6 Profanity - a simple console based XMPP chat client.

9 This man page is intended to help you set up XEP-0374: OpenPGP for XMPP
10 Instant Messaging. Also known as OX.
11 For details on usage see man profanity-ox or /help ox.
13 Profanity wants to give the user a maximum freedom in setting up their
15 system. So we won’t touch your GPG settings directly. Which means you
16 will need to do some manual steps. They are described here
17
19 The first step is to create a OpenPGP key pair. The key pair genera‐
20 tion will be done with the gpg command of GnuPG.
21 gpg --quick-generate-key xmpp:alice@domain.tld future-default default 3y
23 This command will generated a OpenPGP key with a UID xmpp:alice@do‐
25 main.tld. The option future-default has been used to generate a
26 ed25519/cv25519 key. The key is set to expire in threeyears.
27 Replace the Jabber ID with your JID and do not forget the URI xmpp:
29 prefix.
30 Example output:
32 pub ed25519 2021-09-21 [SC] [verfällt: 2024-09-20]
34 583BAE703A801095B6B71A56BD801174B1A0B84A
35 uid xmpp:alice@domain.tld
36 sub cv25519 2021-09-21 [E]

39 You need to export your public key so you can later upload it into a
40 PEP node. It’s just a way how your chat partners can retrieve the pub‐
41 lic key from you. Use the command below to export public key:
42 Example command:
44 gpg --export \
46 --export-options export-minimal \
47 --export-filter 'keep-uid=uid =~ xmpp:alice@domain.tld' \
48 --export-filter 'drop-subkey=usage =~ a' \
49 583BAE703A801095B6B71A56BD801174B1A0B84A \
50 > /tmp/pep-key.gpg
51 The key will be exported to /tmp/pep-key.gpg. You may check the key
53 with the command below:
54 gpg --show-key --with-sig-list /tmp/pep-key.gpg
56 Keep in mind: Public keys may have some information (signatures, name,
58 e-mail address). Be careful which data will be exported. The export-
59 options and export-filter option of GnuPG will help you to filter the
60 data.
61
63 You can use profanity to publish your exported key into your account
64 (PEP). The /ox announce command will publish your key.
65 /ox announce /tmp/pep-key.gpg
67 The command will create two PEP node records to store the key.
69
71 To discover public keys of your partners use the /ox discover command.
72 Example output:
74 /ox discover buddy@domain.tld
76 Discovering Public Key for buddy@domain.tld
77 1234567890ABCDEF1234567890ABCDEF12345678
78 To request and import a key, you can use the /ox request command.
80 /ox request buddy@domain.tld 1234567890ABCDEF1234567890ABCDEF12345678
82 Requesting Public Key 1234567890ABCDEF1234567890ABCDEF12345678 for buddy@domain.tld
83 Public Key imported
84 The key will be imported into your gnupg keyring.
86
88 The key can been shown via gpg gpg -k xmpp:buddy@domain.tld. Make sure
89 the key is the key of your buddy and sign the key with your key.
90 gpg --ask-cert-level --default-key 583BAE703A801095B6B71A56BD801174B1A0B84A --sign-key 1234567890ABCDEF1234567890ABCDEF12345678
92 The command /ox contacts will show the keys with XMPP-UID. The command
94 /ox keys will show all known OpenPGP keys.
95 Only once you signed the key you can actually use OX with your partner.
97
99 Within a chat window you can start OX via /ox start and stop it via /ox
100 end.
101 Messages will be send signed and encrypted.
