Description

It is currently possible to get GPG encryption working with a key, by setting the switches manually like this:

--encryption-module=gpg
--gpg-encryption-command=--encrypt
--gpg-encryption-switches=--recipient "xxx@zzz.com"
--gpg-decryption-command=--decrypt
--passphrase=unused

You also need to set the trust level of the key to 5, for example:

gpg --edit-key "xxx@zzz.com" trust

It would be nice if there was a module, say gpg-pubkey or similar that simply sets these options. Perhaps the passphrase could be used for the recipient, but that might get messy if you want to change it later.

Contributor guide

Research direction
Study the existing GPG encryption module in Duplicati to understand how encryption modules are structured. Then create a new module (e.g., "gpg pubkey") that sets the command line options for asymmetric encryption using a recipient key. Ensure the module properly handles key trust and passphrase configuration.
