Hash values, checksums and original integrity












0















I've been searching about integrity checking, found many tools, the powershell method etc. However I have a question that I guess comes from theoretical lack of knowledge.



Even if I check the hash of a file, how can I know that this is the origibnal one? Shouldn;t be an online list for MS apps at least hash values so I can compare them?



Please enlighten me. I'm about to write a win security monitoring tool and I want to integrate hash checking into it.



Thanks
