What Is KeccakPRG?

KeccakPRG is a pseudo-random generator based on Keccak, using a sponge construction with configurable capacity to generate random output from seed entropy with support for reseeding and forward secrecy.

How to Generate a KeccakPRG hash

  1. Choose UTF-8, Hex, Base64, or File input mode.
  2. Enter text, encoded bytes, or choose a local file to process.
  3. Adjust the KeccakPRG options if your use case requires non-default settings.
  4. Click Generate KeccakPRG Hash and copy the result.

Example Input

Sample input:

abc

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

When Not to Use KeccakPRG

  • Do not use a plain hash or derivation output directly as password storage without the right password-hashing construction and parameters.
  • Do not use it when you need a conventional deterministic hash digest.

Recommended Alternatives
