Privacy Guarantee: Calculated entirely in your local browser memory. Files are never uploaded.
Integrity Audit
Fingerprint Matching
Ensure the file you downloaded exactly matches the one provided by the author. A single bit change results in a completely different hash.
Local Processing
We use the Web Crypto API to hash files locally. Your files are never uploaded, keeping your data private and the process lightning fast.
Algorithm Note
Standard: Our tool uses the SHA-256 (Secure Hash Algorithm 2) protocol, considered the industry standard for cryptographic integrity checks.
What is the File Integrity Check?
The File Integrity Check tool looks at any file and creates a unique 'digital fingerprint' for it. If even a single letter in the file has been changed, hacked, or corrupted during download, the fingerprint will completely change. This guarantees what you downloaded is exactly what you expected.
How to use it
- Drag and drop any file into the verification box.
- Or click to browse and select a file from your computer.
- The tool will instantly calculate the file's unique fingerprint (Hash).
- Paste the original fingerprint provided by the file creator.
- If it matches, your file is safe. If it doesn't, do not open the file!
Common Use Cases
- >Checking if a software download was infected with a virus.
- >Ensuring a large video file didn't corrupt during transfer.
- >Proving that a legal document hasn't been secretly altered.
