Scrypt Key Derivation Function

Scrypt is a password-based key derivation function (KDF) created by Colin Percival. It is designed to be memory-hard, making it resistant to hardware brute-force attacks using FPGAs and ASICs.

Unlike simpler algorithms like PBKDF2 or Bcrypt, Scrypt requires a significant amount of memory to compute, which makes parallelizing attacks on custom hardware much more expensive.

Why Use Scrypt?

Memory-Hard: Resistant to GPU and ASIC attacks.
Configurable: Adjustable CPU/memory cost (N), block size (r), and parallelization (p).
Security: High security for password storage and key derivation.
