Realizing Decryption of Registration Method by Using Software Reverse Engineering
Bin Wang · Journal of Tonghua Normal University · 2008
Using the software reverse engineering,this paper studied a commercial test system with the aid of dynamic software reverse analysis tool OllyDbg and detection tool PEID.Then the execution process of this software's registration method was calculated.Based on this,its encryption algorithm and the method of verifying register code were analyzed,and the declassification was realized successfully.
