Subject: 31.0.50; epa-dired is not tramp-aware
Date: Sat, 2 Aug 2025 22:02:38 +0530

The epa-dired commands like epa-dired-do-decrypt do not work in the
dired buffer under tramp.

Steps to reproduce:

1. Open the dired buffer over tramp using
   /ssh:user <at> hostname:/path/to/directory
2. Mark the file with the .gpg extension in the dired buffer using
   dired-mark.
3. Call the M-x epa-dired-do-decrypt command.

Behavior:

It appears like epa-dired is passing the tramp-path verbatim to the gpg.
I've updated the tramp-path to remove identifiers.

Error while decrypting with "/opt/homebrew/bin/gpg":

gpg: can't open '/ssh:user <at> hostname:/path/to/file.gpg': No such file
or directory
gpg: decrypt_message failed: No such file or directory

Expected Behavior:

I expected the command to be aware of Tramp paths. In case of Tramp
files:
1. Write the file to a temporary local file
2. Decrypt it using local GPG keys.
3. Write the decrypted file back to the remote location with the file name
   accepted as the input.

Alternatively, we could let gpg run on the remote host.

In my use-case, I don't have the GPG keys configured on the remote host. The
remote host may not even have GPG installed.

Potentially, it can be exposed as a flag in the function to determine which GPG
to use.

I don't use epa in Emacs; my opinion doesn't count. However, as a naïve
user I would expect the gpg keys to be on the same host as the encrypted
files.

Sounds more complicate. Let the epa maintainer decide what's best.

Best regards, Michael.
