You can get your SSL certificate signed for free from http://www.startssl.com/ whose CA is included by default in all major browsers.

You just have to be able to receive email to webmaster@yourdomain.tld for that to work.

StartSSL is a pain in the ass if you're a business, and support sucks. Great for their personal certs.

GoDaddy is the cheapest, but I hate them. Use Namecheap.

Been using Namecheap for a number of our client sites. Have been very happy. No BS, just gets the cert to me quickly.

You can't use their free certificates for commercial purposes.

I read through startssl's ToS a while back but I'm pretty sure this wasn't in there. Has their policy changed or did I miss something?

It's always been there AFAIK. This is from their current policy document which you must agree to when you start applying for a free certificate:

> Class 1 certificates are limited to client and server certificates, whereas the later is restricted in its usage for non-commercial purpose only. Subscribers MUST upgrade to Class 2 or higher level for any domain and site of commercial nature

Class 1 is "StartSSL Free", and Class 2 is "StartSSL Verified" which costs $59.90.

Geotrust (RapidSSL) isn't too expensive either.

I've used PositiveSSL certificates from Namecheap[1] successfully in the past. I think $7.95/yr is pretty cheap.

Not that off-topic since one of the owners sells certs.
