For anyone who wants to experiment with sliding tile ciphers, I put up a javascript ap that lets you try out different shuffling procedures to see how well they mix the alphabets. @novice: now you can try out different autokey-type scrambling schemes you proposed on the "homemade cipher machines" thread. Here it is. I've been having fun with it. http://cryptopian.com/tile_slider/slide_15b.html On Edit: here's one technique I tried: Start with the alphabet arranged properly. The first plaintext is N. Below N is T. Click the right end of the horizontal row with N (R) Click N. Click comma. Click 9. Now the empty slot is back in the lower right. Now click F, A, period, 3 to cycle the outside edges and put the empty slot back in the lower right. Repeat this with each plaintext letter. Next plaintext is O, and below O is V. Cycle the O-L-blank-9 rectangle, (click L-O-9-X) then cycle the out edge by clicking E-G-dash-R. Repeat with the next plaintext, and continue until the message is enciphered. When the plaintext letter is on the righthand column or the bottom row, just do the outer edge cycle, since there is no rectangle to cycle.

@ fiziwig This is a great app -- graphics are sharp and beautiful, interactive function works well and the implementation is perfect. |

Thanks. That's an interesting one too. I was thinking of doing some of my other sliding tile ciphers as javascripts too.
Thanks. I haven't done any programming in a while, so I was pretty rusty. I copied some of the code from another sliding block puzzle ap I found. I thought I might try a 6 x 6 block (A-Z;0-9} with no empty cell. You could use a keyphrase to do the shuffling like this:
I'm definitely going to do this one in javascript. I think it would work out pretty good. Edited by fiziwig, Jan 30 2014, 06:32 PM.

OK, here's a 6x6 sliding tile shuffler that seems to do a really good job of scrambling the alphabet based on a keyword: http://cryptopian.com/tile_slider/slide_36.html Instructions are on the page. |
