Articles relating to ciphers, algorithms for performing encryption or decryption.To encipher or encode is to convert information into cipher or code. In common parlance, "cipher" is synonymous with "code", as they are both a set of steps that encrypt a message; however, the concepts are distinct in cryptography, especially classical cryptography.
Most of the Japanese ciphers listed in the previous list (except for Camellia) have moved from the "Recommended Ciphers List" to the "Candidate Recommended Ciphers List". There were several new proposals, such as CLEFIA as a 128 bit block cipher as well as KCipher-2 and Enocoro-128v2 (Hitachi) as stream ciphers. However, only KCipher-2 has been ...

Heath Robinson was a machine used by British codebreakers at the Government Code and Cypher School (GC&CS) at Bletchley Park during World War II in cryptanalysis of the Lorenz cipher. This achieved the decryption of messages in the German teleprinter cipher produced by the Lorenz SZ40/42 in-line cipher machine.
