Python replacement for PHP's hash_hmac [ edit | history ]

import hmac
h = hmac.new(key, data, digest_module)
# hex output:
result = h.hexdigest()
# raw output:
result = h.digest()

Here's an example using sha256, first in php, then python:

echo hash_hmac("sha256","a", "1");

Python version:

import hmac,hashlib
key='1'
data='a'
print hmac.new(key, data, hashlib.sha256).hexdigest()

Result in both cases is c6e693d0b35805080632bc2469e1154a8d1072a86557778c27a01329630f8917
or

import hashlib
import hmac

def hash_hmac(algo, data, key):
    res = hmac.new(key.encode(), data.encode(), algo).hexdigest()
    return res

print(hash_hmac('ripemd160', 'The quick brown fox jumped over the lazy dog.', 'secret'))

returns b8e7ae12510bdfb1812e463a7f086122cf37e4f7

(PHP 5 >= 5.1.2, PECL hash >= 1.1)

hash_hmac — Generate a keyed hash value using the HMAC method

Description

string hash_hmac ( string $algo , string $data , string $key [, bool $raw_output= false ] )

Parameters

algo: Name of selected hashing algorithm (i.e. "md5", "sha256", "haval160,4", etc..)
data: Message to be hashed.
key: Shared secret key used for generating the HMAC variant of the message digest.
raw_output: When set to TRUE, outputs raw binary data. Default value (FALSE) outputs lowercase hexits.

Return Values

Returns a string containing the calculated message digest as lowercase hexits unless raw_output is set to true in which case the raw binary representation of the message digest is returned.

Examples

Example #1 hash_hmac() example


<?php
