That is simple, indeed. But how do you exchange passphrases for
the encrypted files in advance and do you switch them regularly
or leave them the same when dealing with many clients?

I solved this with using NaCl public keys, bearing no infos of
the key owners and having a little key ring, where I only assign
nicknames to the pub keys. The software I use is box

in combination with a base91 encoder / decoder, for ASCII armor,
when sending encrypted emails. 

Before that I also experimented with other tools, like dhbitty,
MiniLock and Pretty Curved Privacy etc. but for me they all had
some disadvantages compared to box.
