Encrypt Text

I honestly can't think of any way to improve it. It's exactly what I wanted

I just tried a port to C++, and got a few errors. In fact, my top error was this:

Warning    102    The maximum number of errors or warnings has been reached.    C:\Program Files\MSBuild\Microsoft.Cpp\v4.0\Microsoft.CppBuild.targets    1542    1    Miscellaneous Files

Why did you try and port it to C++?

Tom

Because I am not very good with C++ (did I need to tell you that? ) and I wanted some practice!

Haha. Just out of interest, what encryption algorithm does this tool use? Is it RSA?

Triple DES because it fits neatly with an MD5 hash converted to bytes.

To keep the code above straightforward we made use of the fact that an MD5 hash is exactly 128 bits in length. The C# TripleDES code accepts three possible key lengths: 64 bit, 128 bit and 192 bit. Only 192 bit keys are truly TripleDES, the 128 bit key length we obtain from the MD5 hash is only sufficient for Double DES. According to Wikipedia, that would make its real key strength only equivalent to 80 bits.

^^ As you can see, not real TDES. When I make my own little password hasher, I shall either up it to proper TDES, or use RSA. Undecided at the moment
