Krakatau

Krakatau 提供了 Java 字节码的汇编器和反汇编器，使你可以将二进制类文件转换为人类可读的文本格式，进行修改，然后转换回类文件，即使是混淆代码也能处理。你也可以通过手动编写字节码从头创建自己的类文件，并检查和比较 Java 二进制文件的底层细节。与 javap 不同，Krakatau 反汇编器甚至可以处理高度混淆的代码，并且反汇编后的输出可以重新汇编成类文件。 Krakatau 还提供了一个反编译器，用于将 Java 二进制文件转换为可读的源代码。与其他反编译器不同，Krakatau 反编译器专门设计用于处理混淆代码，并能轻松应对其他反编译器无法处理的技巧。然而，Krakata...
