Cryptography Pertanyaan dan Jawaban Wawancara

Ques 6. How Hash Functions are different from Public Key Cryptography and Secret Key Cryptography?

They are basically considered single-way encryption.

Unlike Public Key Cryptography and Secret Key Cryptography, they don’t have any key in them and their prime function is to make sure that a file has reached its destination without any modification. 

Ques 7. What type of information can be secured with Cryptography?

Well, there is no strict upper limit on that. Any information that needs some privacy can be encrypted with this approach.

However, in the present scenario, most of the information belongs to secret operations, business data, defense applications, and lots more.

Cryptography is an approach that can encode both digital, as well as analog information and data without facing any issue.

Ques 8. In case a Cryptography tool is not available and you need to send secret information, would you proceed or wait till the presence of the tool?

It all depends on the security of the network itself in such a case. If the network is secure, the information can be shared.

In case not, I will probably wait for the Cryptography tool to be active. This is because any information without proper encryption can easily be leaked. 

Ques 9. What exactly do you know about RSA?

It is basically a public key cryptography approach that is based on encryption, as well as authentication.

It was first used in the year 1977 and is based on prime number logic. It is basically a fast approach that can handle multiple operations at a time. However, if the key size is small, it generally performs its operation slower.

Ques 10. Name the elements of a cryptography tool?

There are basically three important elements.

The first is the sender which in fact also encrypts the information in a secured form.

The other is the receiver where information is received and decoded.

The third is the channel in fact which connects both sender and receiver.

Most of the attacks for data-stealing are made on a channel only. This is the reason that why data or information on it always remains in a coded form.
