Obsidium
Bad Lippspringe, Germany
What it is
Obsidium protects Windows software and games against reverse engineering, unauthorized modification, and redistribution while providing licensing controls. It handles 32-bit and 64-bit native applications, including EXE, DLL, and SCR files, plus .NET Framework 4.x executables. Code virtualization converts selected native code into bytecode for a virtual CPU. Licensing can use RSA or elliptic-curve cryptography and support expiration dates, hardware locking, and license-dependent code encryption. Other protections include integrity checks, encrypted data files, anti-disassembly and anti-debugging measures, and license-key blacklisting. The package includes an SDK with examples for C/C++, Delphi, Rust, C#, Visual Basic, PureBasic, and other languages. A key-generation library is supplied as a Windows DLL and Linux CGI, while Network Licensing manages floating-license pools through a local corporate service. Obsidium supports Windows XP through Windows 11. It is paid, uses a perpetual license, offers a free trial but no free plan, and provides email or forum support with updates for 12 months.
