Baappay | Cryptography - Types and Advantages of Cryptography

Baappay | The simplest definition available as to, what cryptography is is that it is the science of using mathematics to encrypt and decrypt information, which means putting into or decoding 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.

Cryptography 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 by 0.3. 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 of 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.

Why do you need cryptosystems, Government, private companies and universities exchange data over Internet with their trusted partners? They want full secure data exchange; no hacker or third party should be able to intercept the important data. To over come privacy, secrecy and importance of data being hacked or stolen, cryptography provides two kinds of cryptosystems.

First is "Symmetric" system under, which cryptosystems use the same secret key to encrypt or decrypt a message received data packet from trusted partners.

Baappay | The other cryptosystem is asymmetric system under, which two different keys are used to encrypt and decrypt the message or received data packet. On public key is used to encrypt the data or message and the private key on receiving end is used to decrypt the message or data packet.
