Talk:Straddling checkerboard

The example given of adding a number and then going backwards seems to have a flaw.

Consider if "62" came up after the non-carry addition. When you tried to go back to letters, what would you do? There's no letter you can put down for this.

Fixed. I added in a forward slash, sometimes used to signify a change from letters to numbers and back again, for 6-2 so that you can always go backwards now.

Actually, I believe that empty box was supposed to be a space... There is still a problem that means you can't always go backwards. What if the end of the string was "06"? You'd get an E, and then not know what to do with the 6. This can trivially be caused by changing the key in the article from 0452 to 0451. 82.33.61.156 (talk) 13:12, 10 June 2009 (UTC)

merge
I suggest merging the "straddling checkerboard" section of the VIC cipher article into this straddling checkerboard article, leaving behind a very brief Summary style summary of and link to the "straddling checkerboard" article. --68.0.124.33 (talk) 15:16, 10 August 2009 (UTC)

Oops
The edit on 00:48, 3 February 2010, from User 72.95.65.182, was actually me. I thought I was logged in but I wasn't. Sorry! --Doctorhook (talk) 00:53, 3 February 2010 (UTC)

Refactoring
I've split this out from the VIC Cipher. As the VIC Cipher page needs a re-write (which I plan to do). However (the VIC Cipher) is complex enough without needing to explain the Straddling Checkerboard. As the Straddling Checkerboard is a cryptographic entity in its own right (historically and mechanically) to the VIC Cipher it should have its own page Zasmkl (talk) 13:41, 12 January 2020 (UTC)
