File encoding

The threat

Encoding hides the original file bytes from simple content matching.

How the test works

Choose a dummy file and encoding. The browser encodes the file before upload; the server tries to reconstruct it.

Try it yourself

Use dummy or public test files only. Reconstructed files are auto-deleted after 10 minutes.

✓
Test pass condition

The upload is blocked, or the original file cannot be reconstructed.

✗
Test fail condition

The server reconstructs the original file.
