What it is

Obsidium protects 32-bit and 64-bit Windows software and games against reverse engineering, unauthorized modification, and redistribution while adding licensing controls. It handles native EXE, DLL, and SCR files plus .NET Framework 4.x executables, supporting Windows XP through Windows 11. Selected native code can be converted into bytecode for a virtual CPU. Licensing uses RSA or elliptic-curve cryptography, with expiration dates, hardware locking, and code encryption tied to licenses. Time trials can end on a date, after days or executions, or after specified application actions. Security tools include integrity checks, encrypted data files, anti-disassembly and anti-debugging measures, and license-key blacklisting. An SDK provides examples for C/C++, Delphi, Rust, C#, Visual Basic, PureBasic, and other languages. A key-generation library is available as a Windows DLL and Linux CGI. Network Licensing distributes floating licenses through a local corporate-network service. Obsidium is paid, has no free plan, and offers a free trial.
