Show HN: Share It, Anonymously with Self Destruct Messages
Taking advantage of this post to ask about this -- can anyone explain to me why Signal can&#x27;t be implemented as a completely offline-first&#x2F;PWA web-app.<p>If we throw away the more advanced requirements of perfect forward secrecy, non repudiation, ratcheting for groups, non repudiation, why is it a bad idea to get 80% of the way there with basic offline-first&#x2F;WPA (+&#x2F;- secure enclave, WebAuthN, whatever else) messages that are stored on peoples&#x27; devices, encrypted before being sent out etc.<p>Excalidraw is an excellent app that&#x27;s actually already written about this[0], so we know it&#x27;s possible in some form. There&#x27;s exciting p2p technology in the browser (ipfs, gun, etc). To reach all the platforms you could use Electron and in the future Tauri (which purports to be less of a drain on system resources), etc.<p>What am I not seeing about why this fundamentally can&#x27;t be done and I can enjoy relatively simple encrypted chat without worrying about installing too many things, in a throw-away shell somewhat similar to pastenow.me? Is it just that no one has built it? surely not<p>NOTE -- I don&#x27;t mind too much about not having to be online at the same time to share information with someone else, I don&#x27;t think it&#x27;s too hard these days to coordinate a time to share initial contact information&#x2F;status<p>[EDIT] correct &quot;offline&quot; to &quot;offline-first&#x2F;PWA&quot; since it was leading to confusion, didn&#x27;t include the &quot;-first&quot; enough places, clearly.
