SSL cert renewal in Portal

Hi,

We have renew the SSL certificate in the Portal.

After logging onto the Visual admin with administrator, when I open the views from key storage.

I have create the SSL key  using the TrustedCAs and generate the CSR and send it to CA to sign.

Now my question is, is there any difference in which view I use to generate the key.

Should i have to use service_ssl in key storage?

Will that make the difference?

And store certificate is mandatory check box?

Thanks,

AP
