v. To calculate arithmetically. (also a noun meaning zero or nothing)

Any cryptographic system in which arbitrary symbols, or groups of symbols, represent units of plain text or in which units of plain text are rearranged, or both. [INFOSEC-99] 2. The result of using a cipher. Note: An example of a cipher is an enciphered message or text.

A security 'tool' for protecting transmitted (usually by wireless) information.

In cryptography, a cipher is an algorithm that can encode cleartext to make it unreadable, and to decode it back. Ciphers were common long before the information age (e.g., substitution ciphers, trans [..]

An algorithm or system for data encryption. Examples are DES, IDEA, RC4, etc. See: SSL/TLS Encryption

To dream of reading cipher, indicates that you are interested in literary researches, and by constant study you will become well acquainted with the habits and lives of the ancients.   

A cryptographic algorithm used to encrypt data that is unreadable until converted into plain data with a predefined key.

  The algorithm used for the encryption and/or decryption of information. In common language, 'cipher' is also used to refer to an encryption message, also known as 'code'. (Wikipe [..]

Ciphers are codes for writing secret messages. Two simple types are shift ciphers and affine ciphers. circle

In cryptography, the word cipher refers to an encryption algorithm. A cipher transforms the original data/message into pseudo-random data/message of the same length. In order to decipher the message [..]

Any method used to turn plain text into an unreadable and meaningless form. Ciphertext is text that has been encoded into this unreadable form. This often involves the use of a mathematical formula to [..]

A cipher (or cypher) is an algorithm for encrypting or decrypting information. A cipher may be very simple (e.g. simple letter substitution) or mind-crushingly complex (e.g. Elliptic curve Diffie-Hellman, which I won't even try to explain here!), but the aim is the same - to prevent information being readable to anyone intercepting it.

  A cipher is the generic term used to describe a means of encrypting data. In addition, the term cipher can refer to the encrypted text itself. Encryption ciphers will use an algorithm, which is the complex mathematical calculation required to 'scramble' the text, and a 'key'. Knowledge of the key will allow the encrypted messa [..]
