I am currently a student to become a web designer. I got a new job for a company that already has a web site in place. The guy who created it is having issues over monies owed with my boss so isn't willing to go over anything with me. He'll give me the user id's and pw but only after I figure out I need it and then ask him for it. This site is pretty much all database MySQL using PHP. He sent me a couple files with the .pem extension I guess they are SSL Certs but I haven't ever done anything like this before. I have created databases and used databases (insert, update, and delete) I am using dreamweaver CS3 @ home and CS4 @ work. I am trying to figure it out researching the internet and all but I am terrified and I can't risk messing it up. Any suggestions where I should start or where I can look. :)
Welcome aboard sapphiremb99, I've been doing site programming and development for 13 years and I won't touch cert installs. This is the area of system administrators, and this is my advice to you, to get someone who knows this area to do it. It's not the work of a designer/developer. It's also a stretch for a client/employer to expect a designer to have this knowledge.
There are a few exceptions to this self-imposed rule. Some hosting plans have clear and simple tools and instructions in place to install an SSL cert and if you can access those, you might be able to get through it. But this is vendor specific, just as installing a cert is specific to the O.S.
Someone will be along shortly to offer more advice than that, but that's what I'd do.
