87	  - A pkey base and API kernel module (pkey.ko) which offers the

89	    and the sysfs API and the in-kernel API to the crypto cipher
90	    implementations using protected key.

148
149	  The PCKMO way of deriving protected keys from clear key material
150	  is especially used during self test of protected key ciphers like
