Cryptography Interview Questions and Answers

Question: What do you mean by Secret Key Cryptography and Public Key Cryptography? How they are different from one another

Both these are the algorithms of encryption and contribute to data security.

Secret Key Cryptography can be used for both encryptions as well as decryption. It is also considered an asymmetric approach and contains only one key.

On the other hand, Public Key cryptography is basically an asymmetric approach.

There are two keys in this approach and one is basically the public key and any user can access the information. The other key is private and can only be accessed by the administrator.
