For websites that deal with personal data, or transactions via the Internet, it is necessary to take measures for security of the web application. Processing transactions should be handled securely on the web. Meaning that we need to be able to transmit information between the web site and the web browser in a way that makes it difficult for other the server to intercept and read. To deal with such situations where we need security, we need a SSL or Secure Sockets Layer to take care of this.
What is SSL (Secure Sockets Layer) ? SSL is a a protocol much like the standard HTTP, but is a secure protocol that can receive and transfer data over the Internet. An encrypted SSL connection requires that the encrypted data to be passed to and from the web server and the web browser and to be decrypted at the receiving end. A SSL certificate is used to authenticate a web site.
What are SSL certificates ? The certificate contains the server’s public key, which is used by the browser to identify and authenticate the server and encrypt the information from the server using SSL. SSL certificates are much like any identification proof that once authenticated, permits the flow of encrypted information through the HTTPS.
There are three different types of SSL certificates you could use. Generally your web hosting companies may provide SSL certification for your website. Some may provide it as a free service, although it may not be any more secure than the standard HTTP.
Shared SSL : As the name suggests, multiple domain names share the same IP address making it easier for the host to managed single shared SSL over different servers. This is a comparatively cheaper method, as single SSL needed to encrypt an array of web sites.
Dedicated SSL : Dedicated SSL, much like dedicated hosting has SSL certification specifically for your root domain space. An HTTPS connection is verfied through a designated IP address. It is the most secure method but comes at a price.
Wildcard SSL : Wildcard SSL certifications will have multiple sub-domains for your website.
