So shouldn't the code be signed, not encrypted since you should still be
able to see the code, just not change it.

I assume you are talking about your stage 2 implamentation, right? Unless
I'm wrong about VB there is a problem with your method. In order to go from
source code into compiled code you need to first parse the code, create IL
tokens and then create an executable file based on that. Your program would
need to decrypt the code into plain text inorder for VB to compile it. So
at somepoint the plain text has to be in the system.
Also this means that the key to decrypt the code is also stored in the
system since it needs to be able to decrypt the code in order to compile it.
So with the key and plaintext stored in memory it seems like you are
depending on security through obscurity which is not secure.

So are you creating your own interpreter to interprete the source code at
runtime? Or are you decrypting the source code, compiling it, and then
reencrypting the executable file?

What type of file does it compress? Normal text files are different from
binary executables, and source code is probably more compresible then normal
