I believe that the examples in the book would be harder to decipher when no assistance is given. It would be hard to decipher the message while not knowing what type of cipher it is. Telling the readers what kind of code the message is encrypted as gives a hint in how to solve it. If there was no hint, the receiver of the message would have to just guess on how to decipher the message. There are ways to get clues on what type of code is used such as frequency analysis; however, frequency analysis may not be very helpful depending on what type of code was used.
It is easy to understand Singh’s examples in the book because he is trying to teach the readers how to decode the message. The examples that Singh gives are also easy to crack since no one is trying to keep the message hidden anymore. It is easier to decode the messages now than it would be during the time of war. I think that it is harder to decipher codes when in certain situations. The idea that the contents of a message can help alleviate impending war can put an enormous amount of pressure on a person’s shoulder. When I am in stressful situations, an exam, for example, I often make silly mistakes because of how nervous I am. That feeling is a thousand times worse during the times of war because it is not a grade that is at stake, it is the livelihood of a country.
