Overview

A message serializer that serializes Messages with JSON.

The generated structure is pretty simple:

{
  p: <payload>,
  h: {
    header1: value1,
    header2: value2,
    #...
  }
}

Both the payload and the header values are encoded with Base64 to prevent JSON parsing errors and encoding issues when storing the resulting serialized data.
