## What is Sealva?

Simply scan and verify visible digital seals!

VDS are visual cryptographically signed data structures encoded in barcodes such as Datamatrix. Sealva supports a wide range of current digital seal profiles and is prepared for future new profiles. Digital signatures are always verified locally—no cloud, no storage of sensitive data outside the device. The data contained is clearly displayed and the signature is checked locally – securely and directly on the device. Stored seals can be retrieved and checked again at any time. 

The certificates required for verification are automatically updated in the background. After synchronization, verification is possible even without an Internet connection. It is possible to either receive the centrally provided certificates or load your own  trusted certificate sets that can be obtained from your own infrastructure.

A reliable solution for digital document verification based on visible digital seals – efficient, secure, and available at all times.
