@BriarApp For when a version for Windows or iOS

Briar Desktop 0.5.0-beta released - macOS support, private groups and Briar Mailbox briarproject.org/news/2023-bria…

Today, we officially released Briar Mailbox to improve connectivity between peers: briarproject.org/news/2023-bria…

@STP_KITT No, see code.briarproject.org/briar/briar-ma…

@BriarApp Can one mailbox be used by more than one Briar user account?

@digest_anon1 @mbrochh @maxtannahill You don't need a mailbox. That's an optional feature. Imagine the extreme case of two users that are never online at the same time (maybe for timezone reasons).

@DeiPlus Without the mailbox, both peers need to be online at the same time (have a connection) to exchange messages. With the mailbox, only the mailbox needs to be online. Messages will be delivered when one peer comes online.

@BriarApp A question arises to me: Basically that's not what Briar was doing? When you connect, the messages enter and are stored locally.

@mbrochh @maxtannahill While you are offline, contacts leave messages for you on your (or their) mailbox. You are hosting that mailbox, typically on an old Android phone: briarproject.org/download-briar…

@rid0uoff Please see the end of this page: briarproject.org/download-briar…

@BriarApp Will this feature be possible to host in a computer (server) instead of Android device ? In a docker container for example

.@BriarApp definitely deserves more attention from the research community. They are trying to do something quite challenging with secure ad hoc messaging.

A nice open research challenge is to try to prove the security of Briar’s protocol stack. Tricky given the complex layering involved.

Overall, we are happy to report that Briar had done a pretty good job in their crypto design. Disclosure was very smooth.

Congrats to Yuanming Song on finding these vulnerabilities during his semester project making a “deep dive” on Briar’s cryptographic protocols.

@ETH_en These are the researchers that also did MEGA: Malleable Encryption Goes Awry mega-awry.io Breaking Threema breakingthe3ma.app Breaking Bridgefy eikendev.github.io/breaking-bridg… The analysis of Briar didn't get its own homepage.

The report of the security researchers at @ETH_en is available here: ethz.ch/content/dam/et… (PDF) "These claims, if true, would mean that Briar offers a higher level of security than almost all existing messaging applications."

Three security issues found and fixed briarproject.org/news/2023-thre…

Found a cool way to repurpose some old tech, side loaded an old version of @BriarApp to run on my ancient q10 to make it a secure mobile messenger and it works pretty well paired with a battery powered travel router it's a neat little package #comms #secure #mobile #offgrid
