Piped is a privacy-respecting open-source alternative frontend to YouTube.
I’m open-source, check me out at GitHub.
essentially, yes. There are two levels of encryption keys and they “ratchet” along (change). Only the lower level is used to encrypt the text so it’s much harder to figure out the other one.
@sexy_peach Thank you very much! Just now wondering, handle WA this differently? Since Ig we all know this message which appears when the “keys” ig, changed
I don’t know if I fully understand you here.
To my understanding whatsapp does it like this too. The key changing must be the high level key, since the message means that it’s an unknown key (thus not yet trusted). From new install or new device.
@sexy_peach Okay, got it, ig.
