A few startups ago I was involved with a secure email company. We competed against a company called Hushmail. Their claim to fame is:
With Hushmail, users need only create and remember their own passphrases, and the secure Hushmail server does the rest. Encryption and decryption are transparent to the user, making Hushmail the most user-friendly secure mail solution available.
Unless of course Hushmail decrypts your email and gives it to the government.
A court document in a drug smuggling case has shown that the private email service Hushmail has been cooperating with police in handing over user emails..
I've always thought it is more important to prove who you are by actions rather than proclaim.
