 If you have a GPG key configured on your local system and are sending a direct message to someone who has a PGP key (the exported key, not just the key ID) set as a tag on their profile then it will try to encrypt the message automatically. So under some conditions end-to-end encryption is possible, such that the instance server only sees ciphertext. Conversely, for arriving direct messages if they are PGP encrypted then the notification client will try to obtain the relevant public key and decrypt.
