I came across an interesting blockchain project named Dmail. Dmail is an easy to use and a truly decentralized blockchain Email service that uses blockchain technology to encrypt, secure and revocable emails. Currently works only with Gmail through Google Chrome Browser.
Emails sent using Dmail will have a self destructive feature, where users can chose an expiration time of the sent emails. The timer begins as soon as the email is sent, and once the timer is up, the email gets deleted.
Dmail Technical Overview
Dmail uses Blockstack decentralized identities that can be linked to GitHub and social profiles, as well as cryptocurrency addresses, in a way that the user controls.
Dmail messages are encrypted. And, with Blockstack’s storage system, only the DID holder has access to any related data.
Dmail is installed through a Google chrome extension that will encrypt your message locally on your computer. The encrypted body of the message is sent to Dmail’s servers, while the decryption key and a link are sent to the intended recipients through Gmail. Neither Dmail nor Gmail gets both the encrypted message and the decryption key, so only the sender and intended recipients can read the message legibly.
How To Use Dmail in Five Easy Steps
2- Once the extension is installed, a small Dmail icon will appear on the Chrome browser
3- You are almost done. Everytime you compose/write a new email through gmail, you will get the screen bellow where you can chose to encrypt your email through Dmail’s service and for how long the sent email will be active before getting deleted.
4- The email recipient will receive an email like bellow. In order for him to view the received email, the recipient will need to click the attached link to open the email in a separate window.
5- The sender will always have the ability to Revoke and to Delete the sent emails. You can do so by opening the sent items tab on chrome, and open and email sent through Dmail.
Clicking Delete, will permanently delete the sent emails.
