VMProtect 是新一代的软件保护系统,将保护后的代码放到虚拟机中运行,这将使分析反编译后的代码和破解变得极为困难。使用 MAP 文件或内建的反编译引擎,您可以快速选择需要保护的代码。 与传统保护方式的比较: 传统的保护软件都有一个共同的弱点,即他们都不修改源代码。保护方式仅仅是通过“信封”原理将软件主体封装起来,然后通过一个装载器解压缩保护的软件主体,解压后的软件在内存中很容易被转储并被非法修改。破解者拥有一系列反编译工具可以破坏这种保护,网络上也有许多文章阐述如何脱壳常规的保护软件。 VMProtect 是新一代的软件保护系统,不像市场上其它常见的保护软件,VMProtect 可以修改软件产品的源代码,转换部分代码为在虚拟机上运行的字节码(bytecode)。您可以将虚拟机想象成为带有不同于 Intel 8086 处理器系统指令的虚拟处理器。例如,虚拟机没有比较两个操作数的指令,也没有条件跳转和无条件跳转指令等等。这样一来,破解者就需要开发一整套的解析引擎来分析和反编译字节码,以现有的解密理论,破解者想要还原出源代码几乎是不可能的。
