.SH NAME

monkeysphere \- MonkeySphere client user interface

.SH SYNOPSIS

.B monkeysphere \fIcommand\fP [\fIargs\fP]

.SH DESCRIPTION

MonkeySphere is a system to leverage the OpenPGP Web of Trust for ssh
authentication and encryption.  OpenPGP keys are tracked via GnuPG,
and added to the ssh authorized_keys and known_hosts files to be used
for authentication of ssh connections.

\fBmonkeysphere\fP is the MonkeySphere client utility.

.SH SUBCOMMANDS

\fBmonkeysphere\fP takes various subcommands:
.TP
.B update-known_hosts [HOST]...
Update the known_hosts file.  For each specified host, gpg will be
queried for a key associated with the host URI (see HOST URIs),
querying a keyserver if specified.  If a key is found, it will be
converted to an ssh key, and any matching ssh keys will be removed
from the user's known_hosts file.  If the found key is acceptable (see
KEY ACCEPTABILITY), then the key will be updated and re-added to the
known_hosts file.  If no gpg key is found for the host, then nothing
is done.  If no hosts are specified, all hosts listed in the
known_hosts file will be processed.  `k' may be used in place of
`update-known_hosts'.
.TP
.B update-authorized_keys
Update the monkeysphere authorized_keys file.  For each user ID in the
user's authorized_user_ids file, gpg will be queried for keys
associated with that user ID, querying a keyserver if specified.  If a
key is found, it will be converted to an ssh key, and any matching ssh
keys will be removed from the user's authorized_keys file.  If the
found key is acceptable (see KEY ACCEPTABILITY), then the key will be
updated and re-added to the authorized_keys file.  If no gpg key is
found for the user ID, then nothing is done.  `a' may be used in place
of `update-authorized_keys'.
.TP
.B gen-subkey KEYID
Generate an `a` capable subkey.  For the primary key with the
specified key ID, generate a subkey with "authentication" capability
that can be used for MonkeySphere transactions.  `g' may be used in
place of `gen-subkey'.
.TP
.B help
Output a brief usage summary.  `h' or `?' may be used in place of
`help'.

.SH HOST URIs

Host OpenPGP keys have associated user IDs that use the ssh URI
specification for the host, ie. "ssh://host.full.domain".

.SH KEY ACCEPTABILITY

GPG keys are considered acceptable if the following criteria are met:
.TP
.B capability
The key must have the "authentication" ("a") usage flag set.
.TP
.B validity
The key must be "fully" valid, and must not be expired or revoked.

.SH FILES

.TP
~/.config/monkeysphere/monkeysphere.conf
User monkeysphere config file.
.TP
/etc/monkeysphere/monkeysphere.conf
System-wide monkeysphere config file.
.TP
~/.config/monkeysphere/authorized_user_ids
OpenPGP user IDs associated with keys that will be checked for
addition to the authorized_keys file.
