   4         help
   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.

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

  27         help
  28           This option provides support for parsing X.509 format blobs for key
  29           data and provides the ability to instantiate a crypto key from a
  30           public key packet found inside the certificate.

  36         select OID_REGISTRY
  37         help
  38           This option provides support for parsing PKCS#7 format messages for
  39           signature data and provides the ability to verify the signature.

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

  52           This is intended for testing the PKCS#7 parser.

  61           signed PE binary.
