Calculate Hash

This skill calculates the cryptographic hash of any text, fully offline using the built-in WebCrypto API.

Supported Algorithms

  • SHA-256 (default — recommended)
  • SHA-512
  • SHA-384
  • SHA-1 (legacy, avoid for security-sensitive use)

Instructions

Call the run_js tool with:

  • script name: index.html
  • data: A JSON string with:
  • text: String — the text to hash
  • algorithm: String (optional) — one of SHA-256, SHA-512, SHA-384, SHA-1. Defaults to SHA-256 if not specified.

Examples

  • "What is the SHA-256 hash of 'hello world'?"
  • "Calculate the SHA-512 of this string: ..."
  • "Hash 'password123' with SHA-1"
  • "What is the hash of 'gemma'?" → use SHA-256 by default
