Replace custom XOR key keyring encryption with `gpg` #8

Problem

We use a custom scheme to decrypt/encrypt the backup keyring. We could do it using gpg, that way the password would be cached and will not be stored in the application memory.

Solution

Replace custom code in encryption package with shell calls to gpg.
- Could not find standard lib for gpg

gpg-agent interface is too limited cannot set a custom prompt for each type of password. Left custom code.
