Solve : Crypt & UnCrypt - C++ Programming - Sharing Project?

Answer»

Decided to share a project I was playing with. During the cold winter months I like to dive into programming and had been thinking about playing around with scrambling and crypting info for a while. These Crypt and unCrypt programs are not complex and are very basic crypt with character substitution. This is pretty easy to crack to decrypt because its just substitution and repeat characters also show as repeats in the crypted form.

From here on I plan on making it even more complex where there are more than one key so it starts from multiple places in the Random Algorithm and each character within the string that is input is assigned to substitution from a different shuffled group of characters meaning that if you saw 2 characters alike paired, you will not be able to decrypt it so easily because a pair of characters are unlikely to be substitution for the same character.

I am using the Bloodshed Dev C++ 4.9.9.2 IDE. If you use a different IDE you might need to edit it some. Such as I use to program using Borland C++ 5.02 IDE years ago and when taking that source code to Microsoft C++ 6.0 I had to edit it some to get it to compile.

The code shared works and I need to clean it up, but still has some commented out debug and a -1 offset for a mistake I made which I plan to correct to remove the -1 offset. The mistake was that arrays start at 0 and not 1. I wrote the lengthy IF ELSE logic without having even created my array yet and right away I knew there was a problem when I got a mismatch between my input and output. The quick fix vs going through and editing all my IF statements was to just place a -1 offset so that it targets the array for the correct character place from the string. Once I fix the IF statements I can remove this -1 offset band aid.

These crypt and uncrypt programs support only these characters:

ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklm [emailprotected]#$%^&*()_-+=?<>:\/~.,;

And this character ` is used as an option to end the program, however you can also end it by closing the window or keystroke kill command.

You can add more characters if necessary, but in doing so you need to add the IF statements to support the additional characters.

The array size I set to 128. It could be set to the bare MINIMUM but 128 is ok because it only wastes a very small amount of RAM.

If anyone has any suggestions to improve the code or wants to build on from this, please feel free to do so and share changes here with notation or comments in the code. Lastly I am not a professional programmer its more of a hobby, so if your a professional programmer and you see something that is like nails on a chalk board in my code, I'm sorry and it wasnt done intentionally to be painful to read in the source, its just that there are many ways to achieve the same desired output and programming is sort of like an art and everyone has their own style sort of. My style seems to follow an abstract Rube Goldberg at times as for I need my code to do something and at times I will achieve my goal and once compiled no one would really know the difference really, but the source code tends to be blocked together of different pieces that make it work which may not be the most efficient or hold to a coding standard.

[attachment deleted by admin to conserve space]Cleaned up code ... removed unnecessary junk from source and corrected for the +1 offset to IF logic pointed incorrectly with starting position at 1 vs 0 for array. Corrected to start at 0.

Below highlighted is input information from user and green is the output.

}Looks cool although you would be much better off using some sort of map data structure instead of that massive block of else ifs. Alternatively you may be able to get creative with the character's ASCII value. This would make the code a lot neater and more compact.Good suggestion ...

Prior to coming up with what I came up with I was toying around with all sorts of dynamic methods of scrambled character substitution to try to make it work with less code, but while its really easy to scramble information with not many lines of code needed, being able to inverse that scramble and bring it back to its original form was tricky. So using 2 arrays one static and the other dynamic was the way to decrypt it back to its original form.

I almost went with SWITCHES instead of IF THEN ELSE, but from years of IF THEN ELSE logic, that method flows easy from brain to keys.

Tonight I was playing around with it writing a single lined entry to 2 files appended... a Key File and a Data File. And I thought all was well, BUT when looking further for some reason I am getting an additional write to file for the scrambled output so instead of an output of say 7*hY I am getting 7*hYY. My solution to fix this might be to have a counter that counts how many characters were entered and only allows the while loop to run equal to the character count. Or have a routine that reads in the last line and TRIMS off 1 character place. But these both seem like sloppy band aids. Its really strange that the output to display is correct without the extra character at the tail end, but the file write instruction processes writing the last character TWICE. This one has me slightly stumped because programmatically I dont see a flaw, but there is one.

It would be possible to replace the else if portions dealing with alphabetic characters with some math.

Upper case characters are codes 65 to 90. Your codes start at 0, so all the blocks testing capital characters can be replaced:

Code: [Select]if(ch >= 65 && ch <= 90)
{
code1 = ch-65;
}
for lowercase characters, they span from 97 through 122, and your cipher maps them at 26:

Code: [Select]else if (ch1 >= 97 && ch1 <= 122)
{
code1 = ch1 - 71;
}
Thanks BC for your input on this... that got me thinking of back in the days many years ago with GW-Basic I used Chr$(ascii_value). http://www.antonis.de/qbebooks/gwbasman/chrs.html And I guess I am reinventing the wheel by assigning my own values to the characters, when I should just be using their already existing ascii identifier which I can get from casting char to an int.

Found this info here that is a big help too, and will correct for the fact that spaces are not accounted for on entry of what is to get scrambled and character substitution.

http://stackoverflow.com/questions/6405137/asc-and-chr-equivalent-in-c-c

output is:
Quote
string = "Hello, World!"
chars = 72 101 108 108 111 44 32 87 111 114 108 100 33

Also found more info here on the code example you gave me:
http://stackoverflow.com/questions/5029840/convert-char-to-int-in-c-and-cFound and fixed the additional character write problem I had. I thought of suppressing the write to file until the start of the first iteration of the loop in which write enable is enabled for the write function. This fixes the issue where upon exit by use of the ( ` ) key it does not write the last character twice appended to the text file.

Now that I have this fixed I can go back and clean up the IF logic mess. And make this program about 80% smaller in size.

The double write bug was really driving me up the wall when it made no sense as to why it was happening. So I decided to force the write to file prior to the ( ` ) exit instruction so that it will exit the loop without passing the write to file instruction before leaving the while loop in which its writing the last input from the input buffer and that idea worked. However I had to suppress writing to file until the characters processed went through the logic otherwise I had a leading array[0] value write to file and it added the first character within the array at the beginning of the file appended. So by this write to file only being enabled after the input was processed through the IF logic, but not after the exit instruction, by use of a write enable flag to start the write enable for the write to file instruction. That fixed it.

Prior to bug fix if you used a seed key value of 43 and entered Hello_World you would get AW\\^nY^H\22 and now with bug fix I get the correct information written to file of AW\\^nY^H\2 ( single last character appended vs double last character appended )

// 1/8/2016 - Source code trash cleanup & offset band aid removed for IF statement logic +1 array offset v1.02
// 1/8/2016 - Added write to file for coded data storage eliminating need to copy/paste output to a text file v1.03
// 1/15/2016 - Fixed Loop writing duplicate character on ( ` ) loop exit with write delay until loop processed prior to write
// - seed of 43 with Hello_World was producing AW\\^nY^H\22 prior when it should only be AW\\^nY^H\2 with a single 2
