Honest question for those in the know: If I wanted to run my own personal “analysis” to verify the security of Signal, where would I start? Is it even possible? Just curious if there was a way to “know” rather than “trust”.

Learn cryptography to a high level then read the source code?

I never realized signal code was available open source... so in theory one could “build” then load the software via developer tools (assuming you have an iOS dev account).

Are there any “certs”/keys you would need to talk to your contacts?
