About

pbtk (Protobuf toolkit) is a full-fledged set of scripts, accessible through an unified GUI, that provides two main features: - Extracting Protobuf structures from programs, converting them back into readable .protos, supporting various implementations: All the main Java runtimes (base, Lite, Nano, Micro, J2ME), with full Proguard support, Binaries containing embedded reflection metadata (typically C++, sometimes Java and most other bindings), Web applications using the JsProtoUrl runtime. - Editing, replaying and fuzzing data sent to Protobuf network endpoints, through a handy graphical interface that allows you to edit live the fields for a Protobuf message and view the result.
