About this tool
This page opens the password hasher with PBKDF2-SHA256 already selected — type a password, adjust the salt and iteration count, and read the derived hash.
PBKDF2 with HMAC-SHA256 stretches a password by repeating the hash for thousands of iterations; the iteration count is your work-factor dial. It is a long-standing standards-track KDF with native Web Crypto support, so it is often the pragmatic pick for interoperable password storage — raise the iterations until derivation takes a noticeable fraction of a second.
The full tool also derives PBKDF2-SHA512 and memory-hard Scrypt hashes and shows a live timing estimate. Everything is computed locally in your browser — the password never leaves your machine.
Example. PBKDF2 with SHA-256, a password, a salt, and 100000 iterations returns a 256-bit key printed as hexadecimal.
Limit. The PBKDF2 output length is fixed at 256 bits, and scrypt memory cost follows the selected N, r, and p rather than an arbitrary Argon2 profile.
