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.
