Hi, I would go with Rapid SSL. They are commercial but they're cheap. I think they're around $13 USD per year. You could also sign up for a really cheap web hosting account and maybe borrow their cert, depending on what host you pick. We had a situation with a small business who didn't want to pay a fortune for a cert but needed encryption for assignment forms. Rather than have a self-signed cert which would cause warnings to come up, we went with them. They worked fine and did the job. We're actually still using that cert even though the business dropped their own private server. I'm pretty sure it was $39 for three years, but that could be off. I'm also thinking that prices might have dropped, so definitely shop around first. Their site is a bit confusing and leaves a little to be desired in terms of accessibility, but it isn't too bad and probably wouldn't require importing a new root cert. http://www.rapidssl.com/ There are two of them, one is significantly more expensive and requiring a phone call or some such. You want the other one that's cheaper and just requires filling out a form and providing a valid email address. I don't remember how to get there, unfortunately. If you have questions, write off-list if you want. It's fairly simple to import into Apache, but I didn't get pop3s working.
