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 and encryption of ssh connection.
+for authentication of ssh connections.
\fBmonkeysphere\fP is the MonkeySphere client utility.
.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 none is found in the user's keychain. search
-for a gpg key for the host in the Web of Trust. If a key is found, it
-will be added to the host_keys cache (see KEY CACHES) and any ssh keys
-for the host will be removed from the user's known_hosts file. If the
-found key is acceptable (see KEY ACCEPTABILITY), then the host's gpg
-key will be 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-userids [USERID]...
-Add/update a user ID to the authorized_user_ids file. The user IDs
-specified should be exact matches to OpenPGP user IDs. For each
-specified user ID, gpg will be queried for a key associated with that
-user ID, querying a keyserver if none is found in the user's keychain.
-If a key is found, it will be added to the user_keys cache (see KEY
-CACHES) and the user ID will be added to the user's
-authorized_user_ids file (if it wasn't already present). `u' may be
-used in place of `update-userids'.
-.TP
-.B remove-userids [USERID]...
-Remove a user ID from the authorized_user_ids file. The user IDs
-specified should be exact matches to OpenPGP user IDs. `r' may be
-used in place of `remove-userids'.
+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. The monkeysphere
-authorized_keys file will be regenerated from the valid keys in the
-user_key cache, and the user's independently controlled
-authorized_keys file (usually ~/.ssh/authorized_keys). `a' may be
-used in place of `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
GPG keys are considered acceptable if the following criteria are met:
.TP
.B capability
-For host keys, the key must have both the "authentication" ("a") and
-"encrypt" ("e") capability flags. For user keys, the key must have
-the "authentication" ("a") capability flag.
+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 KEY CACHES
-
-Monkeysphere keeps track of keys in key cache directories. The files
-in the cache are named with the format "USERID_HASH.PUB_KEY_ID", where
-USERID_HASH is a hash of the exact OpenPGP user ID, and PUB_KEY_ID is
-the key ID of the primary key. If the user/key ID combo exists in the
-Web of Trust but is not acceptable, then the file is empty. If the
-primary key has at least one acceptable sub key, then an ssh-style
-key, converted from the OpenPGP key, of all acceptable subkeys will be
-stored in the cache file, one per line. known_hosts style key lines
-will be stored in the host_keys cache files, and authorized_keys style
-key lines will be stored in the user_keys cache files. OpenPGP keys
-are converted to ssh-style keys with the openpgp2ssh utility (see `man
-openpgp2ssh').
