File encrypting

The threat

Encrypted uploads hide file contents from controls that depend on reading the body.

How the test works

Choose a dummy file and encryption mode. The browser encrypts it and sends the metadata needed for reconstruction.

Try it yourself

Password: 123456. Use dummy files only. Reconstructed files are auto-deleted after 10 minutes.

✓
Test pass condition

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

✗
Test fail condition

The server decrypts and reconstructs the original file.
