Calculate or verify a digest with Ascon Hash. Enter the data, choose the digest options, then copy the calculated value.

This tool runs open-source code from CyberChef by GCHQ (Apache License 2.0). See open-source credits.

Ascon Hash Calculator uses Ascon Hash Calculator for the supplied input. It returns the hash bytes as hexadecimal, not an authenticated ciphertext or a password verification record.

It returns the hash bytes as hexadecimal, not an authenticated ciphertext or a password verification record. This result runs in the browser for this catalog category. Processing runs in the browser.

This operation reports a digest or checksum; it does not provide encryption, identity, or complete application security.

Instructions

  1. Provide text or data for this tool.
  2. Use the same byte encoding in the system that receives the digest. This applies to Ascon Hash Calculator.
  3. Compare with a test vector for the installed Ascon implementation before protocol integration. This applies to Ascon Hash Calculator.

Example

Input: Supply ASCII "abc" as three bytes, without a trailing newline.

Settings: Ascon Hash Calculator: This operation exposes no key, salt, or digest-length control. The implementation passes bytes to JsAscon.hash.

Result: It returns the hash bytes as hexadecimal, not an authenticated ciphertext or a password verification record.

Limits

  • Ascon Hash Calculator: A hash call does not perform Ascon authenticated encryption.
  • Ascon Hash Calculator: Check variant compatibility with your reference implementation; the name alone does not establish interoperability.

Questions

What input does Ascon Hash Calculator accept?

Ascon Hash Calculator accepts binary data or a selected file.

Does Ascon Hash Calculator need extra settings?

Ascon Hash Calculator does not define extra operation settings. It uses its built-in behavior with the supplied input.

What does Ascon Hash Calculator return?

Ascon Hash Calculator returns text. Ascon-Hash256 produces a fixed 256-bit (32-byte) cryptographic hash as standardised in NIST SP 800-232. Ascon is a family of lightweight authenticated encryption and hashing algorithms designed for constrained devices such as IoT sensors and embedded systems. The algorithm was selected by NIST in 2023 as the new standard for lightweight cryptography after a multi-year competition.
