Check package component checksums against a database?

[Mirsad Todorovac <mtodorov@alu.hr>]

Hi, everybody!

I wondered if there is a way to check apt-get package maintained system 
against a database of known checksums. This could be md5 checksum or 
timestamp, size and BSD checksum of programs).

I know there is AIDE, but it has the weakness of locally maintained 
database of checksums that intruder can defeat once boarded the system.

Any idea how to do this, without reinstalling the Debian system from 
scratch?

Thanks,
Marvin
