Comment (by dgoulet):

 The goal is really to avoid generating a key, not writing it on disk and
 using it after assuming somehow it has been saved. Sounds like generating
 and writing a key to disk is a "critical path" that must be confirmed
 either right away and/or regularly after?

 So yes, makes total sense to me to be very thorough about validating key
 in memory with one on disk.
