  1. Cipher

    In cryptography, a cipher 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 from plain text into code or cipher. In non-technical usage, a "cipher" is the same thing as a "code"; however, the concepts are distinct in cryptography. In classical cryptography, ciphers were distinguished from codes. Codes operated by substituting according to a large codebook which linked a random string of characters or numbers to a word or phrase. For example, "UQJHSE" could be the code for "Proceed to the following coordinates". When using a cipher the original information is known as plaintext, and the encrypted form as ciphertext. The ciphertext message contains all the information of the plaintext message, but is not in a format readable by a human or computer without the proper mechanism to decrypt it. The operation of a cipher usually depends on a piece of auxiliary information, called a key. The encrypting procedure is varied depending on the key, which changes the detailed operation of the algorithm. A key must be selected before using a cipher to encrypt a message. Without knowledge of the key, it should be extremely difficult, if not impossible, to decrypt the resulting ciphertext into readable plaintext.

Rap Dictionary

  1. cipher(noun)

    In hip-hop parlance, the term refers to something like a jam session in which everyone contributes to the creative experience. Be they DJs, dancers, rappers or graffiti writers, all the different artists that collectively make up the culture of hip-hop can have their own cypher. When dancers cypher, you’ll see each taking a turn in the center of a circle, contributing a unique style, then resting. The center of circle is never empty and the energy of the cypher grows as the dancers push themselves into increasing levels of athleticism. Rappers cypher together huddled in a corner, rhyming a capella to handclaps or any ambient beats in the surrounding environment. "I was walkin' down the street about three o'clock, when I saw another MC at the end of the block, talkin' to kids tellin' em, how they had to get the dough, so I rolled right up in the cipher and said 'Yo!'" -- K-Os (Freeze)

  2. cipher(noun)

    A pot-smoking session, or rotation. "yo can i get in on this cipher?"
