12 config ASYMMETRIC_PUBLIC_KEY_SUBTYPE
13 tristate "Asymmetric public-key crypto algorithm subtype"
15 select CRYPTO_HASH_INFO
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.
22 config X509_CERTIFICATE_PARSER
23 tristate "X.509 certificate parser"
24 depends on ASYMMETRIC_PUBLIC_KEY_SUBTYPE
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
38 This option provides support for parsing PKCS#7 format messages for
39 signature data and provides the ability to verify the signature.

44 select SYSTEM_TRUSTED_KEYRING
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
