When multiple supported algorithms are present, verification uses only the strongest one, matching browser SRI selection. Any valid token using that algorithm may match.
Processing stays in your browser. Files are read into memory only for hashing (10 MiB limit); this tool never uploads or executes their contents. For cross-origin resources, browsers typically require a compatible CORS response and crossorigin="anonymous".
