That's the basic question.
Basic answer: good local random source, Diffie-hellman exchange with
out-of-band public key integrity check, conventional AES encryption with
AEAD scheme. This is the implementation I came with when I felt the need
to do the exercise of addressing the basic question as simply as possible.
Otherwise, train users with GPG (untrained users will be exposed to data
leaks in any scheme).
