menuconfig ASYMMETRIC_KEY_TYPE
tristate "Asymmetric (public-key cryptographic) key type"
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.
if ASYMMETRIC_KEY_TYPE
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 CRYPTO_RSA
help
This option enables support for the RSA algorithm (PKCS#1, RFC3447).
config X509_CERTIFICATE_PARSER
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.
