Obsidium vs PELock

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.

PELock protects compiled 32-bit Windows applications against cracking, tampering, and reverse engineering, while providing software licensing tools. It protects Portable Executable formats including EXE, SCR, DLL, OCX, CPL, BPL, DPL, ACM, and AX. Anti-debugging methods detect cracking tools and block their actions. The license key manager handles users and keys, generates and verifies RSA-2048 keys, and can block illegally shared keys. Trials can be limited by days, executions, an expiration date, or minutes of use. A virtual DLL binder combines an application and libraries into one EXE, loading those libraries in memory without writing them to disk. SDK examples cover C/C++, Delphi, Lazarus, FreePascal, PureBasic, PowerBASIC, D, and Assembler. Plugins can add compression, detection, licensing checks, and loader functions. The maker lists Windows support from Windows 95 through Windows 10 and Server 2003 through 2012, with 32- and 64-bit support. Pricing starts at 59 one-time; listed licenses cost 159.00 USD or $299, paid once.
