`It is an indispensable tool for protecting information in computer systems. This helps to emphasize the inner workings of the cryptographic primitives and how to correctly use them. People will learn how to reason about the security of cryptographic constructions, and how to apply this knowledge to real world applications. It is concerned with the construction of schemes that withstand any abuse. Such schemes are constructed so to maintain a desired functionality, even under malicious attempts aimed at working them deviate from their prescribed functionality. A science which helps in transforming messages to make them secure and immune to attack. The literal meaning of cryptography is “ secret writing”. If the original message is sent through a network, then the hacker can get access and change its meaning. To ensure the security of the message, the original message is transformed to cipher-text using an encryption algorithm by the sender. And the receiver uses decryption algorithm to transform the cipertext back into plain text. The simplest definition available as to, what cryptography is that is the science of using mathematics to encrypt and decrypt information, which means putting into or decorating from a mathematical language. What are the ways to use this technology and learn what are advantages? So, as you can see, this seems as though cryptography would be very difficult. Nevertheless, this is important because everything on your computer is stored in cryptography. These becomes even more complex though. This is because humans recognize numbers as digits from 0 to 9, but your computer can only recognize 0 and 1. As such, this binary system uses bits instead of digits. In order to convert bits to digits you will need to multiply the number of bits by0.3. This will then provide you with a good estimation of what it stands for. Now there are some other definitions that are important to understand here. First, you should understand that a brute force attack is when all of the possible combinations of numbers are used to either decrypt or encrypt materials. Secondly, a dictionary attack occurs whenever a person tries using all possible known passwords, which is surprisingly a small amount, to form an attack. Of course, there are some people, such as the government who would profit from knowing cryptography and are thus known as an adversary. On the other hand, those who should not profit from this access are known as a key logger. All of this probably still sounds very difficult to understand. This is why it takes so much education if you want to work as a cryptographer. There are only some people who can truly understand all of this and thus use it to help all the rest of us with our daily computer needs. Of course, it is also why the people who work in this field make such good money doing so.`
