Cryptography Interview Questions and Answers

Question: What is decryption? What is its need?

Cryptography has two important modules and they are encryption and second is decryption.

Encryption is basically an approach that converts information into secret codes. It is also known as encoding. It is done to make the information secure.

On the other side decryption is a process that is opposite to it i.e. converting the coded information back to its actual form. Only the receiver knows the protocols to decode that information.
