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

BLAKE3 Digest Calculator uses BLAKE3 for the supplied input. The operation returns a deterministic digest for the supplied input and selected settings. The digest or checksum format is specific to BLAKE3 Digest Calculator.

The operation returns a deterministic digest for the supplied input and selected settings. The digest or checksum format is specific to BLAKE3 Digest Calculator. This result runs in the browser for this catalog category. Processing runs in the browser.

This digest provides deterministic comparison output; it does not provide encryption or source authentication.

Instructions

  1. Provide text or data for this tool.
  2. Use a short public fixture. This applies to BLAKE3 Digest Calculator.
  3. Record every size, round, variant, or seed setting beside the digest. This applies to BLAKE3 Digest Calculator.
  4. Change one input byte to verify that the result changes as expected. This applies to BLAKE3 Digest Calculator.

Example

Input: Short public bytes "Test message". Algorithm operation: BLAKE3 Digest Calculator.

Settings: BLAKE3 Digest Calculator: Use the operation's documented input encoding. Select digest size, rounds, variant, seed, or output encoding when shown. Keep byte order and formatting unchanged when comparing outputs.

Result: The operation returns a deterministic digest for the supplied input and selected settings. The digest or checksum format is specific to BLAKE3 Digest Calculator.

Limits

  • BLAKE3 Digest Calculator: A digest is one-way output and does not encrypt the input.
  • BLAKE3 Digest Calculator: Digest equality depends on exact bytes, encoding, and settings.
  • BLAKE3 Digest Calculator: A digest alone does not authenticate its source.
