Anyone who wishes to sign messages or to receive encrypted
messages must have a key pair. People may have more than
one key pair. In fact, it is advisable to use separate key
pairs for signing messages and receiving encrypted
messages. As another example, someone might have a key pair
affiliated with his or her work and a separate key pair for
personal use. Other entities may also have key pairs,
including electronic entities such as modems, workstations,
web servers (web sites) and printers, as well as
organizational entities such as a corporate department, a
hotel registration desk, or a university registrar's
office. Key pairs allow people and other entities to
authenticate (see Question 2.2.2) and encrypt messages.
Corporations may require more than one key pair for
communication. They may use one or more key pairs for
encryption (with the keys stored under key escrow to
safeguard the key in event of loss) and use a single non-
escrowed key pair for authentication. The lengths of the
encryption and authentication key pairs may be varied
according to the desired security.

A company wants to transmit data over the telephone, but it is concerned that its phones may be tapped. All of its data is transmitted as four-digit integers. It has asked you to write a program that will encrypt its data so that the data may be transmitted more securely. Your script should read a four digit integer entered by the user in a prompt dialog and encrypt it as follows: Replace each digit by (the sum of that digit plus 7) modulus 10. Then swap the first digit with the third, and swap the second digit with the fourth. Then output XHTML text that displays the encrypted integer.
