Server authentication SSL allows a user to confirm a server's identity. For example, you can use this ability when you are purchasing something online with a credit card but first want to verify the server's identity.
Client authentication SSL allows a server to confirm a user's identity. This functionality is often used when a server is sending sensitive informationsuch as banking information or sensitive documentsto a client system and wants to verify the client's identity.
Encrypted connections It is possible to configure SSL to require all information sent between a client and a server to be encrypted by the sending software and decrypted by the receiving software. Doing this establishes private and secure communication between two devices. In addition, SSL has a mechanism to determine whether the data sent has been tampered with or altered in transit.
You can see SSL security on the Web when you access a secure universal resource locator (URL). Secure websites begin with
https:// instead of the
http://. Hypertext Transfer Protocol over SSL (HTTPS) connections require a browser with built-in security features to establish a secure connection.
