AZdecrypt 1.19

If you can then let it run overnight with 6-grams to be sure. I still need to speed optimize the row bound solver, it's kinda slow. While at it I should probably add 2-grams and 7-grams as well.

Here's a cipher I made that simulates your example.

O.k., I will try that and see how long it takes. I have company arriving on Friday night, but I get up early in the morning 7 days a week, and will hopefully make some posts this weekend while my company is sleeping. Maybe sooner. Thanks a lot.

I let it run all night and got a partial solution that I can identify by looking at the longest strings where there are long words.

i have altered the bottom section using lower case
i will work on it more smokey if you think it helps.
after lots of work my best guess with google assist . walter white breaking bad


and finally google was my friend.
Mild-mannered high school chemistry teacher Walter White thinks his life can't get much worse. His salary barely makes ends meet, a situation not likely to improve once his pregnant wife gives birth and their teenage son is battling cerebral palsy. But Walter is dumbstruck when he learns he has terminal cancer. Realizing that his illness probably will ruin his family financially, Walter makes a desperate bid

i will work on it more smokey if you think it helps.

Not this time, but definitely some assistance next time if you are interested. I am working on something like the above for the 340, which probably won't work, but I need to do it anyway. The message won't necessarily carry over from one line to the next though, so it will be harder.

[masootz]

is overnight usually sufficient to run azdecrypt on a cipher to see if it's getting somewhere?

[Jarlve]

Nice work on that cipher smokie and Mr lowe, it is pretty hard actually. Also look at the PC-cycles stat, if the 340 is cyclic as we think it should really jump allot when AZdecrypt finds a partial solution.

is overnight usually sufficient to run azdecrypt on a cipher to see if it's getting somewhere?

It depends. If the 340 would be the same as the 408 then it should find a solution nearly instantly. When there are other factors complicating the cipher then it could take a longer time depending on the multiplicity, cipher scheme and the speed of your computer.

no problems happy to help' just pm me when its up so i dont miss it . cheers

I have totally rewritten the row bound solver with optimization in mind and it now runs almost as fast as the other solvers. 2-grams have been added plus 7-gram support and other improvements to the calculation method. Because of that, the 408 with rows of 3 characters that I showed earlier improved from being 55.63% accurate to 57.10%. And the Breaking Bad cipher for smokie has improved from being 74.41% accurate to 84.70%.

The cool thing is that it would now be possible to link it to the any of the transposition solvers. Especially the columnar rearrangement solver could benefit from that.

[masootz]

is there a thread for submitting homemade ciphers for analysis? if not, is there any interest in us laymen trying to fool you guys? i've let my idea run through azdecrypt for over a day without solving, but i'm concerned i may be missing some obvious setting that solves it in five minutes. i also get lost in some of the period analysis stuff so, if there is something i'm overlooking that makes it easy to decipher, i wouldn't mind being able to go back and retool the idea to make it harder.
