StartSSL is a popular certificate authority (CA). They are among the very few certificate authorities that offer SSL certificates for free. Their level one certificate is 100% free and valid for a whole year. Best thing is that it’s renewable free of charge there after.
So if you have a website that offers information for free, which means it doesn’t ask visitors to sign up and enter personal/payment information, you can use StartSSL free SSL certificate to secure connections from your server to end-user.
