Password Hash Simulator

See how password hashing works — MD5, SHA-256 and SHA-512 with salt, computed locally.

Password: Salt:

Hashes appear here…

Demo only — fast hashes are NOT suitable for storing real passwords. Use bcrypt, scrypt or Argon2 in production.

How to use

Type a password and salt, then click Hash to see MD5, SHA-256 and SHA-512. Everything runs in your browser.

Is this how real apps hash passwords?

Real apps use slow hashes like bcrypt/Argon2 — this demo shows the salt+hash concept with fast hashes.

What is a salt?

Random text mixed into the password before hashing so identical passwords get different hashes.
