HAS-160 Digest Calculator uses HAS-160 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 HAS-160 Digest Calculator.

The operation returns a deterministic digest for the supplied input and selected settings. The digest or checksum format is specific to HAS-160 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 HAS-160 Digest Calculator.
  3. Record every size, round, variant, or seed setting beside the digest. This applies to HAS-160 Digest Calculator.
  4. Change one input byte to verify that the result changes as expected. This applies to HAS-160 Digest Calculator.

Example

Input: Short public bytes "Test message". Algorithm operation: HAS-160 Digest Calculator.

Settings: HAS-160 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 HAS-160 Digest Calculator.

Limits

  • HAS-160 Digest Calculator: A digest is one-way output and does not encrypt the input.
  • HAS-160 Digest Calculator: Digest equality depends on exact bytes, encoding, and settings.
  • HAS-160 Digest Calculator: A digest alone does not authenticate its source.

Questions

What input does HAS-160 Digest Calculator accept?

HAS-160 Digest Calculator accepts binary data or a selected file.

Which settings does HAS-160 Digest Calculator provide?

HAS-160 Digest Calculator provides controls for Rounds.

What does HAS-160 Digest Calculator return?

HAS-160 Digest Calculator returns text. HAS-160 is a cryptographic hash function designed for use with the Korean KCDSA digital signature algorithm. It is derived from SHA-1, with assorted changes intended to increase its security. It produces a 160-bit output. HAS-160 is used in the same way as SHA-1. First it divides input in blocks of 512 bits each and pads the final block. A digest function updates the intermediate hash value by processing the input blocks in turn. The message digest algorithm consists, by default, of 80 rounds.
