Which of the following statements best explains how encryption works on the Internet?

key.
B.
Encryption validates a username and password before sending information to the Web server.
C.
Encryption allows authorized users to access Web sites that offer online shopping.
D.

Explanation:
Encryption is a method of securing data while it travels over the Internet. The encryption software
encodes information from plain text to encrypted text, using specific algorithms with a string of
numbers known as a key. The encryption and decryption processes depend on both the information
sender and the receiver having knowledge of a common encryption key. The length of the
encryption key is an important security parameter. Longer key provides more secure data, as it is
more difficult to determine the encryption key.
