How to Validate Digital Signatures on e-Aadhaar?

After downloading your E-aadhaar letter online you may have noticed that, in place of digital signatures it shows Validity Unknown. It is because that you haven't added the signatory to your trusted certificates. If you see the Validity Unknown icon on your e-Aadhaar, please follow the below steps to Validate it.
