To setup SSL for your account, you'll FIRST need to purchase a static IP address
Once that's setup, your account will be SSL enabled, and you'll be able to generate a secure certificate request.
After that, we suggest purchasing a Secure Certificate from RapidSSL ($14.95 USD) here: http://www.hostpc.com/rapidssl
We do not install your certificates.
Please note, HostPC is not affiliated with RapidSSL - nor do we surcharge for their certificates. We sell them because their certificates however are the best we've found for Directadmin - they just simply WORK - no fuss, no bother. We do not warranty or endorse any other certificates, they may or may not work "out of the box" with Directadmin.
