@delta I wish more apps and web mailers supported the AutoCrypt protocol. Like @GPGTools for the Mac, Open-Xchange (which powers @mailbox_org web mail and the Guard module inside it), etc. It would make secure OpenPGP key exchange so much easier, especially when key servers fail, like happened last week. I believe the handling of OpenPGP keys is still the greatest barrier to by default encrypted email and related communication.
