Thats why you cannot expect them to understan PGP and PKI. You want a sane default that can secure 99% of people and expose the guts to the last 1% through options menus.<p>The perfect PGP secure email client would be cross platform and provide its own email server. The client has included trusted keys to communicate with upstream, but when you first start it you make your account and that generates you a signing and encryption key based off your password, backs it up on their server (remember, its password protected, they cannot access it despite backing it up) and then whenever you sign in on other device your keys are downloaded and just work.<p>This basically turns PGP into username &#x2F; password, but the only alternative is to use wifi to send your keys between devices when you first start your client of choice - IE, you start it for the first time, it says &quot;do you already have an account? You say yes and it simply asks which PC on the lan has your keys, it communicates with it, you confirm on the other computer to send the keys, and it synchronizes your keys cross-device peer to peer.<p>And I worry even that is too complicated for my grandmother to be willing to put up with to stop the NSA from reading her emails.
