About Scrypt
Scrypt is a password derivation function designed by Colin Percival in 2009, specifically designed as a memory-hard algorithm that requires significant memory to compute, effectively resisting ASIC and GPU parallel attacks.
Important: Never store plaintext passwords! Always use password hashing algorithms like Scrypt to store user passwords. These algorithms have built-in salt generation, which effectively prevents rainbow table attacks.
Scrypt Features
Scrypt is widely used in cryptocurrencies (such as Litecoin) and password storage. Its parameters N, r, and p can adjust CPU and memory costs. N is the CPU/memory cost factor (recommended 16384), r is the block size (usually 8), and p is the parallelism (usually 1).
Best Practices
- Use N≥16384, adjust parameters based on hardware performance
- Never store plaintext passwords or use MD5/SHA for password hashing
- Regularly update parameters to keep up with hardware development
