Detailed explanation-1: -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-2: -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-3: -d) decrypted message. Explanation: Cipher is a method to implement encryption and decryption of messages travelling in a network. It’s used to increase the confidentiality of the messages.
Detailed explanation-4: -Ciphertext is also known as encrypted or encoded information because it contains a form of the original plaintext that is unreadable by a human or computer without the proper cipher to decrypt it.
