Hash Checker
Paste a hash to identify its algorithm (MD5 / SHA-1 / SHA-256) and see whether it matches known threat intelligence. No files are uploaded — the value you paste is sent to opentrojan.com's intelligence API for matching.
What this checks
- Detects the hash algorithm from length and character set (hex vs Base64).
- Looks up the value against our threat-indicator dataset (advisories, samples, families).
- Reports risk, a 0–100 safety score, findings with sources, and explicit caveats.
Caveats: “no known match” does not mean safe. This tool performs no content analysis, only format detection and local intelligence lookup.
