What is Cryptography?

Cryptography is mainly defined as the method or process of converting a simple and ordinary text into indecipherable words. It is a method of effectively transferring data in a particular form. The data is secured in such a way that it is meant to be read by the specific persons for whom it is intended and only those persons can further process it. 

Answering the question of “Cryptography Kya Hai” in Simple Words, it strengthens and secures the data from any kind of theft or maliciously intended alteration, but it is also used to authenticate the user. can go. In addition, it performs many functions. Its purpose is to achieve data confidentiality, protect user privacy, authenticate or prove the identity of an individual. It also ensures the integrity of the message for both the sender and the receiver.

Cryptography Techniques

Cryptography Techniques

There are four techniques in modern cryptography that you must know about. Know about these techniques in Cryptography Kya Hai.

  • Confidentiality: Information not to be understood by those who are not intended
  • Integrity: Information should not be converted in storage or in transit between sender and receiver without any change being detected
  • Non-repudiation: The creator cannot deny at a later stage of his intention to create or broadcast the information
  • Authentication: Sender and receiver can verify each other’s identity and origin and destination of information

Now that we understand what cryptography is, let us move towards discovering the best courses that this field has to offer. The aim of these courses is to provide the students with the knowledge of applications in programming and coding languages, information security as well as cybersecurity. Have a look at the following sections which explains the Top Cryptography Courses at different levels.
