How do I use hashlib in Python?

You can use the hashlib library in Python to create secure hashes. What specific hashing algorithm are you interested in?

I'm interested in SHA-256. How do I implement that?

To use SHA-256, you can do the following:

import hashlib

# Create a new sha256 hash object
hash_object = hashlib.sha256()

# Update the hash object with the bytes-like object
hash_object.update(b'Hello World')

# Get the hexadecimal representation of the hash
hex_dig = hash_object.hexdigest()
print(hex_dig)

What if I want to hash a string instead of bytes?

You can encode the string to bytes using the encode() method. For example:

hash_object.update('Hello World'.encode())
