Signal chat protection against quantum computers

I'd just be happy if there was a way to restore my messages from Android to iOS (or vice-versa). I'm going to lose my messages from the past 4 years because of this. And it's been an open request with the devs for 5 years now.
- Yeah, they seem to put a lot of energy into esoteric features, when the app is in serious need of some quality of life improvements. I donate a tiny monthly sum to the project and honestly feel conflicted about how effectively it's being used.
  
  Or maybe chat history just isn't that important overall. I can do backups just fine on android but have only used that once. I wouldn't be too concerned if I lost all of my chats, as I've already read them.
  The core security and privacy features are what's most important. I'd prefer they keep those as the top priority.
  
  Like the checking for messages notification on Android, I use notification reminder app to remind me of missed messages (ring every 5 minutes) and sometimes randomly in the middle of the night Signal creates a notification that says "checking for messages" and it stays there for a while getting my notification remjnder to think there is an unread message and ringing in the middle of the night. I can't turn off notifications I might need to be waken up for important stuff.
  
  One stupid thing I've come across...you can either choose per contact or overall what the chat bubble color is, but when I do so, MY chat bubbles are colored and everyone else's are grey. That seems backwards to me. If I want to do "Pink is this person, blue is that person, green is that person" it ends up going "wait whose end of the conversation is this again?"
  Does someone have a patent they're trying not to infringe?
- Plus this refusal to allowing Chats to Whatsapp and Facebook Messenger now that EU forced meta to open this up...
  I know the devs are not happy about meta tracking everything on their end but why can't this be a users choice to enable communication with no-signal servers as well?
  
  I haven't seen their refusal but I imagine it's for the same reason they ditched SMS.
  They don't want their users confused about what is and is not a secure message.
  
  Did Signal devs openly refuse making use of that? Honestly I think it's understandable.
  They are marketing the app as a very-very secure messaging app, but all the security with no exception would go out of the window if you were to send or receive a message from messenger.
  And they are also making it very-very easy, because - as bad as it sounds - a lot of people don't understand what is encryption, what are platforms, and they don't even care to get to know about it, and because of that, these users would have no idea that their chats with messenger users is not encrypted.
  
  That law is for chat apps that have a user base over like 40M. Is Signal even that large yet?
- I synchronized with my laptop to save a copy of all my messages. Would this be a viable solution for you?
- Although I have no use for storing chat history, SimpleX Chat has an (encrypted) database export feature that should, as far as I know, let you keep your chat history forever so long as you back it up.

And if I wasn't sold on Signal I am now.

Hey wow, the art (the Bloch sphere) is actually relevant to the subject matter of the article.
Yay photo editor!

I was under the impression that Signal could handle SMS and RCS and be a replacement for a phones messaging app. Am I misguided or is Signal more of an WhatsApp alternative that I can only communicate with people already on Signal
- The latter is true unfortunately. Because of understandable security reasons they gave up the SMS integration about a year ago since it's unencrypted and not a good fit to the security standards of signal.
  Until there is some form of open interconnection between messaging apps there will be no end to WhatsApp.
  Don't get me wrong, signal is a great alternative, but it does not achieve more then it's core value of security, and this will never be enough.
  
  Afaik Signal will never interface with platforms such as WhatsApp because it would mean they'd have to lower their security standards.
  
  Thanks for taking the time to educate me! It’s appreciated

Quantum computers are like fusion, ready in a decade.
- Technically ready and available now, just not ready to compete with classical computers.
  Which, sadly, is a step above what fusion has achieved so far.

People who think this development was a waste of time are using the wrong app

- Just realized how much potential there is for transparent background memes on Lemmy... absolutely beautiful
