Lavabit, a secure email service once used by NSA whistleblower Edward Snowden, has relaunched. Owner Ladar Levison decided to close the service in 2013 rather than comply with a government request for its SSL encryption keys. The government wanted to see Snowden's communications.
Compared to its prior version, Lavabit is now even more secure. It's set up so that it's physically impossible for its SSL key to be given to the authorities.
Lavabit is currently only open to previous users who were locked out when the service closed. New users will be accepted shortly.
Users will be given three general security options: Trustful, Cautious, and Paranoid. Cautious is the level at which end-to-end encryption is used.
