About this tool
This page opens the password hasher with PBKDF2-SHA512 already selected — type a password, adjust the salt and iterations, and read the derived hash.
The SHA-512 variant of PBKDF2 runs on 64-bit words, which ordinary CPUs handle efficiently while commodity GPUs handle comparatively poorly — a small but real edge against brute-force rigs. Choose it over SHA-256 when your platform supports it and you want that extra margin at a similar iteration count.
The full tool also derives PBKDF2-SHA256 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.
