What is Argon2?
Argon2 is a key derivation function that was selected as the winner of the Password Hashing Competition in 2015. It was designed to be the most secure password hashing algorithm, resistant to GPU cracking attacks, side-channel attacks, and time-memory trade-off attacks.
Argon2 Variants
Argon2id (Recommended)
Hybrid version combining Argon2i and Argon2d. Provides resistance to both side-channel and GPU attacks. Recommended for most applications.
Argon2i
Optimized to resist side-channel attacks. Uses data-independent memory access.
Argon2d
Optimized to resist GPU cracking attacks. Uses data-dependent memory access. Faster but vulnerable to side-channel attacks.
Why Choose Argon2?
- Most secure password hashing algorithm available
- Memory-hard design makes GPU attacks impractical
- Configurable memory, time, and parallelism parameters
- Resistant to side-channel attacks (Argon2i/id)
- Recommended by security experts and OWASP
