13 tristate "Asymmetric public-key crypto algorithm subtype"
15 select PUBLIC_KEY_ALGO_RSA
16 select CRYPTO_HASH_INFO
18 This option provides support for asymmetric public key type handling.
19 If signature generation and/or verification are to be used,
20 appropriate hash algorithms (such as SHA-1) must be available.
21 ENOPKG will be reported if the requisite algorithm is unavailable.
23 config PUBLIC_KEY_ALGO_RSA
24 tristate "RSA public-key algorithm"
27 This option enables support for the RSA algorithm (PKCS#1, RFC3447).
29 config X509_CERTIFICATE_PARSER
30 tristate "X.509 certificate parser"
31 depends on ASYMMETRIC_PUBLIC_KEY_SUBTYPE
35 This option provides support for parsing X.509 format blobs for key
36 data and provides the ability to instantiate a crypto key from a
37 public key packet found inside the certificate.
39 config PKCS7_MESSAGE_PARSER
40 tristate "PKCS#7 message parser"
41 depends on X509_CERTIFICATE_PARSER
45 This option provides support for parsing PKCS#7 format messages for
46 signature data and provides the ability to verify the signature.

50 depends on PKCS7_MESSAGE_PARSER
51 select SYSTEM_TRUSTED_KEYRING
53 This option provides a type of key that can be loaded up from a
54 PKCS#7 message - provided the message is signed by a trusted key. If
55 it is, the PKCS#7 wrapper is discarded and reading the key returns
56 just the payload. If it isn't, adding the key will fail with an
