- The encrypted plaintext is called the ciphertext or cryptogram and the set of rules used to encrypt information plaintext is the encryption algorithm. Normally the operation of this algorithm depends on an encryption key, which is input to the algorithm together with the message.

Cipher, any method of transforming a message to conceal its meaning. The term is also used synonymously with ciphertext or cryptogram in reference to the encrypted form of the message. All ciphers involve either transposition or substitution or a combination of these two mathematical operations.

Cryptography is the practice of developing and using coded algorithms to protect and obscure transmitted information so that it may only be read by those with the permission and ability to decrypt it. Put differently, cryptography obscures communications so that unauthorized parties are unable to access them.
Cryptography is a method used to protect data by converting it into unreadable formats, rendering it incomprehensible to humans without the appropriate keys. Modern cryptography relies on engineering concepts, software, cryptographic algorithms (also known as ciphers), and mathematical concepts to encrypt and decrypt data.
Codes generally operate on semantics, meaning, while ciphers operate on syntax, symbols. A code is stored as a mapping in a codebook, while ciphers transform individual symbols according to an algorithm. Now, let’s review the mechanics involved in the Caesar Cipher in the next exercise. Questions.

In cryptography, ciphertext or cyphertext is the result of encryption performed on plaintext using an algorithm, called a cipher. [1] . 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.
In cryptography, a cipher (or cypher) is an algorithm for performing encryption or decryption —a series of well-defined steps that can be followed as a procedure. An alternative, less common term is encipherment. To encipher or encode is to convert information into cipher or code.
Cryptography. Cryptography, as defined in the introduction to this article, is the science of transforming information into a form that is impossible or infeasible to duplicate or undo without knowledge of a secret key. Cryptographic systems are generically classified (1) by the mathematical operations through which the information (called the ...
