What Obsidium is

Obsidium protects 32-bit and 64-bit Windows applications and games against reverse engineering, unauthorized changes, and redistribution, with licensing tools for software publishers. It works with native EXE, DLL, and SCR files as well as .NET Framework 4.x executables, and supports Windows XP through Windows 11. Developers can virtualize selected native code into bytecode for a virtual CPU, encrypt code and data, and use integrity checks and measures against disassembly and debugging. The licensing systems use RSA or elliptic-curve cryptography and can set expiration dates, lock licenses to hardware, encrypt code according to license status, and blacklist keys. Evaluation periods can end on a fixed date, after a set number of days or executions, or following specified application actions. The package includes an SDK with examples for C/C++, Delphi, Rust, C#, Visual Basic, PureBasic, and other languages, plus a license-key generation library supplied as a Windows DLL and Linux CGI. Network Licensing runs as a locally installed service to distribute floating-license pools within a corporate network. Obsidium is paid software with a free trial. License options include Company and Personal; Lite is limited to 32-bit applications and personal licensing. Both license types include email or forum technical support and free updates for 12 months.

Who it suits

Obsidium suits software companies publishing Windows applications that need to protect binaries and provide time- or feature-limited evaluations. Its SDK, licensing options, and network licensing also fit developers with custom licensing or corporate floating-license needs.
