Cryptograpy - Encryption and Decryption

 

Cryptography:-

        Cryptography is a process of converting plain text into unintelligible text and also do vice versa.In other word it is method of transmitting data in a particular form so that for whom it is intended can read it.

     

              There is two types of cryptography:-

1.Symmetric Key Cryptography.

2.Asymmetric Key Cryptography.

Encryption:-

        Encryption is the process of converting normal message into meaningless messages.In other words it is a conversion of something into the code so that it can't understand by others.

Decryption:-

        Decryption is the process of converting meaningless messages into normal messages which can understand by the humans.

Some functions of cryptography are:-

1.Confidentiality:-

            Information can only be accessed by the person for whom it is inteded and no other person except him can access it.

2.Integrity:-

         The information can be modified in transition between sender and recevier without any addition to information being deleted.

3.Non-repudiation:-

           The creator or sender of information or data cannot deny his or her intention to send information at the later stage.

4.Authentication:-

           The identities and destination of the sender and recever are also confrimed.

Some of the intresting and fact point about this topic are:-

1.It is a study of secure communication teniques which helps    helps in our daily life.

2.We can also do in our everyday life by secure our            email,ATMcards and many more.

3.We can text to our friends in a private way and it is not r

  eadables for other.
