Aadhar eSign Flow

  1. The signer previews the document on the interface provided by ASP(Application Service Provider) and gives consent to Aadhar eSign.
  2. After giving the consent the signer is redirected to an ESP portal like NSDL/Vsign.

  4. After successful authentication, ESP orders the eSignature from the Certifying Authority. Upon receipt of the thief of the order, the Certifying Authority relays an electronic signature certificate back to the ESP.
