What is Cryptography ?

Cryptography is used to secure and protect data during communication. It is helpful to prevent unauthorized person or group of users from accessing any confidential data. Encryption and decreption are the two essential functionalities of cryptography.

A message sent over the network is transformed into an unrecognizeble encrypted message known as data encryption at the receiving end, and the received message is converted to its original form known as decryption.
