NAME

       Profanity - a simple console based XMPP chat client.

DESCRIPTION

       This man page is intended to help you set up XEP-0374: OpenPGP for XMPP Instant Messaging.
       Also known as OX.

       For details on usage see man profanity-ox or /help ox.

       Profanity wants to give the user a maximum freedom in setting  up  their  system.   So  we
       won’t  touch  your  GPG  settings  directly.   Which means you will need to do some manual
       steps.  They are described here

Generate OpenPGP key materials

       The first step is to create a OpenPGP key pair.  The key pair generation will be done with
       the gpg command of GnuPG.

              gpg --quick-generate-key xmpp:alice@domain.tld future-default default 3y

       This  command  will  generated a OpenPGP key with a UID xmpp:alice@domain.tld.  The option
       future-default has been used to generate a ed25519/cv25519 key.  The key is set to  expire
       in threeyears.

       Replace the Jabber ID with your JID and do not forget the URI xmpp: prefix.

       Example output:

              pub   ed25519 2021-09-21 [SC] [verfällt: 2024-09-20]
                    583BAE703A801095B6B71A56BD801174B1A0B84A
              uid                      xmpp:alice@domain.tld
              sub   cv25519 2021-09-21 [E]

Export your public key

       You  need to export your public key so you can later upload it into a PEP node.  It’s just
       a way how your chat partners can retrieve the public key from you.  Use the command  below
       to export public key:

       Example command:

              gpg --export \
                --export-options export-minimal \
                --export-filter 'keep-uid=uid =~ xmpp:alice@domain.tld' \
                --export-filter 'drop-subkey=usage =~ a' \
                583BAE703A801095B6B71A56BD801174B1A0B84A \
                > /tmp/pep-key.gpg

       The  key  will  be  exported  to /tmp/pep-key.gpg.  You may check the key with the command
       below:

       gpg --show-key --with-sig-list /tmp/pep-key.gpg

       Keep in mind: Public keys may have some information (signatures,  name,  e-mail  address).
       Be  careful  which  data will be exported.  The export-options and export-filter option of
       GnuPG will help you to filter the data.

Publish your key

       You can use profanity to publish your exported key  into  your  account  (PEP).   The  /ox
       announce command will publish your key.

              /ox announce /tmp/pep-key.gpg - the Profanity /ox announce /tmp/pep-key.gpg command.

       The command will create two PEP node records to store the key.

Discover keys

       To discover public keys of your partners use the /ox discover command.

       Example output:

              /ox discover buddy@domain.tld
              Discovering Public Key for buddy@domain.tld
              1234567890ABCDEF1234567890ABCDEF12345678

       To request and import a key, you can use the /ox request command.

              /ox request buddy@domain.tld 1234567890ABCDEF1234567890ABCDEF12345678
              Requesting Public Key 1234567890ABCDEF1234567890ABCDEF12345678 for buddy@domain.tld
              Public Key imported

       The key will be imported into your gnupg keyring.

Sign the imported key

       The key can been shown via gpg gpg -k xmpp:buddy@domain.tld.  Make sure the key is the key
       of your buddy and sign the key with your key.

              gpg --ask-cert-level --default-key 583BAE703A801095B6B71A56BD801174B1A0B84A --sign-key 1234567890ABCDEF1234567890ABCDEF12345678

       The command /ox contacts will show the keys with XMPP-UID.  The command /ox keys will show
       all known OpenPGP keys.

       Only once you signed the key you can actually use OX with your partner.

Use OX

       Within a chat window you can start OX via /ox start and stop it via /ox end.

       Messages will be send signed and encrypted.
