"Two email providers forced to close their services in the wake of the Edward Snowden revelations on mass surveillance have proposed a new open standard for secure email that would be harder for security services and others to eavesdrop upon.
The encrypted email service Lavabit, and Silent Circle, a firm also encrypting phone calls and texts, are the founding members of the Darkmail Alliance, a service that aims to prevent government agencies from listening in on the metadata of emails".
