   7           the asymmetric keys used for public key cryptographic operations such
   8           as encryption, decryption, signature generation and signature

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

  31           data and provides the ability to instantiate a crypto key from a

  47           This option provides a type of key that can be loaded up from a
  48           PKCS#7 message - provided the message is signed by a trusted key.  If
  49           it is, the PKCS#7 wrapper is discarded and reading the key returns
  50           just the payload.  If it isn't, adding the key will fail with an
  51           error.
