What gpg file format to import gpg keys into email account?

Hello,
i have some gpg keys for my email accounts on my linux.
Exporting it from thunderbird creates .asc files with

-----BEGIN PGP PUBLIC KEY BLOCK-----
...
-----END PGP PUBLIC KEY BLOCK-----

and

-----BEGIN PGP PRIVATE KEY BLOCK-----
...
-----END PGP PRIVATE KEY BLOCK-----

section.
Importing the files via settings → accounts → import did not work.
I did not find which file format is required for the import.

Many thanks for any help gabs5807

I think you can just copy the .gnupg folder to your home$.
I guess you will need some patch in order to sign mails from the genuine email client.

Thank you for the information.
I take a look to the gnupg sides and tried to import my key to the keyring.

gpg2 --import xxx@yyy-ABCDEF00.asc 
gpg: Ohhhh jeeee: mpi larger than packet

The problem is that the newer keys could not be imported because the gpg2 is to old :roll_eyes:

root@fp2-4:~ # gpg2 --version
gpg (GnuPG) 2.0.4 
...

The fix for my problem is on 2.0.28 release.

For me email encryption is a essential thing that should work :roll_eyes:.
Everybody talk about e2e encryption for various chat tools but the easiest implementation (for email) did not work? Very strange …

But many thanks again gabs5807

Unfortunately Jolla will stay on that ancient release because GNU changed the license to GPL3 after that.

Also, there is no support for encrypted emails in the Jolla Email application. GPG can only be used for signing and verifying signatures.

Many thanks for the info.
This is very sad :frowning_face:. With this approach the system will become unusable sooner or later :face_with_raised_eyebrow:.
