Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What is a Ciphertext?
A
Encrypted message
B
Text used to encrypt messages
C
Message sent by sender to recipient
D
Decrypted message
Explanation: 

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: -Definition: Cipher is an algorithm which is applied to plain text to get ciphertext. It is the unreadable output of an encryption algorithm. The term “cipher” is sometimes used as an alternative term for ciphertext. Ciphertext is not understandable until it has been converted into plain text using a key.

Detailed explanation-3: -In computing, unencrypted data is also known as plaintext, and encrypted data is called ciphertext. The formulas used to encode and decode messages are called encryption algorithms, or ciphers. To be effective, a cipher includes a variable as part of the algorithm.

Detailed explanation-4: -Ciphers, also called encryption algorithms, are systems for encrypting and decrypting data. A cipher converts the original message, called plaintext, into ciphertext using a key to determine how it is done.

Detailed explanation-5: -If you can make sense of what is written, then it is in plaintext. Ciphertext, or encrypted text, is a series of randomized letters and numbers which humans cannot make any sense of. An encryption algorithm takes in a plaintext message, runs the algorithm on the plaintext, and produces a ciphertext.
