Obfuscator and my acad plugin dll app

[jaboone]

Not sure if anyone can help if they don't have this software, but am going to try.  Maybe someone knows.

I use logic NP obfuscator and am trying to compile a dll plugin I am wanting to send on the app portathon, so I need an answer as soon as possible if anyone can share some insight.

Obviously there is some obfuscating in the acad support files, that I guess mine is bucking with.  This is the error message I am getting.  I tried to ignore the acad stuff.

[jaboone]

Resolved, sorry.

[santoshr0114]

Can you tell how?

[jaboone]

You have to own a Obfuscator, but most arn't cheap, in the $2500 range, but I was able to find one, LogicNP, out of India for less than $300.  Tell them James Boone sent you.

The product is relativly easy to work, once you learn all the neances of obfuscation and the terminology.

[santoshr0114]

Thank You for the information, But how did u solve the error.

[tamilanban]

Consider two dependent Projects in your solution .A and B , if A.DLL alone is builded and updated in crypto obfuscator then the the references to B.DLL are not got from the metadata from the obfuscator
..... so consider the whole solution always before obfuscating the solution .

[jaboone]

The obfuscator I have compiles both at the same time.  Actually I have to take special efforts to remove any I don't want compiled.

[jaboone]

Remove the acad dll's from the solution. Told it not to compile acad dlls.

Hi folks

I'm sure someone will be going through the same problems in the futre. So perhaps I will write a blog post about it once I have the solution.

Context

I have written a dll. I do not want staff/colleagues running off with it. If they do I don't want to make it easy. I am using CryptoObfuscator to obfuscate the dll.

1. First I clicked on "add Assemblies". I then added the dll which visual studio produced in the bin/release folder.
2. Then i clicked on some "obfuscation settings"
3. Then I clicked on "obfuscate"

and it throws up the following screen - which looks exactly like the error James Boone had above.

Jame's solution:

• Unlike James Boone, in CryptoObfuscator, I did not reference any Autocad Dlls. But within the DLL which I made, there are references to AcDbMgd etc. 
• Am I doing this right? Any help would be much appreciated.

Here are my crypto settings:

I"m using Autocad 2016. And I have made a .net DLL that degubs perfectly. It just can't seem to obfuscate it. any help would be much appreciated.

kind regards

BK

BK, I don't use CryptoObfuscator so have no idea where you need to add this setting, but, just as the message implies, you need to provide a location for the AcDbmgd.dll (and any other referenced assemblies you use in your builds. In Dotfuscator we have a setting for "User Defined Assembly Load Path" where I specify paths to the Acad, Map, & C3D *mgd.dll's. Without those paths set I get the same error you do.
