Hash identifier and file hasher
Runs entirely in your browser. Nothing you enter is sent anywhere or stored.
How to use it
Paste a hash to see which algorithms match its length and format, or choose a file to hash.
How this works
- I can only guess a hash type from its length and format. Many algorithms share a format, so treat the result as a hint.
- File checksums use your browser's WebCrypto API (SHA-256, SHA-384, SHA-512). Your browser reads the file locally. It is never uploaded and I never see it.
- Compare the checksum with the one the publisher lists to confirm your download was not altered.
