FAQ
What is Argon2?
Argon2 is the winner of the 2015 Password Hashing Competition (PHC), designed specifically for password storage. It resists GPU/ASIC attacks and is the most recommended password hashing algorithm today.
What's the difference between Argon2d, Argon2i, Argon2id?
Argon2d is GPU-resistant, Argon2i is side-channel-resistant, Argon2id is a hybrid of both and recommended for most use cases.
Which is better, Argon2 or Bcrypt?
Argon2 is newer and more secure with better GPU resistance and configurable memory cost. Bcrypt is mature and widely supported. New projects should prefer Argon2.
How should I set the parameters?
Recommended defaults: memory 65536KB (64MB), time 3, parallelism 4. For high-security scenarios, increase memory and time cost.
