I still very much wish to work on my cipher type identification project. But it may be a while before I have enough time to work on it, since I have taken up some paid part-time work related to crypto.

That sounds great, getting paid for what you love to do. And in the meantime you are building up energy and ideas for your cipher identification project.

Very true. I wish I had the resources to put together a team and have them bring the ideas to reality for me!

Another upcoming project: I was invited to give a talk at this year's American Cryptogram Association convention, and thought it would be worthwhile to present to them the latest snapshot of what people think are the significant features of Z340, and what ideas they are testing out especially here in this forum. I've been following everyone's progress here with great interest. I think it would be beneficial to connect this community with the ACA since they have talented codebreakers and I am really curious what they would make of all the weirdness in Z340, especially since they are very familiar with a broad variety of encipherment systems.

You will talk about the 340? It would be worthwhile to know the opinions of the ACA people on the 340 and perhaps our observations.

Yes, I will try to focus primarily on Z340. I'm eager to hear what they think. They spend a lot of time creating and solving all sorts of cryptograms in the magazine they publish every two months. The members seem very competitive, and track the scores of top solvers. Several have even written their own hillclimbers for cracking the codes. I'm hoping that giving them an overview of all of our observations will fuel their curiosity and motivation for exploring Z340.

Several ACA members also post their own homemade cryptograms in this Google Plus group: https://plus.google.com/u/0/communities ... 1588941207

It is good, the 340 feels more than genuine enough to receive more attention.

Made this image for the main page, it looks neat.

Working on a new solver in the midst of things, substitution + sequential homophones. Use the sequential homophones aka cycles as leverage. I have something up and running and it works unbelievably well. It runs about 7 times slower due to the added cycle calculations though ciphers with cycles solve quicker and better. Here are a few examples of what it did so far:

Solve on a 5 row 408 with 6-grams, AZdecrypt's previous best was 6 rows with 7-grams:

Code: Select all

Score: 24955.60 Ioc: 0.05714
Ngrams: 55 PC-cycles: 461

Wow! Nice job! That's particularly impressive since the first 5 rows have a multiplicity of 0.588. More than half of the symbols are different!

Looks really great Jalve!! Great work! I wish that I had the knowledge and ability to use these great programs you all develop.
