I might be biased, but I think that it is brilliant. Don't be confused by the ridiculously low price, because this CD-ROM contains tons of fascinating and dynamic material, including: 1. Encryption tools, 2. Code breaking tools, 3. Coded messages to crack, 4. Material for teachers, e.g., worksheets, 5. A realistic, virtual Enigma cipher machine, 6. A beginner's cryptography tutorial, 7. A history of codes from 1000BC to 2000AD, 8. Material for junior codebreakers, 9. An animated section on quantum cryptography, 10. Sections on public key crypto & RSA. The CD-ROM is ideal for teenagers, parents who want to encourage an interest in science and mathematics in their children, grown-ups interested in the history of cryptography, amateur codebreakers and anybody who wants to know about encryption in the Information Age. The CD-ROM is compatible with PC computers, but not Macs. I have this CD-ROM and I will tell you it can teach you a lot!

It is a simple shotgun, hill-climbing algorithm that allows you to specify a crib. It doesn't care about word breaks and ignores them in fact. One of the most useful parts is the scoring function in score_words.c. It scores a plaintext based on the words it finds. I use this algorithm in a majority of the cracking programs I write. Sorry if the code is a little ugly and has hard-coded buffer sizes. I just wrote it for myself. Apparently the file is too large to upload because it includes the dictionary. You can download it from http://www.wutka.com/download/msolve.zip

It's hard to call anyone stupid who is interested in cryptography. I think Insecure's code was written for Microsoft Visual C++ You can open it up in any text editor, of course, but to actually compile and run it you'll need something like Visual C++.

A .c file is a C source file. You'll need to compile it using a C compiler. Your choice of compiler depends on your platform -- are you using windows, linux, mac, or other? Pulsar

If you don't want to compile it, I can send you the .exe, but you'd miss out on a valuable programming learning experience! If you'd like to go ahead and try to compile it, I'd recommend Dev-C++. It's free from here. Just start it up, load the .c file and then look for a build option. It's been a while since I've used it (I use MSVC++) but it's pretty much the same no matter what IDE you use. If you'd like me to email you the binary, let me know your email address in a PM. Pulsar

Well, no, it wasn't written for Visual C++. In fact, it's an ISO C program, so it was written for everything everywhere. But yes, it will work with Visual C++, invoked in C mode. I generally don't bother with Visual C++. I can't see the point in using Microsoft software (including Windows). I prefer stuff that works.

I saw a comment in there about MSVC so I just made a bad assumption.

I saw a comment in there about MSVC so I just made a bad assumption. No, no insult at all. The MSVC reference was out of sheer exasperation at the stupid stupid warning I was getting when testing this on Windows (yes, that's one of the few uses I have for Windows - basic portability testing). I am not one of these people who shuts warnings up without understanding them, by the way. But in this case I fully understood what MSVC was saying, and I was thinking "but that can never, ever happen in this case, because...", and I made absolutely sure I was right. But trying to explain all that to MSVC in a portable way, without a cast, was beyond me.
