|
Encryption
|
|
|
Decryption
|
|
|
Either A or B
|
|
|
None of the above

Explanation:
Detailed explanation-1: -The decryption cipher is an algorithm that transforms the ciphertext back into plaintext.
Detailed explanation-2: -Asymmetric encryption transforms plaintext into ciphertext. Plaintext is transformed into ciphertext using two keys and a decryption algorithm. A major advance in symmetric cryptography occurred with the development of the rotor encryption/decryption machine.
Detailed explanation-3: -Cryptographic ciphers are used to convert ciphertext to plaintext and back. With symmetric key algorithms, the same key is used for the encryption and decryption of data. Asymmetric key algorithms use public keys and private keys to encrypt and decrypt data.
