How to add strongname signature(SNK) to protected .Net DLL?

2

With Strong Name Tool.

3

.Net dll after protected with VMProtect， can not resign strong name.

4

Why?

5

After VMProtect protection, the DLL file that has been strongname signed will be invalid.

Adding a Strong Name to an existing DLL， need
ildasm SomeAssembly.dll /out:SomeAssembly.il
[and]
ilasm SomeAssembly.il /dll /key= keyPair.snk

But protected DLL cannot ildasm

6

Did you try to resign your binary with sn.exe?

7

It’s been tried, but can’t resign with “sn.exe -R ”

8

What does “sn.exe” show?

9

show “dll does not represent a strongly named assembly”

=====================================================
Comment:
1、When the dll file is protected by VMprotect, the strongname signature becomes invalid.
2、When using "SN.exe -R " to resign dll file, the original strongname signature is required to be the same and valid.

Hi,

After I resigned the dll using "SN.exe -R ", I used gacutil /IF “protected dll file” and got the following error:

“Failure adding assembly to the cache: Invalid file or assembly name. The name of the file must be the name of the assembly plus .dll or .exe”"

Thanks!
