The Briar Project released version 1.2 of its Android app today.
The Briar Project released version 1.2 of its Android app today.
This release allows users to add each other securely without needing to meet in person.
This release allows users to add each other securely by exchanging links.
Previously users needed to meet in person or ask a mutual contact to introduce them.
With earlier versions of the app,
people could already add someone remotely by getting an introduction from a mutual trusted contact.
However, most people found this inconvenient
and requested an easier and more direct way of adding contacts.
The developers hope that Briar will be useful for an even larger set of users now.
The new version provides a special link for each user
that two users need to exchange (over other channels) in order to add each other.
Most messenger apps find your contacts by uploading your phone's contact list to a server.
Since Briar is protecting metadata and contact relationships,
Since Briar is protecting metadata and contact relationships,
it does not use the phone's address book to harvest contacts.
it instead uses the Tor network

without revealing your contact list to anyone.
The onion service is only used to add this one single contact
by exchanging cryptographic keys and other information.
It will be discarded once the contact was added.

Instead of adding the correct contact, the attacker is added thus defeating end-to-end encryption.
