[Message part 1 (text/plain, inline)]

Hi,

I was attempting to encrypt a file using multiple gpg subkeys, using the <subkey>! syntax supported by gpg. To do this, I had a file local variable in the 'file.gpg' I was editing that looked something like this:

--8<---------------cut here---------------start------------->8---
# -*- epa-file-encrypt-to: ("subkey0!" "subkey1!" "subkey2!") -*-
--8<---------------cut here---------------end--------------->8---

However, I found that this failed to select the subkeys, and would fall back to symmetric encryption. If I specify the subkeys without the '!' suffix, it ends up using the most recent subkey on the corresponding master.

This all to say, looking at the source, it appears this is expected behavior. It would be nice if explicitly specifying subkeys to use was supported.

Much thanks!
