New code suggests Twitter is reviving its work on encrypted DMs • TechCrunch

Below Elon Musk, Twitter could also be reviving a mission that might deliver end-to-end encryption to its Direct Messaging system. Work seems to have resumed on the characteristic within the newest model of the Android app, in line with impartial researcher Jane Manchun Wong, who noticed the modifications to Twitter’s code Whereas Musk himself recently expressed interest in making Twitter DMs safer, Twitter itself had deserted its earlier efforts on this house after prototyping an encrypted “secret conversations” characteristic again in 2018.

Had the encrypted DM’s characteristic launched, it will have allowed Twitter to raised problem different safe messaging platforms like Sign or WhatsApp. However work on the mission stopped and Twitter by no means publicly defined why — nor had it commented on the prototype Wong had additionally discovered being developed within the app years in the past.

Now, Wong says she’s seen work on encrypted DM’s resume, tweeting out a screenshot of Twitter’s code which references encryption keys and their use in end-to-end encrypted conversations. One other screenshot reveals a “Dialog key,” which the app explains is a quantity generated by the consumer’s encryption keys from the dialog. “If it matches the quantity within the recipient’s cellphone, end-to-end encryption is assured,” the message reads.

In response to Wong’s tweets, Musk replied with a winking face emoji — an obvious affirmation, or at the very least what stands in for one today, provided that Twitter laid off its communications employees and not responds to reporters’ requests for remark.

Not like the opposite initiatives Musk’s Twitter has within the works, like a relaunch of the Twitter Blue subscription now due out later this month, end-to-end encryption is one thing that can’t– and shouldn’t — be rushed out the gate.

Meta, for instance, took years to completely roll out end-to-end encryption (E2EE) in Messenger, after having first examined the options in 2016. It wasn’t till this summer time that Meta introduced it will lastly increase its E2EE check to particular person Messenger chats. The corporate defined the delay to launch was, partially, as a result of want to deal with considerations from little one security advocates who had warned the modifications may defend abusers from detection. Meta additionally supposed to make use of A.I. and machine studying to scan non-encrypted components of its platform, like consumer profiles and pictures, for different alerts that might point out malicious exercise. Plus, it wanted to make sure that its abuse reporting options would proceed to work in an E2EE surroundings.

In brief, past the technical work required to introduce E2EE itself, there are complicating components that ought to be considered. If Musk broadcasts encrypted DMs in a compressed timeframe, it will elevate considerations about how safe and well-built the characteristic could also be.

Plus, with Twitter’s 50% workforce discount and the departure of key employees — together with chief info safety officer Lea Kissner, who would perceive the cryptological challenges of such a mission — it’s unclear if the remaining workforce has the experience to deal with such a posh characteristic within the first place.

Musk, nonetheless, appears to imagine encryption is the precise path for Twitter’s DM product, having just lately tweeted “the aim of Twitter DMs is to superset Sign.” And, in response to a consumer’s query about whether or not Twitter would merge with telecommunication or change into a WhatsApp alternative, Musk responded merely that “X would be the every thing app.”

“X” right here refers to Musk’s plan to remodel Twitter right into a “tremendous app” that might mix funds, social networking, leisure, and extra into one singular expertise. Final week, he spoke in additional element about his plans for the funds portion, suggesting Twitter may at some point permit customers to carry money balances, ship cash to at least one one other, and even provide high-yield cash market accounts.
