File Integrity Verification
Generate and compare file hashes to verify downloads and detect tampering.
Verify file integrity
Compute a cryptographic fingerprint of your file. Share the hash alongside the file so others can verify their copy is byte-for-byte identical to yours. Nothing leaves your device.
Algorithms
Compare a hash
Paste a known hash (from a download page, vendor site, or previous scan) and upload the file to check if they match. The algorithm is detected automatically from the hash length.
Compare two files
Upload two files to check whether they are byte-for-byte identical. If their sizes differ, the check short-circuits immediately — no hashing needed. Nothing leaves your device.
