pbtk (Protobuf toolkit) is a Python-based set of scripts with a unified GUI for extracting Protobuf data structures from programs (Java runtimes, binaries with reflection metadata, web apps) back into readable .proto files. It also lets users edit, replay, and fuzz data sent to Protobuf network endpoints through a graphical field editor.
Use cases
- extract .proto definitions from an Android APK
- recover protobuf schemas from a compiled binary
- fuzz a protobuf-based network endpoint
- edit and replay protobuf messages sent to a server
- reverse engineer an app's network protocol
- decompile protobuf structures with Proguard support
When to choose
- you need to reverse engineer Protobuf structures from Java/Android apps or native binaries
- you want a GUI to live-edit and fuzz Protobuf messages against endpoints
- you need to recover .proto files from apps lacking source
When to avoid
- you need to extract schemas from modern web apps using JsProtoUrl (needs update)
- you work with very recent Java protobuf obfuscation in new APKs
- you need a maintained, actively developed tool (project is stable but ageing)
