У меня есть следующие данные ProtoBuf в кодировке Base64 в качестве входных данных из Java приложения в файле, и я хочу прочитать их, используя Python:

message = "CTwwFl8AAAAAEAAY + LKJASAAKAEyvwYvY2dpLWJpbi90cmFjVud2 / /////// 8Bes0BTW96aWxsYS81LjAgKExpbnV4OyBBbmRyb2lkIDEwOyBTTS1BMzA1R1QgQnVpbGQvUVAxQS4xOTA3MTEuMDIwOyB3dikgQXBwbGVXZWJLaXQvNTM3LjM2IChLSFRNTCwgbGlrZSBHZWNrbykgVmVyc2lvbi80LjAgQ2hyb21lLzgzLjAuNDEwMy4xMDYgTW9iaWxlIFNhZmFyaS81MzcuMzYgKE1vYmlsZTsgYWZtYS1zZGstYS12MjAyMDA2OTk5LjIwMTAwNDAwMC4xKYABAYgB4eathAKQAQKaAQCiATUyMjU5NzgxM2I0OTZlYjA5YTI3ZTA3ZmE2NDg1YjRmY2JjODJiZWQzNzQwMWZiNjUzNTc4N6oBIDQyYTBmZTY1Y2FlNTExZWE5N2Q1MGUyNjZiNjAyNmVksAEBuAH92Nj4BcABAsgBANABAdgBAeABjIoD6AHnePABgTz4AYLSB4ACmvoBiAIBkAL /////////// 8BmAL /////////// 8BoAL /////////// 8BqAIysALAArgCAcACCMgCAdACAtkCb / CFyVTBsD / gAgHoAgDwAgD4ApxOgQMAAAAA16OwP6gDALADALoDkwEoKDE5OTg5NDgmMTk5ODk0OSl8KDE5OTg5NTAmMTk5ODk1MSl8KDE5OTg5NTImMTk5ODk1Myl8KDE5OTg5NTQmMTk5ODk1NSl8KDE5OTg5NTYmMTk5ODk1Nyl 8KDE5OTg5NTgmMTk5ODk1OSl8KDE5OTg5NjAmMTk5ODk2MSkpJigxOTk4OTYyKSYoMTk5ODk2MynCAwkIoJF8FQAAgL / IAwDQAwHYA /////////////////////////////////////////////////////////////////////////////////////////////////////////// //// wGABAaIBP /////////// wGQBACYBACgBACoBAK4BJf2e7gEu4l8wQQAAAAAAAAAAMkEb / CFyVTBsD / SBAkKABIBMBoAIgDYBADgBADwBAP4BASABUGIBQGQBQCYBQOiBQUNAACAP6gFnAOwBawGuAUAwAUAygUCMTDQBQLaBQc0MTJ4ODEy4gUDQ1BN6QUAAAAAAADwP / EFAAAAANejsD / 5BV0471w4oww / gQYpXI / C9SisP4oGAJIGAJoGAKEGgcGrf3Gzsj + oBgSyBgC5BgAAAAAAAAAAyAZi2Ab /////////// 8B4Ab /////// //// 8B6AYA8Ab /////////// 8B + Ab /////////// 8BgAf /////////// 8BiAcBkAcAmAcAogcAqAcBsAcDugcMNDUuMTc3LjE5NC4wwAcAyAf /////// //// 8B0Af /////////// 8B2Af /////////// 8B4gcA6gcCLTE = "

Я пытался декодировать и читать сообщение, но получал непечатаемые данные. Как я могу прочитать данные? Я новичок в ProtoBuf. Кто-нибудь, пожалуйста, проведите меня сюда.
