The Power of SSL
Once the handshake is completed, your browser will automatically encrypt all information that you send to the site, before it leaves your computer. Encrypted information is unreadable en route. Once the information arrives at the secure server, it is decrypted using a secret key. If the server sends information back to you, that information is also encrypted at the server’s end before being sent. Your browser will decrypt it for you automatically upon arrival, then display it as it normally does.
For those running a secure server it is also possible to authenticate the client connecting to the server to ensure, for example, that the person is not pretending to be someone who has been granted restricted access. Another feature of SSL technology is the ability to authenticate data so that an interceder cannot substitute another transmission for the actual transmission without being detected.
Though SSL makes exchanging sensitive information online secure, it cannot guarantee that the information will continue to be kept secure once it arrives safely at the server. For assurance that sensitive information is handled properly once it has been received, you must read the site’s privacy policy. It does little good to trust your personal data to SSL, if the people who ultimately have it will be sharing it with third parties, or keeping it on servers that are not bound by restricted access and other security protocols. Therefore it is always wise to read any site’s privacy policy, which includes security measures, before volunteering your personal information online.
