A lot has been made recently over the NSA’s actions, but regardless of which side of the fence you’re on, having the option for secure, encrypted emails is always important. It’s possible that Lavabit wasn’t as secure as it was marketed to be, but that doesn’t mean that we should ignore the importance of encryption, especially in this day and age.
Will we ever have truly private and secure email?
Despite the use of cryptography, Lavabit is also vulnerable to all three just like a conventional (unencrypted) e-mail service. The operator can, at any time, stop averting their eyes, an attacker who compromises the server can log the password a user transmits, and an attacker who can intercept communication to the server can obtain the password as well as the plaintext e-mail.
