Lets say we have this package: callforwarding_1.0-1_armel.deb

inside the package there's the control folder, and inside it there is "md5sums" which contains paths for various stuff afaik. For example:

8fbde587a6965bbaf5e8e301a4d80589 usr/share/locale/en_GB/LC_MESSAGES/callforwarding.mo

Now my question is where did this "8fbde587a6965bbaf5e8e301a4d80589" come from?

Silly question yep, but i want to know
