What are some examples of hash functions in Python?

In Python, common hash functions include MD5, SHA-1, and SHA-256. Would you like to see code examples for these?

Yes, please provide an example of using SHA-256.

Sure! Here's a simple example:

import hashlib

# Create a SHA-256 hash object
hash_object = hashlib.sha256()

# Update the hash object with the bytes of the string
hash_object.update(b'Hello, World!')

# Get the hexadecimal representation of the hash
hex_dig = hash_object.hexdigest()
print(hex_dig)  # Output: 'a591a6d40bf420404a011733cfb7b190d62c65bf0bcda190f400c0b8a1e3c3e8'

What about MD5? Is it still safe to use?

MD5 is not considered secure for cryptographic purposes due to vulnerabilities. It's better to use SHA-256 or SHA-3 for security-sensitive applications.
