Hi codeX,
what do you mean of "signature of Deploy.NET" ? may be I don't know something so I can not undrestand what you mean.
If you mean key of encryption of assembly resource, of course there is a private key inside deploy.net assembly, but I didn't tried to find it out.
BTW, I found only Decompiler.NET that is encrypted with Deploy.Net, but both of them are from same company
It seems like Deploy.NET have only trial version !!

, even Decompiler.NET that is from developer of Deploy.NET shows a dialog box that says " This app is protected by trial version of Deploy.NET" when you start it !!
