First, make sure that your Pinentry is 0.9.5 or later.  Secondly, add
allow-emacs-pinentry to your ~/.gnupg/gpg-agent.conf.  Finally, start
the Emacs Pinentry server with M-x pinentry-start.

Then, you should be able to interact with gpg through minibufer.  Try
M-x shell and run gpg from there (or do M-x epa-encrypt-region, etc.).

If it doesn't work well, let me know (I expect that there are still
rough edges).
