In simple terms, an SSL certificate is a communications protocol that provides security for web developers and users whilst using the Internet. This type of safeguard is important since the information sent across the Internet is essentially unsecured and, in theory, could be intercepted and accessed by a third party.
SSL certificates provide a layer of confidentiality and security
that ensures privacy for users when transferring sensitive information between websites or through email. For this reason an SSL, or Secure Socket Layer, is integral to the successful operation of web based business and other concerns that deal with users' personal information.
An SSL certificate is associated with your particular domain name and so, when you buy an SSL certificate from 1&1, you are ensuring that any data sent between your server
and the client is secured against external threats. The user's browser decodes the data and displays the familiar lock icon
for verification, in addition to this, rather than the usual "http" prefix, users will see "https
" within the address bar.
Since there are various types of SSL certificates, each website should select the most suitable certificate for the given application.
