Checking software: PGP, MD5 etc..
Ok, i've been meaning to ask this for quite some time now but i have not gotten around to it.
Here is my question:
Anytime you download software for Linux, there is also a corresponding PGP file, MD5 or some other file that is used to check to make sure the software you downloaded is correct.
I was wondering if someone can give me a crash course on how to do this and use the files correctly, or point me in the direction of a how-to of some sort.
