What Is Encryption And Why Are There Different Levels? Print

Encryption is a mathematical process of coding information to make the data hidden from others. The number of bits (40-bit, 56-bit, 128-bit, 256-bit) tells you the size of the key. Like a longer password, a larger key has more possible combinations. In fact, 128-bit encryption is one trillion times strongerthan 40-bit encryption. Encryption level is determined by the capability of the web browser, SSL certificate, web server, and client computer operating system.
