validation - OS X shell: how to validate kexts signature? -

i'd shell script verify if /system/library/extensions folder (and subfolders) contains kexts don't pass signature validation. how do that?

there couple utilities seem include kind of functionality, e.g.

kextcache -system-prelinked-kernel

but either apply modifications scheme or other unwanted lenghty checks. signature validation necessary here. many in advance help!
