New tool makes Gmail messages self-destruct

Now, Gmail users can use “Dmail”, a Chrome extension that provides an alternate way to revoke access to an email sent. So what happens if you choose never and then realize you want to recall that email? In place of the revoked email content, the recipient can see a line about receiving a message via Dmail using the view message button in the Chrome tab.

With Dmail, you can delete an email you’ve already sent so no one can read it anymore. Once sent messages have been deleted through Dmail, they become unviewable to the recipient, who is sent an email that reads “this message has been destroyed and is no longer available”.

It works by simply delaying the sending of any email up to 30 seconds, but that may not cover all your tracks. If a message has been revoked, the email is tagged as unavailable viewing for all.

The messages sent via Dmail are locally encrypted on the user’s machine with a standard 256-bit encryption algorithm.

Additionally, Dmail allows users to recall sent emails at any time, whether the recipient has the function or not. The recipient of the email is sent both the location of that data store, as well as a key to view the decrypted message. Before sending it through the Dmail servers, the sender can set whether the message expires in a day, a week, or a month. The second option lets users destroy any specific email previously sent with Dmail.

With the popularity of such an extension guaranteed, the creators of Dmail, Delicious, are planning to add an update which will stop email recipients from forwarding emails.

Dmail plans to launch an iOS app in August, and follow it up with a version for Android.
