I need more information on SSL certificate.
I am using AWS EC2 Ubuntu 14 with LAMP. I looked for OpenSSL as I do not have budget but it acts like first one. I need SSL which can acts like second one or third one.
More importantly, I need SSL which can work on sub-domains as well (Single Domain with Wildcard) or multiple domain on Single Server.
Can anyone suggest one which will cost less on my pocket.
