CAFEGOPHER

A Go library for interacting with serialized Java objects

Introduction

This library grew out of a need to parse serialized Java in JCE keystores. (As far as I can tell, the serialized Java objects in these keystores do not include a length prefix, so there is no way skip over them without parsing them.) For now, this library is limited to prasing/unmarshalling. Maybe someday I'll add serialization support as well, but that is not on the critical path for the more interesting work I'm doing.

The name of the library is a reference to 0xCAFEBABE, the "magic bytes" of Java class files.
