About Argon2
Argon2 is the winner of the 2015 Password Hashing Competition and is considered the most secure password hashing algorithm currently available. It has three variants: Argon2d (resistant to GPU attacks), Argon2i (resistant to side-channel attacks), and Argon2id (combining both, recommended for password hashing).
Important: Never store plaintext passwords! Always use password hashing algorithms like Argon2 to store user passwords. These algorithms have built-in salt generation, which effectively prevents rainbow table attacks.
Argon2 Features
Argon2 can configure memory, iteration count, and parallelism parameters. Argon2id is recommended, with memory ≥64MB, iterations ≥3, and parallelism adjusted based on CPU cores. Argon2 provides the highest security and is the best choice for password storage.
Best Practices
- Use Argon2id as the first choice, with memory ≥64MB
- Never store plaintext passwords or use MD5/SHA for password hashing
- Regularly update parameters to keep up with hardware development
