The app for verifying invoices generated by the signed-invoice tool.
All verification steps are performed on your terminal. No data is transmitted. The application does not need internet.

This app works in two different modes:
- Reading of the invoice without authentication of the cryptographic signature (default mode): The application only reads the contents of the stamp without verifying the signature.
- Verification of the authenticity of the invoice. The application will ask you to select the document issuer's public key file. When a stamp is scanned, the signature is verified. If the signature does not match, an error is thrown and the invoice is marked as not authentic.

This app is open source and published on GitHub. Go there to contribute, donate, submit a feature request or a bug report. Any contributions are welcome!
