“Generally you don’t want to share the same key across multiple devices,” Green wrote (confession, we didn’t bother to PGP-encrypt our e-mails). “There needs to be a mechanism for registering many devices, for ensuring that nobody adds a device you don’t want, etc.”įor example, while I can use GPG Suite on multiple Macs to encrypt e-mail messages using the Pretty Good Privacy standard, doing so requires me to have multiple copies of the private key at the root of this cryptography system. It’s just that adding multiple devices adds a lot of complexity,” explained Matthew Green, a cryptography professor at Johns Hopkins University whom Facebook paid to help with the project. So, really, every Secret Conversation is potentially self-destructing until future versions address this. Enabling the app on a new device wipes previous encrypted messages off the old one, and even a full, encrypted backup of an iOS device to iTunes will not preserve them. Unfortunately, Secret Conversations are chained to one device in a way that other encryption setups - including WhatsApp’s - are not.

(Security-minded Facebook friends, come at me.)

Even the announced limited scale of the trial turns out to matter little when anybody with this feature can invite friends to use it. Note that you’ll keep sending self-destructing messages to this person unless you tap the clock icon again and switch the timer to “Off.” Issues and limitationsįacebook’s Secret Conversation is vastly easier than other encrypted options - and has the virtue of coming in an app that, as Facebook just bragged, 1 billion people use a month. A clock will count down on both devices, after which the message vanishes … unless the recipient takes a screenshot of it.

You can also set a message to self-destruct after it’s been viewed - your options range from 5 seconds to a day - by tapping the clock icon to its right. Edward Snowden has repeatedly endorsed Signal on Twitter, and the Electronic Frontier Foundation gave it a perfect score in last year’s “secure messaging scorecard.”Ī Secret Conversation can include photos, emoji, thumbs-up Likes and stickers, but not voice calls, video or group conversations.

Facebook built this function using Signal, open-source software developed by Open Whisper Systems with help from $2.3 million in funding from the government-backed Open Technology Fund.
