KEYS: Provide a script to extract a module signature
The supplied script takes a signed module file and extracts the tailmost signature (there could theoretically be more than one) and dumps all or part of it or the unsigned file to stdout. Call as: scripts/extract-module-sig.pl -[0adnks] module-file >out where the initial flag indicates which bit of the signed file you want dumping to stdout: (*) "-0". Dumps the unsigned data with the signature stripped. (*) "-a". Dumps all of the signature data, including the magic number. (*) "-d". Dumps the signature information block as a sequence of decimal numbers in text form with spaces between (crypto algorithm type, hash type, identifier type, signer's name length, key identifier length and signature length). (*) "-n". Dumps the signer's name contents. (*) "-k". Dumps the key identifier contents. (*) "-s". Dumps the cryptographic signature contents. In the case that the signature is a PKCS#7 (or CMS) message,...
