What is Cryptography

As the internet has become an essential tool of communication between people around the globe and is used extensively for different purposes ranging from business, shopping to financial transactions, the security of online data has become an imperative concern. There are many online security tools and applications which are extensively utilised for maintaining privacy, information and data on the internet. One such tool is cryptography which protects information and communication and secures them for those intended to receive it. Want to know more about this extensively used cybersecurity tool? This blog elaborates upon what is cryptography, listing down the best courses and universities in this field along with the career opportunities it entails. 

What is Cryptography?

Cryptography is primarily defined as the method or a process of converting a simple and ordinary text into indecipherable words. It is a method of effectively transferring data into a particular form. Data is secured in such a way that it is meant to be read by specific individuals for whom it is intended and only those people can process it further. Answering the question of “What is Cryptography” in simple terms, it fortifies and secures data from any kind of theft or maliciously intended alteration, but it can also be employed and used to authenticate a user. Besides, it performs multiple functions. It is aimed at securing data confidentiality, protecting user’s privacy, authenticating or proving the identity of a person. It also ensures the integrity of the message for both sender and the receiver. 

Now that we have understood what is cryptography is, let’s move further towards exploring the best courses offered in this field.
