Doesn't it work without any change? epa-file changes
insert-file-contents behavior to decrypt *.gpg files automatically.
For example, I believe that the following code just works:
(epa-file-enable);; this may become (auto-encryption-mode t) in the future.
(setq nnimap-authinfo-file "~/.authinfo.gpg"
nntp-authinfo-file "~/.authinfo.gpg"
smtpmail-auth-credentials "~/.authinfo.gpg")
What feature do you want in addition to this?

If all the custom-options should be documented in texi, I will do it.

Which are you talking about: user commands or API?
As the web-page says, EasyPG is consists of two different kinds of
components: EasyPG Assistant and EasyPG Library. EasyPG Assistant is
an analog to GPA and EasyPG Library is an analog to GPGME.
Since IIRC Richard doesn't want API docs in texi, I only provide the
docs of EasyPG Assistant (user commands) and I think that epa.texi is
sufficient for typical users.
Anyway, a good starting point to use the EasyPG Library is the GPGME manual.

There is no such API in lisp level, since I doubt that there is any
practical use to select ciphers per data. Is it not enough to put
cipher-algo option in ~/.gnupg/gpg.conf?

Just pass nil as RECIPIENTS to the epg-encrypt-*. This is documented
in their docstrings.

s/plaintext/ASCII armor/? It can be done with:
(let ((epg-make-context 'OpenPGP))
(epg-context-set-armor t)
(epg-encrypt-string context "test test test" nil))

There are API functions epg-generate-key-from-*, but interactive
commands are missing. Patches welcome.
