   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.

  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.

  38         help
  39           This option provides support for parsing PKCS#8 format blobs for
  40           private key data and provides the ability to instantiate a crypto key
  41           from that data.

  48         help
  49           This option provides support for parsing PKCS#7 format messages for
  50           signature data and provides the ability to verify the signature.

  52 config PKCS7_TEST_KEY
  53         tristate "PKCS#7 testing key type"

  55         help
  56           This option provides a type of key that can be loaded up from a
  57           PKCS#7 message - provided the message is signed by a trusted key.  If
  58           it is, the PKCS#7 wrapper is discarded and reading the key returns
  59           just the payload.  If it isn't, adding the key will fail with an
  60           error.
  61
  62           This is intended for testing the PKCS#7 parser.

  72           signed PE binary.
