Talk:Chaocipher

From Wikipedia, the free encyclopedia

The article should clarify whether chaocipher is: (a) a *cipher* (which could be implemented in various ways, including but not limited to a physical machine), or (b) a *machine* whose internal construction must be kept secret. If it is (a), a modern cryptographer would still be interested in solving it. But if it is (b), no modern cryptographer would be interested in solving it: a fundamental requirement of modern cryptography is that the details of the cipher must be openly published for all to see.
