Generate HMAC SHA256 signature in Python
SHA256 encoded strings can be used to secure payment gateway.
For this problem, there is a popular function written in C#
which you can find here Azadehkhojandi’s Gist.
Recently, In one of the project, I was asked to convert this function into Python. After minutes of searching on google, I had no success so decided to convert it by myself and after few minutes of hit and trial, I got this -
import hmac import hashlib import binascii def create_sha256_signature(key, message): byte_key = binascii.unhexlify(key) message = message.encode() return hmac.new(byte_key, message, hashlib.sha256).hexdigest().upper() create_sha256_signature("E49756B4C8FAB4E48222A3E7F3B97CC3", "TEST STRING")
