algorithm for transforming plaintext to ciphertext
|
Detailed explanation-1: -Ciphertext is encrypted text transformed from plaintext using an encryption algorithm. Ciphertext can’t be read until it has been converted into plaintext (decrypted) with a key. The decryption cipher is an algorithm that transforms the ciphertext back into plaintext.
Detailed explanation-2: -A cipher algorithm is a mathematical formula designed specifically to obscure the value and content of data. Most valuable cipher algorithms use a key as part of the formula. This key is used to encrypt the data, and either that key or a complementary key is needed to decrypt the data back to a useful form.
Detailed explanation-3: -What is transformed using cipher algorithms? Answer: C) Plain text is transformed using cipher algorithms.
Detailed explanation-4: -Encryption: The process of converting plaintext to ciphertext using a cipher and a key.
