How do I implement digest authentication in my application?

To implement digest authentication, you'll need to follow these steps: 1. Set up your server to support it. 2. Generate a nonce value. 3. Create a hash of the credentials. 4. Send the hashed credentials to the server for verification.

What is a nonce and why is it important?

A nonce is a unique, random value generated for each authentication request. It prevents replay attacks by ensuring that each request is unique.

Can you provide a code example for generating the hash?

Sure! Here's a simple example in Python:

import hashlib

def generate_digest(username, password, realm, nonce, uri, method):
    A1 = f'{username}:{realm}:{password}'
    A2 = f'{method}:{uri}'
    hashA1 = hashlib.md5(A1.encode()).hexdigest()
    hashA2 = hashlib.md5(A2.encode()).hexdigest()
    response = hashlib.md5(f'{hashA1}:{nonce}:{hashA2}').hexdigest()
    return response
