How do I implement Argon2 for password hashing?

To implement Argon2, you can use libraries available in various programming languages. Which language are you using?

I'm using Python. Can you provide a code example?

Sure! You can use the argon2-cffi library. Here's a simple example:

from argon2 import PasswordHasher

ph = PasswordHasher()

# Hash a password
hash = ph.hash("my_password")

# Verify a password
try:
    ph.verify(hash, "my_password")
    print("Password is valid!")
except Exception:
    print("Invalid password!")

What are the benefits of using Argon2 over other hashing algorithms?

Argon2 is designed to be memory-hard, making it resistant to GPU-based attacks. It also allows you to configure time and memory costs, enhancing security.
