SSL Certificates are a great idea for any website that will deal with personal information. An SSL certificate adds trust for you visitors encrypting your site to protect their personal submitted data.
So what type of websites should look at adding this extra layer of encryption?
How do they work?
Basically, any site can claim to be a secure site. But by adding a certificate you are telling the world that a trusted third party SSL provider has issued you a certificate. Without this certificate the visitor would see a page letting them know that the website uses a self sealed certificate and it may be unsafe to visit the site.
How do you know when you are on a site that has an SSL certificate?
