# Profanity - OpenPGP for XMPP
|
||||
|
||||
Implementation of XEP-0373 - OpenPGP for XMPP (OX) in profanity.
|
||||
|
||||
## Overview
|
||||
The current version (2020-05-23) of profanity provides *XEP-0027: Current Jabber
|
||||
OpenPGP Usage* via the `/pgp` command. This XEP is *Obsolete*. We should
|
||||
implement *XEP-0373 - OpenPGP for XMPP (OX)* in profanity.
|
||||
|
||||
## pgp
|
||||
|
||||
```
|
||||
14:37:52 - Synopsis
|
||||
14:37:52 - /pgp libver
|
||||
14:37:52 - /pgp keys
|
||||
14:37:52 - /pgp contacts
|
||||
14:37:52 - /pgp setkey <contact> <keyid>
|
||||
14:37:52 - /pgp start [<contact>]
|
||||
14:37:52 - /pgp end
|
||||
14:37:52 - /pgp log on|off|redact
|
||||
14:37:52 - /pgp char <char>
|
||||
14:37:52 -
|
||||
14:37:52 - Description
|
||||
14:37:52 - Open PGP commands to manage keys, and perform PGP encryption during chat sessions. See the /account command to set your own PGP key.
|
||||
14:37:52 -
|
||||
14:37:52 - Arguments
|
||||
14:37:52 - libver : Show which version of the libgpgme library is being used.
|
||||
14:37:52 - keys : List all keys known to the system.
|
||||
14:37:52 - contacts : Show contacts with assigned public keys.
|
||||
14:37:52 - setkey <contact> <keyid> : Manually associate a contact with a public key.
|
||||
14:37:52 - start [<contact>] : Start PGP encrypted chat, current contact will be used if not specified.
|
||||
14:37:52 - end : End PGP encrypted chat with the current recipient.
|
||||
14:37:52 - log on|off : Enable or disable plaintext logging of PGP encrypted messages.
|
||||
14:37:52 - log redact : Log PGP encrypted messages, but replace the contents with [redacted]. This is the default.
|
||||
14:37:52 - char <char> : Set the character to be displayed next to PGP encrypted messages.
|
||||
```
|
||||
## OX
|
||||
We should implement the `/ox` command which can be used for XEP-0373 instead of
|
||||
XEP-0027.
|
||||
|
||||
```
|
||||
/ox keys - List all public keys known to the system (gnupg's keyring)
|
||||
/ox contacts - Shows contacts with an assigned public key.
|
||||
```
|
||||
|
||||
The `keys` command will list all public keys of gnupg's Keyring, independent if
|
||||
the key is in use for XMPP or not.
|
||||
|
||||
In profanity we are going to implement the key lookup with a XMPP-URI as OpenPGP
|
||||
User-ID. An OpenPGP public key can only be used, if the owner of the public key
|
||||
created an User-ID with the XMPP-URI as Name. https://xmpp.org/extensions/xep-0373.html#openpgp-user-ids
|
||||
It's not required and possible to assign a contact to an public key.
|
||||
|
||||
```
|
||||
sec rsa3072 2020-05-01 [SC] [verfällt: 2022-05-01]
|
||||
7FA1EB8644BAC07E7F18E7C9F121E6A6F3A0C7A5
|
||||
uid [ ultimativ ] Doctor Snuggles <doctor.snuggles@domain.tld>
|
||||
uid [ ultimativ ] xmpp:doctor.snuggles@domain.tld
|
||||
ssb rsa3072 2020-05-01 [E] [verfällt: 2022-05-01]
|
||||
```
|
||||
|
||||
The `contacts` command will show all contacts of the roster with a public key in
|
||||
the keyring, if there is a xmpp user-id within the public key.
|
||||
|
||||
OX provides the elements: `<signcrypt/>`, `<sign/>` and `<crypt/>`. Profanity
|
||||
implements signcrypt, only.
|
||||
|
||||
|
||||
## Keys command
|
||||
The command `keys` is independent of the XEP. Should we move common commands
|
||||
(e.g. /pgp keys /ox keys) to /openpgp which will will be the function which are
|
||||
related to gnupg itself.
