   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.

  17         help
  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.

  27           This option enables support for the RSA algorithm (PKCS#1, RFC3447).

  34         help
  35           This option provides support for parsing X.509 format blobs for key
  36           data and provides the ability to instantiate a crypto key from a
  37           public key packet found inside the certificate.

  44         help
  45           This option provides support for parsing PKCS#7 format messages for
  46           signature data and provides the ability to verify the signature.

  51         select SYSTEM_TRUSTED_KEYRING
  52         help
  53           This option provides a type of key that can be loaded up from a
  54           PKCS#7 message - provided the message is signed by a trusted key.  If
  55           it is, the PKCS#7 wrapper is discarded and reading the key returns
  56           just the payload.  If it isn't, adding the key will fail with an
  57           error.

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

  65         select OID_REGISTRY
  66         help
  67           This option provides support for verifying the signature(s) on a
  68           signed PE binary.
