Problems with the OCI digital certificate

[raju_hegde]

I am trying to fill out the OCI online registration form. The webpage for it says that the digital certificate must be downloaded before filling out the application form. But then when you follow their link to the certificate page, you get to a site that is totally confusing. There are no instructions there as to what to download and how. My question is, is this 'DIGITAL CERTIFICATE' really necessary? Is this certificate required for generating a reference number and printing the hardcopy of the form? If yes, being some one who is accessing the website from US, how is the downloading done? Are there any other places for obtaining this certificate?
I will deeply apreciate any useful pointers on this.
Thanks!
