   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.

  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.

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

  37         select OID_REGISTRY
  38         help
  39           This option provides support for parsing PKCS#7 format messages for
  40           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           This option provides support for verifying the signature(s) on a
  62           signed PE binary.
