SHA-256 file fingerprint generator
Drop any file to calculate its SHA-256 hash. Everything runs in your browser — your file is never uploaded.
What is a SHA-256 fingerprint?
A 64-character code computed from every byte of your file. Change one pixel or one letter and the code changes completely. Two different files practically never share the same hash.
Why a hash alone is not proof
The hash proves what the file contains, but not when it existed or who made it. For that you need an independent, signed timestamp tied to a verified identity.
Turn this into court-ready proof
A hash or a draft on your own computer has no trusted date. N1X records your file's fingerprint with a signed IST timestamp and your KYC-verified name.
