About this tool
This page opens the password hasher with Scrypt already selected — the N, r and p parameter fields replace the iteration count, so you can tune the cost right away.
Scrypt is a memory-hard KDF: N sets the CPU/memory cost, r the block size and p the parallelism. Deriving a hash forces an attacker to spend RAM as well as compute, which blunts GPU and ASIC cracking hardware — pick Scrypt when resistance to specialized rigs matters more than raw speed.
The full tool also derives PBKDF2-SHA256 and PBKDF2-SHA512 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.
