menuconfig ASYMMETRIC_KEY_TYPE
bool "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 CRYPTO_HASH_INFO
select CRYPTO_AKCIPHER
select CRYPTO_HASH
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 ASYMMETRIC_TPM_KEY_SUBTYPE
tristate "Asymmetric TPM backed private key subtype"
depends on TCG_TPM
depends on TRUSTED_KEYS
select CRYPTO_HMAC
select CRYPTO_SHA1
select CRYPTO_HASH_INFO
help
This option provides support for TPM backed private key type handling.
Operations such as sign, verify, encrypt, decrypt are performed by
the TPM after the private key is loaded.
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 PKCS8_PRIVATE_KEY_PARSER
tristate "PKCS#8 private key parser"
depends on ASYMMETRIC_PUBLIC_KEY_SUBTYPE
select ASN1
select OID_REGISTRY
help
This option provides support for parsing PKCS#8 format blobs for
private key data and provides the ability to instantiate a crypto key
from that data.
config TPM_KEY_PARSER
tristate "TPM private key parser"
depends on ASYMMETRIC_TPM_KEY_SUBTYPE
select ASN1
help
This option provides support for parsing TPM format blobs for
private key data and provides the ability to instantiate a crypto key
from that data.
config PKCS7_MESSAGE_PARSER
tristate "PKCS#7 message parser"
depends on X509_CERTIFICATE_PARSER
select CRYPTO_HASH
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 SYSTEM_DATA_VERIFICATION
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
depends on SYSTEM_DATA_VERIFICATION
select CRYPTO_HASH
select ASN1
select OID_REGISTRY
help
This option provides support for verifying the signature(s) on a
signed PE binary.
