usage: ceph-authtool keyringfile [OPTIONS]...
where the options are:
-l, --list will list all keys and capabilities present in
the keyring
-p, --print-key will print an encoded key for the specified
entityname. This is suitable for the
'mount -o secret=..' argument
-C, --create-keyring will create a new keyring, overwriting any
existing keyringfile
-g, --gen-key will generate a new secret key for the
specified entityname
-t, --key-type KEY_TYPE set the key-type
--gen-print-key will generate a new secret key without set it
to the keyringfile, prints the secret to stdout
--import-keyring FILE will import the content of a given keyring
into the keyringfile
-n NAME, --name NAME specify entityname to operate on
-a BASE64, --add-key BASE64 will add an encoded key to the keyring
--cap SUBSYSTEM CAPABILITY will set the capability for given subsystem
--caps CAPSFILE will set all of capabilities associated with a
given key, for all subsystems
--mode MODE will set the desired file mode to the keyring
e.g: '0644', defaults to '0600'

Examples (4) from the manual page, untested
ceph-authtool -C -n client.foo --gen-key keyring --mode 0644
To create a new keyring containing a key for client.foo with a 0644 file mode:ceph-authtool -n client.foo --cap mds 'allow' --cap osd 'allow rw pool=data' --cap mon 'allow r' keyring
To associate some capabilities with the key (namely, the ability to mount a Ceph file system):ceph-authtool -l keyring
To display the contents of the keyring:mount -t ceph serverhost:/ mountpoint -o name=foo,secret=`ceph-authtool -p -n client.foo keyring`
When mounting a Ceph file system, you can grab the appropriately encoded secret key with:
