Col-E/Recaf
Recaf
Recaf 是一套专门用于汇编、编辑、去混淆、反编译和检测 Java 字节码及运行时进程的工具。它提供了一个协调环境，用于修改已编译的 Java 类文件并分析 Java 应用的行为。
该项目的独特之处在于一个多级抽象层，允许跨不同格式进行编辑，以及一个通过多个可配置反编译引擎路由字节码的可插拔框架。它包括一个嵌入式脚本引擎和插件架构，以自动化重复任务并扩展系统行为。
该工具集涵盖了几个高级能力领域，包括用于搜索应用内容和模拟方法执行状态的静态分析。它还支持用于附加到实时进程的运行时检测，以及用于移除混淆和修复类文件的自动化字节码转换。
通过命令行界面支持无头执行，以便将工作流集成到外部构建流水线中。
