+menuconfig ASYMMETRIC_KEY_TYPE
+	bool "Asymmetric (public-key cryptographic) key Support"
+	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.
+
+if ASYMMETRIC_KEY_TYPE
+
+config ASYMMETRIC_PUBLIC_KEY_SUBTYPE
+	bool "Asymmetric public-key crypto algorithm subtype"
+	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 RSA_PUBLIC_KEY_PARSER
+	bool "RSA public key parser"
+	depends on ASYMMETRIC_PUBLIC_KEY_SUBTYPE
+	select ASN1_DECODER
+	select ASN1_COMPILER
+	select OID_REGISTRY
+	help
+	  This option provides support for parsing a blob containing RSA
+	  public key data and provides the ability to instantiate a public
+	  key.
+
+config X509_CERTIFICATE_PARSER
+	bool "X.509 certificate parser"
+	depends on ASYMMETRIC_PUBLIC_KEY_SUBTYPE
+	select ASN1_DECODER
+	select ASN1_COMPILER
+	select OID_REGISTRY
+	select LIB_DATE
+	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
+	bool "PKCS#7 message parser"
+	depends on X509_CERTIFICATE_PARSER
+	select ASN1_DECODER
+	select ASN1_COMPILER
+	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.
