Scrypt Hash Generator

Scrypt is a password-based key derivation function designed to be computationally intensive and memory-hard, making it resistant to hardware brute-force attacks.

Scrypt Derive / Hash
Must be a power of 2. Higher = more secure but slower. Recommended: 16384 (2^14) or higher.
Block size for mixing function. Standard value: 8. Affects memory usage.
Parallelization factor. Standard value: 1. Increase for parallel processing.

What is Scrypt?

Scrypt is a password-based key derivation function (PBKDF) created by Colin Percival in 2009. It was specifically designed to make it costly to perform large-scale custom hardware attacks by requiring large amounts of memory.

Unlike bcrypt which is CPU-intensive, scrypt is both CPU and memory-intensive, making it more resistant to attacks using specialized hardware like ASICs and GPUs. It's widely used in cryptocurrencies like Litecoin and Dogecoin.

Key Features
  • Memory-hard algorithm - requires significant RAM to compute
  • Configurable parameters (N, r, p) allow adjusting difficulty
  • Resistant to hardware brute-force attacks (GPU, ASIC)
  • Recommended for password hashing and key derivation
Security Information

Always use a random salt for each password to prevent rainbow table attacks.

Higher N values increase security but also increase computation time and memory usage.

For password hashing, recommended parameters: N=16384, r=8, p=1 (minimum for good security).
