What is cryptology?
Answer / pugal
A cryptosystem or cipher system is a method of disguising
messages so that only certain people can see through the
disguise. Cryptography is the art of creating and using
cryptosystems. Cryptanalysis is the art of breaking
cryptosystems---seeing through the disguise even when
you're not supposed to be able to. Cryptology is the study
of both cryptography and cryptanalysis.

what is trapdoor and how does it works?
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.
