Generally speaking, this is a study and practice of looking at a system of information in order to find secret codes, messages, or other information hidden within the system. There are a number of reasons why an individual or organization would have a good reason to do such a thing, both nefarious and for a greater good. It might be surprising to learn the many different uses of cryptanalysis.
When most people think of encrypted data, they think about times when they have typed in their password onto a website, and the site assures the user that their data is safe because the page has been encrypted. While this is a very powerful method of security nowadays, it should be known that there are still ways in which breaching this security system is possible. However, it would take a very good hacker to do so, and they would have to have a good reason to target your information specifically.
In many cases, cryptanalysts will look to take advantage of any weak points in an encryption, so it is important to look out for those ahead of time. What this means is having a professional take a look at a security system just to make sure it is up to par. A good rule of thumb is that if the professional sees a weakness, the hackers will see it too, and exploit it right away.
Like most advanced studies, things have been constantly changing for cryptanalysts as time has gone by. One thing that has not changed, though, is their goal of analyzing coded information. Technological advancements are the main thing that has driven this development.
The origins of this practice go all the way back to when people were doing it with a pencil and pad. Over time, things gradually became more advanced, and by World War II, immense computer systems were being used. Now, a person can have the most advanced set up on their own personal computer or laptop and do this kind of work from anywhere.
This type of specialist will start out by being given some data that has been encrypted. His or her goal is to figure out as much as they can from what they're given. Since the information they are given is coded and incomplete, this can be a very challenging task.
Breaking the code is one of the steps a cryptanalyst must take. This is basically figuring out how the message was coded. Mathematics is usually a big part of this step, since it is the only way to solve an encrypted message that is as complex as they are today.
It is after all of the equations and algorithms have been run that the codebreaker finally is able see what the hidden message is. This involves taking a look at the complete message or messages, or at least all that has been provided. This makes it clear whether the code has really been broken or if there is more work to be done.
