scripts: match AGP zip alignment in android reproduce build (#7196) Release APKs are packaged by AGP (:android:assembleRelease), which zero-pads ZIP alignment. verify_apk re-aligned the rebuilt APK with repro-apk's --pad-like-apksigner (the 0xd935 extra-field scheme of standalone apksigner >= 35.0.0-rc1), so apksigcopier aborted with "APK Signing Block offset < central directory offset". Drop the flag so the padding matches AGP's output; the rebuilt APK then reproduces the published one byte-for-byte.

desktop: fix in-app updater deleting the download before "Open file location" (#7104) * desktop: fix updater deleting the download before "Open file location" The in-app updater downloads to a temp UUID file via createTmpFileAndDelete, then relies on `file.renameTo(newFile)` to move the bytes to the asset name so they survive that helper's `finally { tmpFile.delete() }`. The rename's return value was ignored: if it failed, the bytes stayed at the UUID path and the finally block deleted the only copy, so the "Download completed" dialog appeared but "Open file location" opened an empty /tmp/simplex. Use Files.move with REPLACE_EXISTING instead. It performs the same in-place rename when possible (verified: inode preserved, no copy), falls back to copy+delete when an atomic rename isn't possible, and throws on genuine failure - which the existing outer catch handles - instead of silently losing the file. * docs: plan for updater open-file-location fix * docs: plan - note Whonix compatibility (updater previously failed there)

ios: open SimpleX links in chat messages via in-app connect flow (#7101) * ios: open SimpleX links in chat messages via in-app connect flow Tapping an inline SimpleX connection link in message text was dispatched through UIApplication.shared.open. iOS drops an open() of a URL owned by the same app while it is in the foreground (the simplex: scheme and the simplex.chat universal links both belong to this app), so the tap was ignored and never reached the connection flow. Web links (Safari) and mailto:/tel: (other apps) were unaffected, which is why only SimpleX links appeared dead. Route SimpleX links to ChatModel.appOpenUrl instead - the same sink onOpenURL feeds, leading to connectViaUrl/planAndConnect. This matches the connection-link card and the multiplatform clients, which connect in-process rather than via an OS round-trip. Also fixes the same problem for the "Send questions and ideas" and "connect to SimpleX Chat developers" buttons, which open simplexTeamURL (a simplex: link) the same broken way. * docs: plan - justify iOS in-app dispatch for SimpleX links in messages Root cause and justification for opening inline SimpleX links via the in-app connect flow instead of UIApplication.shared.open (undefined re-entry of the same foreground app for a self-owned simplex: URL).

SimpleX Chat: secure messenger

SimpleX - the first messaging network without user identifiers of any kind (not even random numbers) - 100% private by design! Security assessments by Trail of Bits: 2022: https://simplex.chat/blog/20221108-simplex-chat-v4.2-security-audit-new-website.html 2024: https://simplex.chat/blog/20241014-simplex-network-v6-1-security-review-better-calls-user-experience.html SimpleX Chat features: - quantum resistant end-to-end encrypted messages, with editing, replies and deletion. - disappearing messages with opt-out per contact/group. - message reactions. - delivery receipts, with opt-out per contact or group. - multiple chat profiles, with hidden profiles. - app access and self-destruct passcodes. - incognito mode - unique to SimpleX Chat. - end-to-end encrypted images and files. - voice messages up to 5 minutes – also end-to-end encrypted. - "live" messages – they update for all recipients as you type them, every few seconds - unique to SimpleX Chat. - connect via one-time invitation links or via long-term public addresses. - secret chat groups - only group members know the group exists and who is the member. - end-to-end encrypted audio and video calls. - connection security code verification, for contacts and group members – to protect from man-in-the-middle attacks (e.g. invitation link substitution). - end-to-end encrypted push notifications (they contain only encrypted meta-data, not the actual content). - encrypted portable chat database - you can transfer your chat contacts and history to another device. - all local files and media are encrypted by default. - animated images and "stickers" (e.g., from GIF and PNG files and from 3rd party keyboards). SimpleX Chat advantages: - privacy of your identity, profile, contacts and metadata: unlike any other existing messaging platform, SimpleX uses no phone numbers or any other identifiers assigned to the users - not even random numbers. This protects the privacy of who you are communicating with, hiding it from SimpleX platform servers and from any observers. - complete protection against spam and abuse: as you have no identifier on SimpleX platform, you cannot be contacted unless you share a one-time invitation link or an optional temporary user address. - full ownership, control and security of your data: SimpleX stores all user data on client devices, the messages are only held temporarily on SimpleX relay servers until they are received. - decentralized proxied peer-to-peer network: you can use SimpleX Chat via your own relay servers and still communicate with people using pre-configured or any other SimpleX relay servers. - fully open-source code. You can connect to anybody you know via link or scan QR code (in the video call or in person) and start sending messages instantly - no emails, phone numbers or passwords needed. Your profile and contacts are only stored in the app on your device - relay servers do not have access to this information. All messages are end-to-end encrypted using open-source quantum resistant double-ratchet protocol; the messages are delivered via relay servers using open-source SimpleX Messaging Protocol. Please send us any questions via the app (connect to the team via the app settings!), email [email protected] or submit issues on GitHub (https://github.com/simplex-chat/simplex-chat/issues) Ream more about SimpleX Chat at https://simplex.chat Get source code in our GitHub repo: https://github.com/simplex-chat/simplex-chat Follow us on X/Twitter (@SimpleXChat), Reddit (r/SimpleXChat/) and Mastodon (https://mastodon.social/@simplex) for the latest updates.

More Encrypted Messaging

Matrix
matrix.org

Matrix is a decentralized open network for secure communications, with E2E encryption with Olm and Megolm. Along with the Element client, it supports VOIP + video calling and IM + group chats. Note that homeservers can log IP addresses and metadata, and unrelayed 1:1 calls may reveal your IP to the other party.

Signal
signal.org

Probably one of the most popular, secure private messaging apps that combines strong encryption (see Signal Protocol) with a simple UI and plenty of features. It's widely used across the world, and easy-to-use, functioning similar to WhatsApp - with instant messaging, read-receipts, support for media attachments and allows for high-quality voice and video calls. It's cross-platform, open-source and totally free. Signal is recommended by Edward Snowden, and is a perfect solution for most users.

XMPP
xmpp.org

XMPP, also known as Jabber, is an open standard for decentralized messaging that has been widely used for decades. It has actually been the basis upon which WhatsApp, Facebook's Chat and Google's Talk were built, but these companies (eventually) chose to remove the interoperability with other servers. Prominent XMPP clients support OMEMO end-to-end encryption, which is based on the Double Ratchet Algorithm that is used in Signal. For more hands-on information and to register an account you can visit JoinJabber.
