SignetSure
This software is Win32 security tool for protecting files from hacker alteration. You create digital signatures for your files from a Win32 app. Then you authenticate your files with a single API call. Authentication code is available both in dynamic (DLL) and static (LIB) library formats. Use either C/C++ or Visual Basic.
SignetSure uses RSA public key cryptography. Download free demo version, which has no time limit.
