In Python we can calculate HMAC codes as follows (using the
import hashlib, hmac, binasciidef hmac_sha256(key, msg):return hmac.new(key, msg, hashlib.sha256).digest()key = b"12345"msg = b"sample message"print(binascii.hexlify(hmac_sha256(key, msg)))
Run the above code example: https://repl.it/@nakov/HMAC-SHA256-Examples.
The above code will calculate and print the expected HMAC code (like in our previous example):
Try the code yourself and play with it.
