Encryption is the conversion of data into a form, called a ciphertext that cannot be easily understood by unauthorized people. Which encryption is the strongest by use of mathematical evaluation techniques?
A. ROT13
B. AES
C. DES
D. 3DES

B. AES

Explanation:

Encryption is used in securing important data and folders. It makes use of passwords and prevents unauthorized people from access to it.

AES is known as Advanced Encryption System and was developed by two Belgian cryptographer Vincent Rijmen and Joan Daemen.This encryption type took over the DES system and is used worldwide in top government and private informations because of its higher data security system through the use of symmetric algorithm. This symmetric algorithm uses the same key to encrypt and decrypt the sensitive data.
