Argon2 Reference & Security
Argon2id (Hybrid - Recommended):Combines Argon2i and Argon2d. Provides the highest defense against both side-channel cache attacks and GPU-accelerated brute force. This is the primary standard for modern password storage.
Argon2i (Data-Independent):Accesses memory in password-independent sequences. Strong against side-channel cache timing attacks, but less resistant to GPU hardware cracking.
Argon2d (Data-Dependent):Memory access order depends on previous hash data. Maximum resistance against GPU cracking; ideal for cryptocurrencies and proof-of-work.
