sito VS Keychain-Dumper

As of recent I've been weirdly fascinated with codecs, serialization protocols, file formats, and the like. It scratches that low-level hacking itch (I spent most of my professional programming in web dev space) without as much commitment to electronics (used to be super big into arduino but I find that's harder to pick up and put down).

I've started hacking on my own container format (yeah, I know, xkcd927), after finding it super frustrating to embed arbitrary time-synched data streams into mp4/matroska/ogg/etc. Also it bugs me how crusty, complicated, and arcane mp4 is, and at the same time, mastroska and ogg are weirdly opaque given how they are supposed to be open standards.

If anyone is curious, here's my container format I've been developing: https://github.com/xkortex/sito

Re keychain, you're probably aware of it, but https://github.com/ptoomey3/Keychain-Dumper/ is very thorough in extracting keychain data (including data that one would expect to no longer be in there).

I have also tried Keychain-Dumper, but when I run this via SSH I get an error saying "No Password Keychain items found. You should Unlock your device" (my device has a 4 digit passcode that has been entered before running the dumper). I can see the Keychain-2.db and Keychain-ota-backup.plist that seem to contain the info I need, but its all heavily encrypted.
