7 help
8 Provide the file name of a private key/certificate in PEM format,
9 or a PKCS#11 URI according to RFC7512. The file should contain, or
10 the URI should identify, both the certificate and its corresponding
11 private key.
12
13 If this option is unchanged from its default "certs/signing_key.pem",
14 then the kernel will automatically generate the private key and
15 certificate as described in Documentation/module-signing.txt

19 depends on KEYS
20 help
21 Provide a system keyring to which trusted keys can be added. Keys in
22 the keyring are considered to be trusted. Keys may be added at will
23 by the kernel from compiled-in data and from hardware key stores, but
24 userspace may only add extra keys if those keys can be verified by
25 keys already in the keyring.
26
27 Keys in this keyring are used by module signature checking.

29config SYSTEM_TRUSTED_KEYS
30 string "Additional X.509 keys for default system keyring"
31 depends on SYSTEM_TRUSTED_KEYRING
32 help
33 If set, this option should be the filename of a PEM-formatted file
34 containing trusted X.509 certificates to be included in the default
35 system keyring. Any certificate used for module signing is implicitly
36 also trusted.
37
38 NOTE: If you previously provided keys for the system keyring in the
39 form of DER-encoded *.x509 files in the top-level build directory,
40 those are no longer used. You will need to set this option instead.
