Compute SHA-256 / SHA-1 of a file locally, then open VirusTotal’s report for that hash. The file itself is never uploaded to DevToolBox.
VirusTotal lookup uses only the hash via their public GUI URL. If the file was never seen by VT, the report page may show “no matches” until someone uploads it there (we never upload for you).
Malware scanners often identify known samples by cryptographic hash (SHA-256). If you only need to know whether a file hash is already flagged, you can hash locally and query VirusTotal by hash—without uploading the binary to our servers.
Privacy model: hashing uses the Web Crypto API in your browser. Clicking “Open on VirusTotal” sends only the hash in the URL to VirusTotal (their service and policy apply). We do not receive the file.
No API key and no server proxy. We open VT’s public file report URL for the hash.
No. Use endpoint protection and careful handling of untrusted files.
