Yes, correct. The idea is to verify the authenticity of RPM headers, 
extract the file digests from them, and use those file digests as 
reference values for integrity checking of files accessed by user space 
processes.

If the calculated digest of a file being accessed matches one extracted 
from the RPM header, access is granted otherwise it is denied.
