Talk:Chaocipher

message: 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.

message: * The article states At least three people know how it works: Byrne's son, and two of the editors of Cryptologia during 1990. Byrne, however, is now dead, so his secret is lost with him. If 3 people other than Byrne know how it works, how can the secret have died with him? Paste  Let’s have a chat. 22:16, 30 January 2009 (UTC)
replies: text: I've deleted the sentence that claimed the secret is lost, as it contradicts a referenced source that says three people know it. Autarch (talk) 20:25, 13 March 2009 (UTC)
thread_title:  Confusion? 

message: David Kahn mentions Byrne and his "chaocipher" in The Codebreakers , which is good enough for me to believe in its existence, but how strange that Googling is turning up so very little information aside from Wikipedia mirrors and blog "top ten lists" of ciphers. Does anyone have an actual sample of any of Byrne's challenge cipher texts? 151.197.226.214 (talk) 05:34, 12 February 2009 (UTC)
replies: text: Great minds think alike!  To rectify the paucity of Chaocipher-related material on the Web I built a web site called "The Chaocipher Clearing House" .  You'll find there carefully edited ASCII versions of Byrne's challenge exhibits, chapter 21 from "Silent Years", a summary of Chaocipher research to date, references to articles, and my own research results.

thread_title:  So little info... 

message: The used link to "J. F. Byrne" is wrong! This is the wrong man!
The inventor of chaocipher "J. F. Byrne" was born in Dublin, 11. Feb. 1880 and died 1960 in USA. He was a friend of James Joyce. He wrote an autobiography called "Silent Years".
Please correct this. Best wishes.
