The test harness uses the verify_sig_setup.sh to generate the required key material for program signing. Generate key material for signing LSKEL some lskel programs and use xxd to convert the verification certificate into a C header file. Finally, update the main test runner to load this certificate into the session keyring via the add_key() syscall before executing any tests. Use the session keyring in the tests with signed programs.
