What this tool does not do / Limits

This is a pasted-text analyser only. It counts integrity values but does not verify that any hash matches the file it refers to.

Frequently asked questions

Does this verify the hashes?

No. It only checks whether an integrity value is present and which algorithm it names.

Which tags are counted?

Script and link tags found in the HTML you paste.
