Thus, the higher the number of encryption bits, the better the encryption algorithm. In other words, when you send information to the system, your browser encrypts it using a 128-bit key, then sends it to the server. The system then decodes the information and communicates with the end user via the browser using the key. The key is predetermined when your communication with the Web server is initiated. Encryption helps protect your private information so that it cannot be intercepted and read by a third party.
Encryption is the scrambling of information for transmission back and forth between two points.
A key is required to decode the information. With the release of 128-bit encryption capability and digital identity verification, you can download a Netscape or Microsoft browser that provides the highest level of encryption commercially available. Most browser versions let you easily check your level of encryption. When you visit a site that requires encryption, your browser will display a key or a padlock. If you are not in a secure area, the key or padlock will be broken.
