Does the file match?
A small integrity check. Entirely on your device.
Compare a file with an expected SHA-256 digest. Your file stays in this browser; it is not uploaded. Files are limited to 100 MiB.
What this establishes
A match establishes agreement between these file bytes and the digest you supplied. Independently establish the expected digest’s origin. This tool does not check signatures, certify truth, issue a Miskir receipt, or establish a trusted timestamp.
