@ullarah@txt.quisquiliae.com Didn’t we talk about at some point a way to set the maximum height of te panels with some UX way to read the rest? 🤔 Is that still on the cards or a bad ideas? 🤔

I would HIGHLY recommend reading up on the keybase architecture. They designed device key system for real time chat that is e2e secure. https://book.keybase.io/security

A property of ec keys is deriving new keys that can be determined to be “on curve.” bitcoin has some BIPs that derive single use keys for every transaction connected to a wallet. And be derived as either public or private chains. https://qvault.io/security/bip-32-watch-only-wallets/

@tamer@twtxt.net We’re not trying to compete with anything… If you’ve read About Yarn.social – In a nutshell I want to create an open, transparent social platform that respect’s folks privacy and freedoms. It must also be easy to use and down-to-earth where human interactions actually matter. None of this rubbish of manipulating what you see, driving up engagement numbers to serve your advertisers and all that garbage

Autocrypt - Wikipedia

Just reading in-depth and trying to understand the security model of Delta.Chat a bit more… There’s a few things that really concern me about how Delta.Chat which relies on Autocrypt work:

• There is no Perfect Forward Secrecy
  
• No verification of keys
  
  • Is therefore susceptible to Man-in-the-Middle attacks
    
• Metadata is a BIG problem with Delta.Chat:
  
  • The To and From and Date are trackable by your Mail provider (amongst many other headers)
