Q6: Differentiate between cryptanalysis and cryptography.

Ans Technically, any method employed to break a cipher or code is cryptanalysis. However, when We refer to cryptanalysis we are specifically talking about employing mathematical analysis to break a code. This method requires a high level of skill and sophistication. It is usually only employed by academics and governments. Today it relies very heavily on the use of ultrafast super computers.

Probably the most active and successful organization in the world, dedicated to breaking codes, is the National Security Agency (NSA). This is the largest and most secret spy agency in the United States. It is sometimes referred to as the Puzzle Palace, because the group spends so much time and energy on codes and cipher. The NSA employs tens of thousands of people. The only comparable organization in the world ever to have existed in terms of size is the former Soviet Union's KGB. But with the breakup of the Soviet Union, the NSA is now left without peers.
