WebIt is also known as the Honorian alphabet or the Runes of Honorius after the legendary magus (though Theban is dissimilar to the Germanic runic alphabet ), or the witches' alphabet due to its use in modern Wicca and other forms of witchcraft as one of many substitution ciphers to hide magical writings such as the contents of a Book of Shadows … 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. In common parlance, … See more Originating from the Arabic word for zero صفر (sifr), the word “cipher” spread to Europe as part of the Arabic numeral system during the Middle Ages. The Roman numeral system lacked the concept of zero, … See more There are a variety of different types of encryption. Algorithms used earlier in the history of cryptography are substantially different from modern methods, and modern ciphers can be classified according to how they operate and whether they use … See more • Autokey cipher • Cover-coding • Encryption software • List of ciphertexts • Steganography See more In casual contexts, “code” and “cipher” can typically be used interchangeably, however, the technical usages of the words refer to … See more In a pure mathematical attack, (i.e., lacking any other information to help break a cipher) two factors above all count: • Computational power available, i.e., the computing power … See more • Kish cypher See more
