Hash & ID Analyzer

Guess the hash type (MD5, SHA, bcrypt, NTLM and more) and decode the time inside UUIDs, ULIDs, ObjectIds and Snowflake IDs.

Free, no uploads, no sign-up. Runs 100% in your browser.

How Hash & ID Analyzer works

Hashes are matched by prefix (like $2b$ for bcrypt) and by length and alphabet, with the hashcat and John the Ripper mode for each guess. IDs are decoded by their layout: UUID versions 1, 6 and 7, ULID, MongoDB ObjectId, xid and Snowflake IDs all carry a time you can read.

Hash & ID Analyzer FAQ

Are my files uploaded?

No. This tool runs entirely in your browser tab. Files are read from your disk into memory and the result is generated locally.

Is it free? Are there limits or watermarks?

Free and open source (MIT). There are no file-size caps, daily quotas, accounts or watermarks.

Does it work offline?

Yes, once the page (and any engine it needs) has loaded, it keeps working without a connection thanks to the service worker cache.
