A Ddigsig.rst19 Digital signature verification API provides a method to verify digital signature.
22 Digital signature verification is implemented using cut-down kernel port of
27 Public key and signature consist of header and MPIs::
38 uint8_t version; /* signature format version */
39 time_t timestamp; /* signature made */
48 Signature header is used as an input to generate a signature.
58 digsig_verify() - digital signature verification with public key
62 * digsig_verify() - digital signature verification with public key
64 * @sig: digital signature
65 * @sigen: length of the signature

A Dmodule-signing.rst22 installation and then checks the signature upon loading the module. This
26 signature checking is done by the kernel so that it is not necessary to have
34 SHA-512 (the algorithm is selected by data in the signature).
45 CONFIG_MODULE_SIG "Module signature verification"
53 signature for which the key is not known or a module that is unsigned.
61 signature that can be verified by a public key in the kernel's possession
242 signature is present but it does not confirm that the signature is valid!
244 Signed modules are BRITTLE as the signature is outside of the defined ELF
256 done in userspace. The signature checking is all done within the kernel.
267 a signature mismatch will not be permitted to load.
