pefile: Parse a PE binary to find a key and a signature contained therein Parse a PE binary to find a key and a signature contained therein. Later patches will check the signature and add the key if the signature checks out.

pefile: Parse the "Microsoft individual code signing" data blob The PKCS#7 certificate should contain a "Microsoft individual code signing" data blob as its signed content. This blob contains a digest of the signed content of the PE binary and the OID of the digest algorithm used (typically SHA256).

KEYS: Generalise system_verify_data() to provide access to internal content Generalise system_verify_data() to provide access to internal content through a callback. This allows all the PKCS#7 stuff to be hidden inside this function and removed from the PE file parser and the PKCS#7 test key. If external content is not required, NULL should be passed as data to the function. If the callback is not required, that can be set to NULL. The function is now called verify_pkcs7_signature() to contrast with verify_pefile_signature() and the definitions of both have been moved into linux/verification.h along with the key_being_used_for enum.
