VMProtect是新一代软件保护实用程序。VMProtect支持德尔菲、Borland C Builder、Visual C/C++、Visual Basic(本机)、Virtual Pascal和XCode编译器。
同时,VMProtect有一个内置的反汇编程序,可以与Windows和Mac OS X可执行文件一起使用,并且还可以链接编译器创建的MAP文件,以快速选择要保护的代码片段。
为了轻松实现应用程序保护任务的自动化,VMProtect实现了内置脚本语言。VMProtect完全支持Windows系列的32/64位操作系统(从Windows 2000开始)和Mac OSX(从版本10.6开始)。重要的是,无论目标平台如何,VMProtect都支持所有范围的可执行文件,即Windows版本可以处理Mac OS X版本的文件,反之亦然。

一个处理Mach-O文件的课程:
class MacFile { public: string name(); // returns the name of the file string format(); // returns the name of the "Mach-O" format uint64 size(); // returns the size of the file int count(); // returns the number of architectures in the list MacArchitecture item(int index); // returns an architecture with the given index uint64 seek(uint64 offset); // sets the file position uint64 tell(); // returns the file position int write(string buffer); // writes a buffer to the file };
一个使用Mach-O架构的课程:
class MacArchitecture { public: string name(); // returns the name of the architecture MacFile file(); // returns the parent file uint64 entryPoint(); // returns the starting address OperandSize cpuAddressSize(); // returns bit count of the architecture uint64 size(); // returns the size of the architecture MacSegments segments(); // returns the list of segments MacSections sections(); // returns the list of sections MacCommands commands(); // returns the list of load commands MacSymbols symbols(); // returns the list of symbols MacImports imports(); // returns the list of imported libraries MacExports exports(); // returns the list of exported functions MacFixups fixups(); // returns the list of fixups (relocations) MapFunctions mapFunctions(); // returns the list of functions available for protection IntelFunctions functions(); // returns the list of protected functions bool addressSeek(uint64 address); // sets the file position uint64 seek(uint64 offset); // sets the file position uint64 tell(); // returns the file position int write(string buffer); // writes a buffer to the file };
一个用于处理Mach-O结构段列表的类:
class MacSegments { public: MacSegment item(int index); // returns a segment with the given index int count(); // returns the number of segments in the list MacSegment itemByAddress(); // returns a segment at the given address };
