PHP Hash_hmac matches python HMAC SHA1 ____php

Because of different languages, the rules for encryption are slightly different. Then this problem in the Niang can not search a correct answer, hereby record. 1. First, the two basic algorithms need to be consistent, here are the basic rules of SHA1 2.python section, if you are using digest () output, the PHP section must use raw binary data output.

Python:hmac.new (' Test ', ' test ', HASHLIB.SHA1). Digest ()
Php:hash_hmac (' SHA1 ', ' Test ', ' test ', true);

3.python Part If you are using Hexdigest () output, the PHP section removes the last raw data parameter to match.

Python:hmac.new (' Test ', ' test ', HASHLIB.SHA1). Hexdigest ()
php:hash_hmac (' SHA1 ', ' Test ', ' test ');
