    Question Program working perfectly in Netbeans, but not once compiled (probably a charset problem)

    Hi all,

    I'v been coding myself a little program for a while now, which uses a lot of different encryption algorithms and salts, of which some i coded myself, in a random order. This works like a gem, when it runs in Netbeans, but once i compile it to a .jar file, and try it, it breaks. (encrypted text cannot be fully decrypted, and some of the letters are unreadable).
    This is what i deducted so far:
    * All the encryption algorithms separately are working perfect. They can be stored in a string object, and decrypted from there again, without problem.
    * All the binary encryptions (aes, twofish, serpent etc) work perfectly, even after compiling

    My guesses: when encrypting a character with xor, cesar, etc, there might be this problem:
    char: 0101 1001
    pass: 1100 1011 xor
    result:1001 0010
    some char encodings don't use the first bit of the byte, therefor resulting in a different char then intended.

    Some other info about my code:
    To get a random order of encryptions and salts, a randomizer makes a random order of 4 encryptions. Each of those has a binary number (00, 01, 10 and 11), which is put in that order into a char, that is added in the string, after applying those encryptions/salts. (again, the problem with the first bit might apply here as well, if that is the problem)

    I think the problem might be that the standard charset in Netbeans might not be the same as in Windows (for example UTF-8 vs EBCDIC) and that the Java virtual machine uses the charset of Windows, once the program is compiled.

    Does anyone have an idea of what the problem might be and how to solve it?

    Thanks in advance,

    PidgeyL

    Can you make a small simple program that compiles, executes and shows the problem?

    Do you mean filling it with System.out.println's? I did that, i'll show you an example of an output:
    Here is the "proof" that the encryption methodes work seperately (these are only the string encryptions) Link
    Here is the output of the encrypting and decrypting: Link
    I added a red line to indicate where the output from the encrypting stopped and where the decrypting started

    Do you mean console output of what happens? Compiling does not give errors (only a warning that BASE64 may be removed in future versions) I have two console outputs i made for checking, i'll list them here:
    Encrypting and decrypting: imgur: the simple image sharer ( red line indicates the end of the encrypting output and the start of the decrypting output)
    "proof" that all separate encryptions work: imgur: the simple image sharer
