What Is Scrypt?

Scrypt is a password-based key derivation function that intentionally requires significant memory, using the SMix algorithm with sequential memory-hard functions to increase the cost of GPU and ASIC attacks.

How to Generate a Scrypt derived value

  1. Choose UTF-8, Hex, Base64 input mode.
  2. Enter the text or encoded bytes you want to process.
  3. Adjust the Scrypt options if your use case requires non-default settings.
  4. Click Generate Scrypt Derived Value and copy the result.

Example Input

Sample input:

abc

Use this sample input, then copy the generated derived value from the result panel.

When Not to Use Scrypt

  • Do not use memory-hard settings in memory-constrained environments unless you have tested the target limits.
  • Do not use it when your workflow requires very fast computation.
