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 (2cost 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.
