  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.

 15         select CRYPTO_HASH_INFO
 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.

 25         select ASN1
 26         select OID_REGISTRY
 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.

 32 config PKCS7_MESSAGE_PARSER
 33         tristate "PKCS#7 message parser"
 34         depends on X509_CERTIFICATE_PARSER
 35         select ASN1
 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.

 41 config PKCS7_TEST_KEY
 42         tristate "PKCS#7 testing key type"
 43         depends on PKCS7_MESSAGE_PARSER
 44         select SYSTEM_TRUSTED_KEYRING
 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.
 51 
 52           This is intended for testing the PKCS#7 parser.

 58         select OID_REGISTRY
 59         help
 60           This option provides support for verifying the signature(s) on a
 61           signed PE binary.
