Well, I still think that my pattern sweep can tell whether you've got a good transposition or not.

A transposition with keylength < 10 is cracked in about 10 seconds. That means that the pattern sweep takes about 15 seconds. That's do-able.

When you've got a pattern match, solve the mono sub using frequencies.

In theory it sounds like the ADFGVX can be brute forced in an acceptable amount of time. I want to make a C application that does all of the above.

Since most of us are programmers, we can find ways to optimise it.

And I note, NO ONE really made attempt on my challenge, even the known plain text one.

Well, we all hate fractionating systems, for obvious reasons :P I'll have a look at it again when we have brute forced the ADFGVX cipher.
