Again, you're tightly bound to GnuPG. Does EasyPG support arbitrary,
user-supplied ciphers? I didn't see that ability.

Definitely no. Again, you're tightly bound to GnuPG. Your README says:
"EasyPG is an all-in-one GnuPG interface for Emacs. It has two
aspects: convenient tools which allow to use GnuPG from Emacs (EasyPG
Assistant), and a fully functional interface library to GnuPG (EasyPG
Library)."
There's nothing wrong with that, but you're entirely dependent on GnuPG
to do the encryption and decryption, so you most definitely do not
provide the same services as encrypt.el.

It's not a fallback, it's an example implementation. I have not read
that particular book, but I have studied encryption algorithms in
college and have used them at the API level many times since.

Sorry, but you'll have to be patient with me. I did not get that
distinction from the EasyPG docs, perhaps I missed it.

We're talking in circles.
What you consider simplicity is in fact reliance on an external tool,
which handles everything for you. I think encryption and decryption
should be possible with an API, without external tools. If we disagree
and EasyPG is the only encryption API in Emacs, then I will keep
maintaining encrypt.el in the Gnus development tree.
