Does anyone know how to make the Emacs encryption commands such as
epa-decrypt-region work with gpg-agent on a text console?
If I start gpg-agent in the usual way before running Emacs,
then when I try to decrypt, gpg-agent and Emacs both try to
read from the terminal so the passphrase always gets garbled.

I use a setup where all my Emacs based decryption (epa) commands are
from the (text/tty Emacs) password input prompt in Emacs, and sent to
gpg-agent. This works for me over SSH, tty1-6, or in an X session
terminal emulator (no call out to the GUI password input prompt).
More recent versions of Emacs/gpg-agent required me to add the loopback
option, as well as the Emacs options - a couple years ago it worked with
just the allow-emacs-pinentry setting and nothing else:
My relevant settings are as follows:
In ~/.gnupg/gpg-agent.conf:
allow-emacs-pinentry
allow-loopback-pinentry
On the Emacs side:
(setq epa-pinentry-mode 'loopback)
(pinentry-start) ; This was disabled recently in Emacs 26+ and has to be
explicitly called
I know I ran into many garbled text issues when trying to combine
ncurses input on the gpg-agent with Emacs functions.

AFAIK, currently (Emacs master, GnuPG 2.2.8) only `(setq
epg-pinentry-mode 'loopback)' should be needed (that's what I have).
So, no explicit configuration in gpg-agent.conf.

Thanks for showing me this. I tried it and discovered that somehow
I have GPG version 1 installed and can't install version 2. When I get
that installed, I will try your solution again.
