For ipod instal KeyKey2/8/2024 The Maps application on both macOS and iOS use many protobufs to store location data. I will parse out some protobufs from different applications to give you an idea of what is stored in them - Maps, Locations, Health, and Notes. To parse a given buffer I will use the following command: protoc -decode_raw < On a Mac, I would do a ‘brew install protobuf’ to get protoc installed. proto file you can use this as well, but I have yet to give that a go. To parse these protobufs, I use protoc from Google to get a raw output. Unfortunately, we likely do not have this file as it is most likely server-side or inaccessible therefore we need to reverse engineer the contents and meaning of the items stored in this blob. The kicker with protobufs is that there is an accompanying *.proto file that contains the definition to what is contained in these buffers. ![]() Some are fairly straight forward, others are less so. In this article I’ll introduce you to some of the Apple-specific protobufs that I’ve come across. It took me a long time to also notice that they were being stored on Apple devices! Native applications, 3rdparty applications, they are used EVERYWHERE! A great example was found by my friend Phill Moore in the iOS Spotify application to keep track of items listened to. I started noticing them more and more on Android devices, not just in the network traffic but also storing data on disk as well. ![]() Since I was looking at an Android device, a protobuf made perfect sense. It is a super-efficient way of storing and transferring data. It is a “language-neutral, platform-neutral extensible mechanism for serializing structured data” created by Google. Ok, so what the heck is a protobuf? It actually stands for Protocol Buffer, but everyone calls them protobufs.
