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

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

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

  52         select SYSTEM_TRUSTED_KEYRING
  53         help
  54           This option provides a type of key that can be loaded up from a
  55           PKCS#7 message - provided the message is signed by a trusted key.  If
  56           it is, the PKCS#7 wrapper is discarded and reading the key returns
  57           just the payload.  If it isn't, adding the key will fail with an
  58           error.
  59
  60           This is intended for testing the PKCS#7 parser.
