Heat [v0.4.5.2] By Edef Apr 2026

Client-side tool to generate/verify password hashes with realistic parameters. Helpful for debugging integrations and understanding how salts, memory, and iterations affect cost. Runs locally—no passwords leave your browser.

Your data security is our top priority. All hashing and verification happen in this browser. This tool does not store or send your password nor hashes outside of the browser. See source code in: https://github.com/authgear/authgear-widget-password-hash

Could you tell me more about where you encountered this or what the tool is supposed to do?

If you can provide more context—such as the it runs on (e.g., Windows, Linux, a specific game) or the field of study (e.g., thermal dynamics, networking, crypto)—I can help you look for related tools or documentation.

How to use the Password Hash Generator

Step 1.

Enter a password

Open the Generate tab and type a demo password (avoid real credentials).

Step 2.

Select an algorithm

For new systems, Argon2id is generally recommended.

Step 3.

Set parameters:

Argon2id: Memory (MiB), Iterations (t), Parallelism (p).
‍bcrypt: Cost (2^cost rounds).
scrypt: N (power of two), r, p.
PBKDF2: Iterations and digest (SHA-256/512).

Step 4.

Generate Password Hash

Click Generate Password Hash. Copy the encoded string.

Step 5.

Verify Password Hash

Switch to Verify Password Hash to test a password + encoded hash pair.

Is it safe to use this with real passwords?

All hashing happens locally in your browser. For your own safety, avoid using production secrets in any online tool.

Which hashing function should I use?

For new systems, Argon2id is generally recommended. bcrypt and scrypt are widely deployed; PBKDF2 is a compatibility fallback. Always benchmark and choose parameters that meet your latency targets.

How long should hashing take?

Many teams target ~250–500ms in the authentication path. Pick the slowest settings that still keep UX smooth on your production hardware.

Why won’t my framework verify the hash?

Common issues: whitespace/line endings, encoding mismatch (hex vs Base64), bcrypt prefix differences ( $2a$ vs $2b$ ), or forgetting a pepper.

What salt length should I use?

16–32 bytes of random data is standard. The tool defaults to secure randomness and shows length and encoding.
