Scrypt Key Derivation

Derive scrypt keys in the browser from a password, salt, N, r, p, and output length, with HEX and Base64 output.

Scrypt Key Derivation

Scrypt Key Derivation derives keys locally in the browser from a password, salt, N, r, p, and output length, with HEX and Base64 output for backend matching, result reproduction, and security checks.

How do you use it?

  1. Enter the password.
  2. Enter the salt or upload a salt file and choose the salt format.
  3. Set N, r, p, and the output length.
  4. Generate the result and copy the HEX or Base64 derived key.

Features

  • Supports UTF-8, Hex, Base64, or file-based salt input
  • Supports tunable N, r, p parameters with memory-bound guidance
  • Outputs HEX and Base64 derived keys with copy and download support

Why use this tool?

  • Useful for checking whether your browser-side result matches backend scrypt parameters
  • Helpful for login derivation checks, security experiments, and crypto learning
  • Saves you from writing one-off scripts just to validate parameter combinations
