Tutorials on how to use Kerika.

Wrestling with SSL certificates

We had previously been using SSL certificates for our website (kerika.com) and this blog (which is on a subdomain: blog.kerika.com) that we got from GoDaddy, but we have moved away from them.

What pushed us away was their aggressive approach to billing customers: they automatically renewed our SSL certificates after just 9 months into a 12-month contract, which we found unacceptable.  Talking to their customer service people was an unhappy experience as well, so we decided to not do any more business with GoDaddy.

Now we are using a SSL from Amazon for our website and app (kerika.com): Amazon actually provides free SSL certificates to sites hosted on Amazon Web Services, and it was easy and simple to set up.

However, AWS doesn’t provide wildcard SSL certificates so we couldn’t handle our blog as well — particularly as our blog isn’t hosted at AWS. Instead we got a SSL certificate for the blog from RapidSSL which is reasonably priced.

So far, so good.
