decrypt a file with hidden key (EPA)

decrypt a file with hidden key (EPA)

[Philipp Haselwarter]

Hi,

I'm trying to use emacs to decrypt a file that was encrypted with gpg's
hidden-encrypt-to option, i.e. the file doesn't tell which key it was
encrypted for. But epa doesn't query me for a key to use during
decryption, it just fails with

> Error while decrypting with "gpg":
> 
> gpg: encrypted with RSA key, ID 00000000
> gpg: decryption failed: No secret key

Can EPA be configured to deal with this? Or is there something smart in
my gpg.conf missing?

cheers,

+1  (I'm also interested in answers to these questions.)

Sidenote:  Actually it is possible to decrypt a file which has been
encrypted with the hidden-encrypt option by referencing the key
explicitly.  E.g. concretely

gpg --try-secret-key 3E7C2CBACBABDA5BD6995A4C49010A040A3AE6F2 encrypted.file.gpg
