Description

I'm trying to encrypt my mails. So :

1. I have entered my public key on the UI
2. I have created the keys on the server using docker compose exec --user anonaddy anonaddy gpg --full-gen-key, I've even tried docker compose exec --user anonaddy anonaddy gpg --full-gen-key --passphrase=''
3. Impossible to finish the key creation, as GPG requires a passphrase
4. As there is a passphrase, AnonAddy can't use the key and we get this error :

[2023-11-25 16:50:35] production.ERROR: encrypt-sign failed {"exception":"[object] (Exception(code: 0): encrypt-sign failed at /var/www/anonaddy/app/CustomMailDriver/Mime/Crypto/OpenPGPEncrypter.php:248)

Expected behaviour

We should either be able to create GPG keys with passphrase, or be able to create GPG keys without passphrase (hte former solution is of course the better)

Actual behaviour

Unable to send crypted emails

Steps to reproduce

1. Try to create a private key usable by AnonAddy

The only solution I've found so far is to create the key outside of the AnonAddy docker container, and import it with docker compose exec --user anonaddy anonaddy gpg --import
