Password Hash Generator

Hash passwords using SHA-256, SHA-384, SHA-512, and SHA-1 directly in your browser. See the hash output in hex or Base64 format. Your passwords never leave your device — all computation happens locally. For production password storage, use bcrypt or Argon2 with proper salting.

Frequently Asked Questions

Should I use SHA-256 for storing passwords?

For production systems, use a dedicated password hashing algorithm like bcrypt or Argon2 — they include salting and are intentionally slow to resist brute-force attacks. Plain SHA-256 is too fast for secure password storage but useful for HMAC-based auth, API key hashing, and testing.

Is my password safe when using this tool?

Yes. The hash is computed entirely in your browser using the Web Crypto API. Your password is never transmitted, logged, or stored anywhere.

What hash format should I use?

Hex is the most common format for password hashes — it's what you'll see in most documentation and databases. Base64 is more compact (fewer characters for the same data) and is common in JWT tokens and HTTP headers.
