考的标准工具 (openSSL) 不匹配：

Python

k = "ffffffffffffffffffffffffffffffff"
m = "ffffffffffffffffffffffffffffffff"
key = k.decode("hex")
msg = m.decode("hex")
print xlong(hmac.new(key, msg=msg, digestmod=hashlib.sha1).digest())

结果：801271609151602865551107406598369208989784139177

OpenSSL

echo -n ‘ffffffffffffffffffffffffffffffff’ | xxd -r -p | openssl dgst -sha1 -mac HMAC -macopt hexkey:ffffffffffffffffffffffffffffffff

结果：8c5a42f91479bfbaed8dd538db8c4a76b44ee5a9

Answer 1

尝试在 HMAC 上使用 binascii.hexlify()：

>>> from binascii import hexlify
>>> print hexlify(hmac.new(key, msg=msg, digestmod=hashlib.sha1).digest())
8c5a42f91479bfbaed8dd538db8c4a76b44ee5a9

或者您可以只使用 str.encode('hex'):

>>> print hmac.new(key, msg=msg, digestmod=hashlib.sha1).digest().encode('hex')
8c5a42f91479bfbaed8dd538db8c4a76b44ee5a9
