-.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').
