The idea of checking file integrity via hashing is good, the only thing I have against this thread is the use of MD5.

To anyone reading, I'd recommend SHA-1 hashing over MD5, considering MD5 has significantly greater room for collisions than SHA-1. As of October 15, 2015, there are no publicly known collisions for SHA-1. There have only been theoretical collisions.

All of this is true. See my response to Sans.

I'll make a follow up to this thread about why sha1 = more better
