Argon2i FAQ
What is Argon2i?
Argon2i is a variant of Argon2 optimized for resistance against side-channel attacks. It uses data-independent memory access patterns, making it suitable for environments where side-channel attacks are a concern.
Argon2i vs Argon2id?
Argon2id (hybrid) is generally recommended for password hashing as it combines Argon2i's side-channel resistance with Argon2d's GPU resistance. Argon2i is preferred only in specific side-channel threat models.
What parameters should I use?
OWASP recommends: memory ≥ 19 MiB (19456 KB), iterations ≥ 2, parallelism = 1. Increase memory first, then iterations. Target ~1 second per hash.
Why is Argon2 better than bcrypt?
Argon2 is memory-hard, making GPU/ASIC attacks much more expensive. bcrypt uses only 4 KB of memory, while Argon2 can require megabytes, dramatically increasing attack costs.
