Digital degrees and digital mark sheets are digitally born for graduating students. Under this approach, the degree certificates and mark sheets are given in a digital Portable Document Format (PDF). All such PDF documents are digitally signed by appropriate authorities using Cryptographic Message Syntax (CMS) standards and are enabled for Long-Term Validation (LTV). Therefore, the documents will be verifiable anytime even after several years. Digital documents are also provided on DigiLocker, a Govt. of India initiative which serves as a secure document gateway acting as a secure document exchange platform between trusted issuer and trusted Requester/Verifier, thus providing authenticity to the document. To verify the documents, one would need a standard PDF viewer that supports the digital signature verifications. The signatures in the pdf file may be verified using the signature panel in Adobe PDF Reader (or equivalently some other button in other viewers).
