SSL is the industry standard security protocol to encode sensitive information, such as your credit card number. SSL creates a shared digital key, which only lets the sender and the receiver of the transmission scramble or unscramble information. To everyone else, even the servers relaying the message, the SSL transmission is indecipherable. SSL encryption can only be broken by intercepting the encrypted message, recording it, and using a computer to try every possible combination until the key is cracked. Most keys range from 40 to 1,024 digits long...as you can imagine, the number of possible combinations can be into the billions and beyond!
