If 62 it is, the PKCS#7 wrapper is discarded and reading the key returns 63 just the payload. If it isn't, adding the key will fail with an 64 error. 65 66 This is intended for testing the PKCS#7 parser. 67 68 config SIGNED_PE_FILE_VERIFICATION 69 bool "Support for PE file signature verification" 70 depends on PKCS7_MESSAGE_PARSER=y 71 depends on SYSTEM_DATA_VERIFICATION 72 select CRYPTO_HASH 73 select ASN1 74 select OID_REGISTRY 75 help 76 This option provides support for verifying the signature(s) on a 77 signed PE binary. 78 79 config FIPS_SIGNATURE_SELFTEST 80 tristate "Run FIPS selftests on the X.509+PKCS7 signature verification" 81 help 82 This option causes some selftests to be run on the signature 83 verification code, using some built in data.
