Provide a salt.
Set N (power of 2), r, p, and key length.
Copy the derived key.

Frequently asked questions

What parameters should I use?: Common: N=16384, r=8, p=1. Increase N for more security (must be a power of 2). N=32768 or 65536 for higher security.
Why is scrypt slower than PBKDF2?: scrypt is memory-hard by design, requiring significant RAM, which makes GPU/ASIC attacks expensive.
