Python SHA512 Hash with Key

Introduction

In this tutorial, we will discuss how to implement SHA512 hashing algorithm with key in Python. SHA512 is a cryptographic hashing algorithm that generates a 512-bit hash value. The key adds an additional layer of security to the hashing process.

Prerequisites

Before we start, make sure you have the following installed:

• Python (version 3.6 or later)
• hashlib module (built-in module in Python)

Implementation

We will start by importing the hashlib module and defining a key variable.

import hashlib

# define key
key = "Python"

Next, we will create a SHA512 object using the key and message to be hashed.

# define message to be hashed
msg = "Hello, World!"

# create SHA512 object
sha512 = hashlib.sha512((msg+key).encode())

We can then get the hexadecimal representation of the hash value using the hexdigest() method.

# get hexadecimal representation of hash value
hash_val = sha512.hexdigest()

# display hash value
print("SHA512 hash value with key:", hash_val)

Conclusion

In this tutorial, we covered how to implement SHA512 hashing algorithm with key in Python. Cryptographic hashing algorithm like SHA512 is widely used for data integrity and verification. Adding a key to the hashing process can enhance security and protect against data tampering.
