Can anyone recommend a obfuscator?

We tried Xenocode postbuild but got an error: "This assembly is not strong

name signed." Looks like the message came out of the RunCaspolCommand method

in the CaspolSecurityPolicyCreator.cs of the SetSecurity project.

Can Dotfuscator handle addin and the security challenge?

Any time you obfuscate you must delay sign your assembly and actually sign

it with that SNK or PFX after the obfuscation. Otherwise the

signature/strong naming is also obfuscated along with your code.

Same problem: xxx.dll does not represent a strongly named assembly

Here is what we did:

1. checked "Delay Sign only" while kept "Sign the assembly" check

2. built, got UnsignedAddin.dll

3. ran Outlook, add-in cannot load

4. manualy sign from commoand line OK: ran sn -R unsignedAddin.dll

keyfile.pfx

5. ran Outlook, addin loaded OK.

6. built again

7. obfuscate the UnsignedAddin.dll =>ObfuscatedUnsignedAddin.dll

8. ran sn -R ObfuscatedUnsignedAddin.dll keyfile.pfx

Got error message: obfuscatedUnsignedAddin.dll does not represent a strongly

named assembly

I chekced the article "Giving a .NET Assembly a Strong Name" at

http://www.codeguru.com/columns/experts/print.php/c4643. My procedure was

right.

I then used Dotfuscator Community Edition (not support Office addin) against

a C# console exe, following the same procedure. It worked. Look like

Xenocode postbuild broke the strong name.

What obfuscator do your guys use? How much $?

I rarely obfuscate any of my code, usually I just hand it over to the

customer and they take care of that since they'll be using their own

certificate to sign the code and not mine. On the rare occasions I've

obfuscated my code I've used the full edition of Dotfuscator.

That article looks right, one thing to try would be if you try using an SNK

file instead of your PFX and using that in your post-obfuscation signing

call.
