   5           This option provides support for a key type that holds the data for
   6           the asymmetric keys used for public key cryptographic operations such
   7           as encryption, decryption, signature generation and signature
   8           verification.

  18           This option provides support for asymmetric public key type handling.
  19           If signature generation and/or verification are to be used,
  20           appropriate hash algorithms (such as SHA-1) must be available.
  21           ENOPKG will be reported if the requisite algorithm is unavailable.

  37           data and provides the ability to instantiate a crypto key from a
  38           public key packet found inside the certificate.
