I have a SSL certificate that I purchased from an authorized agency. I had it in a simple text format being copied in an email from the agency.
Now I need to upload this to a Barracuda appliance.
I simply tried copying it onto a txt file, and saved it with .cer extension. Its icon now looks like a certificate but when I as a test try to double click on it, I get "this is not a valid certificate" message. And of course when I tried to upload that looking-like-certificate file onto the appliance, I get an error.
My question is whether there is any right way of converting it into a valid one?
