The developer behind Lavabit – an email service that noted leaker Edward Snowden used – is releasing source code for an open-source, end-to-end encrypted email standard that promises surveillance-proof messaging.
According to the reports, the code for the Dark Internet Mail Environment (DIME) standard will become available on Github, along with an associated mail server program. The news was announced by its developer Ladar Levison, on Friday. DIME will work across different service providers.
To coincide with its launch, Levison is also reviving Lavabit. The encrypted email service shut down in 2013 when federal agents investigating Snowden demanded access to email messages of his 410,000 customers, including their private encryption keys.
The revived Lavabit is also built with DIME, which Levison started with a Kickstarter fund in 2014. It is designed to encrypt the email and its transmission, including the metadata such as the message’s subject line, sender and recipient.
The new Lavabit will operate in three encryption modes that range from Trustful, Cautious to Paranoid. Each mode handles message encryption and private key storage differently at the expense of ease of use.
