Argon2 Hash Generator

Encoding & Encryption · Free Online Tool

Generate Argon2id/2d/2i hashes with memory and time cost.

By CoderNewbie TeamLast updated: 2026-09-20

Browsers do not natively support Argon2 (it needs BLAKE2b + a memory-hard loop, usually delivered via WebAssembly such as hash-wasm or argon2-browser). This tool computes a PBKDF2-HMAC-SHA256 fallback using the same password/salt and a cost derived from your time-cost setting, so it is not a real Argon2 digest. Use it to explore parameters; for production Argon2, run a WASM build or a server-side library.

Input

Salt (hex)

Argon2 Type

Time cost (t): 3

Memory (KB): 65,536

Parallelism (p): 4

Key Length

Derived Key (hex)

0 chars

Configure Argon2 parameters and click "Derive Key" to compute the PBKDF2 fallback...

PHC Winner

Argon2 (argon2id recommended) is the Password Hashing Competition winner for password storage.

Memory & Time Cost

Tune t (passes), m (memory KB), and p (lanes) to set CPU and RAM hardness.

WASM Needed

Real Argon2 needs a WASM build (hash-wasm). This tool offers PBKDF2 as an in-browser fallback.

Frequently Asked Questions

Is my data safe?

Yes. All encoding, hashing, and encryption operations run entirely in your browser. Your data is never sent to any server.

Can I use this for passwords?

We recommend using the Password Generator for creating secure passwords, and Bcrypt Hash for storing password hashes. Never store plain-text passwords.
