Question

Discuss:

Primary objective of using encryption algorithm

Answer 1

Answer is as follows :

The encryption is used to protect digital data confidentiality i.e. transferred over the network through various links. Encryption is used to convert given data to some protected data known as cipher text. So that if the data is hacked, the third party can't access the original data.

So for this encryption we need some methods, some technology. So we use Encryption Algorithm to encrypt the data so our confidential information don't leaked even if it is hacked. Data is encrypt by some key ( that can be in numbers, binary numbers etc).

For proper identification of that key and efficient use of key, we need some proper steps that are defined in encryption algorithms.

So Encryption Algorithms are needed for Encryption/Decryption.

Some of Encryption algorithms are RSA , AES , DES etc.
