Hi,
I'm not so newbie on Reverse Engineering. But my last reverse engineering was done with SoftICE, about 15 years ago...
So, I'm working on study about FlexLM protection. I've a software that using a License File in XML format.
This file have some tags for configuring the features enabled. One last tag is the Signature, an alphanumeric string 120 bytes long. This Signature is based on content of this license file itself, and surely using some Key...
There are some libraries used by the Software License Center, one of this is a FlexLM DLL Library, and a command line tool to check the License File using this DLL Library.
Usually I use W32Dasm to disassemble any Executable File, EXE or DLL files. This file has not analyzed from W32Dasm, without any errors. I want to know the mechanism to check the signature of this file. I need of an help to choose the right tool to made it.
I've used OllyDbg 2.0 to made some reserve engineering, but the software check the presence of Debugger. I've tried to use some plugin like Stealth64 enabling quite all available protections and hide OllyDbg, without success.
I want to disassemble this DLL to made a study on reverse engineering on the function for check Signature. What can I used?
