Use CIRCL Hash Lookup in Okou
Use CIRCL hashlookup, CIRCL hash lookup, or hashlookup.circl.lu to check MD5, SHA-1, and SHA-256 file hashes against large public reference datasets (such as the NSRL) for file identification, allow-listing, threat triage, and digital forensics. Covers single and bulk lookups, parent/child file relationships, database info and statistics, and search sessions.
Once connected, supported CIRCL Hash Lookup actions can become steps in a reusable workflow alongside the other services your team uses. Run the workflow once, on a schedule, or when an event starts it.
What you can do with CIRCL Hash Lookup
- Look up MD5, SHA-1, and SHA-256 file hashes individually or in bulk against the reference datasets.
- Read parent and child file relationships for a known SHA-1.
- Read hashlookup database information and top queried-value statistics.
- Read matching and non-matching hashes recorded in a session.
- Create a named server-side session to keep search context.
