android, desktop: blur media thumbnails in reply quotes and the chat list (#7639) "Blur media" hid images and videos in a chat but showed the same media sharp as the thumbnail of a quoted message and as the last message's image, video or link preview in the chat list. Small views are now blurred with the same reveal as chat media. They are resampled relative to the width they are drawn at, so a thumbnail is blurred as much on screen as media in a chat, and drawn as the centre crop the thumbnail shows. In-chat media keeps the same blur. Blurring the chat list also needs: each last message gets its own blur state, loaded chat-list videos use it and hide their full-screen play button while blurred, a right-click on a thumbnail no longer leaves it revealed on desktop, and leaving a chat mid-scroll no longer undoes reveals in the list on Android.

android, desktop: make media blur much lighter on CPU (#7483) * ui: blur media by resampling the preview, not a per-frame effect Modifier.blur put a BlurEffect on a display-sized graphics layer, so the Gaussian was re-evaluated on every frame the media was drawn. It also requires RenderEffect, which Android applies only from API 31, so below Android 12 media was drawn unblurred while the setting read as on. A blur and a downscale discard the same thing - detail finer than their radius - so the preview is now resampled to about one pixel per radius and stretched back. That runs once when the item composes, needs no RenderEffect, and removes the detail irreversibly rather than convolving it. The first resampling step bounds both sides, so no image, however shaped, can produce a large intermediate. While the blur hides the media the file is also left unread, so an image scrolled past is no longer read, decoded at its full size and kept in the image cache only to be hidden again. blurHidesMedia() is the single definition that both the drawing and the loading decision use, so they cannot disagree about whether the media is on screen. * plans: blur media by resampling the preview * ui: shorten comments in media blur * ui: smooth the media blur and match its strength to the old one Stretching the resampled preview straight to the screen showed its pixel grid. Double it back up until its longest side is at least half the reference width before drawing, so the last stretch is short and the tents compose into a bell. The reference width moves from 360 to 400: fitted against Gaussians, 360 blurred 5-75% more than Modifier.blur did, 400 is within 10% at every setting. (cherry picked from commit c0344a9a61d8f9622283dd2b0c8610ffede95a99)

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 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.
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, 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.
