Let’s talk about a very common mechanism to authenticate or verify a message or file: the ubiquitous MD5 algorithm. This four step process is described in RFC 1321 and they even provide some code examples. So, get your logic hat on and let’s cruise through another network or computer function.
Here are some additional computer and network math videos:
