Encryption Problem

Reported by matthias | September 27th, 2018 @ 10:29 AM

I'm trying to send an encrypted message and get the following error:
INV_RECP 0 recipient@domain.tls
FAILURE encrypt 53

The key is valid, but I can't encrypt, what to do?

    Sorry about the very late response!

    Error codes from GNUPG are not always informative. According to a header file then 53 means GPG_ERR_UNUSABLE_PUBKEY.

    Does this only happen for a specific recipient or all recipients?

    If you want I can provide instructions to get a command line for the Terminal with which you can more easily experiment -- if you are a Terminal user.

    I had as similar issue where the recipient used a different domain for GPG mails. I only found out after examining the output of the key list

    gpg -k

    and copied the desired email address from there.

    Thanks for the hint. Perhaps it'll be useful for people googling the same issue.
