Signal has made encrypted on-device backups available to all users of its iOS app. Users can update to version 8.30, then enable the feature in Settings > Backups and set up a Recovery Key, which Signal warns must be stored securely and never shared. The move lets iPhone and iPad users preserve their message history locally without handing data to cloud services, a change privacy-focused users have long requested.
- 2Developer builds working 3D Enigma machine simulatorβShow HN: A working 3D model of an Enigma machine
A new interactive website lets users operate a fully functional 3D model of the Enigma machine, the German cipher device used during World War II. Visitors can rotate the model, press keys, and watch the rotors and plugboard simulate real encryption. The project is drawing interest for combining historical computing history with hands-on interactive design.
- 3App maker touts instant one-click data exportβData portability usually means filing a request and waiting weeks for a zip file. In my app itβs a button: Settings, Exp
A developer is promoting an app that lets users export all their data instantly via a single button in the settings menu, delivering everything as JSON or CSV, or as an encrypted copy protected by a user-chosen passphrase. The developer contrasts this with the usual data portability process, which typically involves filing a request and waiting weeks for a download, and notes that users can export without closing their account.
- 4Securing home network services with HTTPS explainedβheise+ | HTTPS im Heimnetz: So sichern Sie lokale Dienste ab Selbst gehostete Dienste lassen sich dank DNS-01-Challenge
German tech outlet heise has published a guide explaining how to secure self-hosted services in a home network with HTTPS. It describes how the DNS-01 challenge lets users obtain Let's Encrypt certificates for local services without exposing them to the public internet. The piece is aimed at home server operators who want encrypted connections for internal tools.
- 5NASA's APOD site serves a certificate dated in the futureβ`openssl s_client -4 -connect apod.nasa.gov:443` Nice cert you got there, NASA :-) ``` Certificate chain 0 s:CN=go-vip.c
A system administrator ran a TLS check against apod.nasa.gov and found the site's certificate chain shows a validity window starting in late 2026, issued via Let's Encrypt. The odd future-dated dates have drawn amused attention from tech observers, who note that such entries usually point to certificate misconfiguration or overlapping issuer logs rather than anything nefarious. NASA has not commented on the quirk.
