Introduction

The hashfish python module allows you to easily use salted HMACs for data hashing. It acts as a simple "wrapper" for some of the functions in the hmac module from the standard library. Hashfish allows you to hash data and check the hashes using a quick and easy implementation; one function is for hashing, one for generating secure salt, and one function is for checking (+ one for testing).

Usage

The usage for hashfish is simple; an example script is shown below:

import hashfish

msg = 'Hello, world!' # Message
key = 'Some key...' # Key/Password
slt = hashfish.new_salt() # Length of choice may be used by changing the length keyword argument. Default is 16 characters long.
dmd = 'sha256' # Algorithm to use. See hmac.new(...).
mac = hashfish.new_salty_hmac(msg, key, slt, dmd) # Actually create the HMAC.
print(verify_salty_hmac(mac, msg, key, dmd)) # Test if verified. Should return [bool] True.

Testing

In order to test the module, either run as main or call hashfish.test().
The test code is pretty much the same as the example code.
