+	depends on KEYS
+	help
+	  This option provides support for a key type that holds the data for
+	  the asymmetric keys used for public key cryptographic operations such
+	  as encryption, decryption, signature generation and signature
+	  verification.

+config ASYMMETRIC_PUBLIC_KEY_SUBTYPE
+	tristate "Asymmetric public-key crypto algorithm subtype"
+	select MPILIB
+	select PUBLIC_KEY_ALGO_RSA
+	select CRYPTO_HASH_INFO
+	help
+	  This option provides support for asymmetric public key type handling.
+	  If signature generation and/or verification are to be used,
+	  appropriate hash algorithms (such as SHA-1) must be available.
+	  ENOPKG will be reported if the requisite algorithm is unavailable.
+
+config PUBLIC_KEY_ALGO_RSA
+	tristate "RSA public-key algorithm"
+	select MPILIB
+	help
+	  This option enables support for the RSA algorithm (PKCS#1, RFC3447).

+	tristate "X.509 certificate parser"
+	depends on ASYMMETRIC_PUBLIC_KEY_SUBTYPE
+	select ASN1
+	select OID_REGISTRY
+	help
+	  This option provides support for parsing X.509 format blobs for key
+	  data and provides the ability to instantiate a crypto key from a
+	  public key packet found inside the certificate.
+
+config PKCS7_MESSAGE_PARSER
+	tristate "PKCS#7 message parser"
+	depends on X509_CERTIFICATE_PARSER
+	select ASN1
+	select OID_REGISTRY
+	help
+	  This option provides support for parsing PKCS#7 format messages for
+	  signature data and provides the ability to verify the signature.
+
+config PKCS7_TEST_KEY
+	tristate "PKCS#7 testing key type"
+	depends on PKCS7_MESSAGE_PARSER
+	select SYSTEM_TRUSTED_KEYRING
+	help
+	  This option provides a type of key that can be loaded up from a
+	  PKCS#7 message - provided the message is signed by a trusted key.  If
+	  it is, the PKCS#7 wrapper is discarded and reading the key returns
+	  just the payload.  If it isn't, adding the key will fail with an
+	  error.
+
+	  This is intended for testing the PKCS#7 parser.
+
+config SIGNED_PE_FILE_VERIFICATION
+	bool "Support for PE file signature verification"
+	depends on PKCS7_MESSAGE_PARSER=y
+	select ASN1
+	select OID_REGISTRY
+	help
+	  This option provides support for verifying the signature(s) on a
+	  signed PE binary.
