Sealva - VDS Validator

Sealva - VDS Validator is your trusted barcode scanner for verifying visible digital seals instantly and securely on your device.

Digital seals (VDS) are cryptographically signed data structures embedded in barcodes like Datamatrix. They authenticate documents and certify their integrity. Sealva makes verification effortless—simply scan any supported digital seal profile and get instant validation results. Whether you're checking official documents, certificates, or authenticity markers, the app handles the cryptographic work for you.

Your privacy and security come first. All signature verification happens locally on your device—no cloud uploads, no external servers, no sensitive data leaving your phone. The app decodes and displays seal data transparently, then validates the signature right where you scan it. This means you stay in complete control and can verify documents even without an internet connection after the initial sync.

Certificates automatically update in the background, keeping your validation rules current with the latest profiles and standards. Once synchronized, verification works offline, making the app reliable whether you're in the office or the field. You can also load your own trusted certificate sets from your organization's infrastructure for enterprise deployments.

Stored seals are always retrievable—scan once, verify anytime. Whether you need quick spot-checks or ongoing compliance verification, Sealva - VDS Validator delivers efficient, secure document authentication that works at all times, with zero compromise on security.
