What is Encryption?
It is referred as the conversion of data into a secret code form that is safe from the unauthorized third party access, and no one can understand it. The phenomena of encryption are way too much old, and it has been used by the ancient Greeks and Romans for communicating with each other. In their times the messages were sent by substituting the common language letters with different signs and other marks, which indicates those letters. The receiver who originally meant to receive that message knew the meanings of the signs and was able to extract the original message from it. Various tools were used for making up the signs at that time. This scheme was quite useful as any other person gets the message was not able to understand it. The same phenomena leap from the pages of history and pass through a various phase of development. The modern form of such process is term as Encryption. As nowadays the communication is done through machines, the machines convert the original message into a coded form instructed by a program. This coded form is not understandable by humans and is of no use until converted back to its original form. The process of encryption has proved to be very much useful regarding data security and the user’s privacy.
What is Decryption?
Decryption is the method of converting the secretly coded data into its original form. The data in the coded form is of no use until and unless it converts into the original, meaningful form. For this purpose, the receiver of the data must be able to decrypt the data. In ancient times the messages which were sent in a secret sign based languages were only understandable by their specific and respective receivers as they were only aware of the meaning of the secret signs. They extract the original message from the signs by their converting abilities. As the machines are used for the modern communication, the machine at the destination is capable of converting the coded form of data into its original form. The machines automatically do the decryption of codes in maximum cases. However, in some situations, the phenomena are served manually as well. It is also known as un-encrypting of data.
