>SSL Certificate and dedicated IP address
If your website deals with sensitive information, especially financial transactions, you need to provide secure communication.
This is achieved with an SSL (Secure Sockets Layer) certificate issued by a trusted authority. You need subscribe to a certificate provider and then have the certificate installed on your web server.
After an SSL certificate is installed a fully encrypted session is established by using the following prefix to the web address.
http:// (non encrypted)
You will often also see a padlock or some other symbol in your browser indicating that you have a secure connection.
The cost of an SSL certificate ranges from just over $20 to hundreds of dollars depending on the issuing authority.
Your domain name register will usually also offer SSL certificates but you can shop around for the best offer.
The SSL certificate required a dedicated IP address and will usually charge an additional monthly fee for this which should not be more that $2 per month. A good host will also assist you in installing your certificate. Dedicated IP addresses will not be an option on most cheap hosting packages.
