Good tutorial, thanks for the sharing! Hashing is indeed an important proces.

Anyway I just wanted to say I'm currently developing a program to check all the Windows files for Hashes and if anything changed. A sort of tripwire actually. I will be re-creating it for Linux as well. As this is written in .NET, but it will be re-written in pyhton.

It's not finished yet, but I will release it here.

Rkhunter does this technically. It takes the SHA-1 sum of files and matches them to known good ones in an online database. You could possibly make it list all of the files on the system and compare them to a local database.
