What is Data Encryption and Why do you need it? – Data Encryption Meaning

The answer to the 1st part of the question in the simplest words would be to access the information which is in the form of data only by correct encryption.


The definition of encryption is the process of encoding or accessing any information in a predefined security procedure to make the data available to only authorized users.


To understand it even better let us take an example. Suppose that a person is browsing the internet and does purchase using an online store. There he chooses credit card as the payment mode. Now when he is logged in to the account, the data is uploaded through his computer to the server. The data is exchanged between the server and the user’s computer.


If this data is not encrypted then any third party or hacker can easily access the credit card details. But if data encryption is enabled then a security system would scramble the original data and it would not be accessible to the hacker in the simpler form rather he would not be able to understand it.


SSL certificate is the term that we hear a lot of times. It means secure socket layer, a public key which was developed by Netscape. The secure socket layer uses RSA public key for authentication. Well encryption also protects the data which is sent from various devices rather than only the internet.
