This project simulates a heartbleed cyberattack, a cyberattack where the hacker tricks the server into giving them as much data as they want (that is on the server or can be requested by the server). It's been patched out across most of the internet, so don't try it on a real server! Give the server a word, then give the server the number of letters in that word. Try giving the server more letters than are in that word!
The idea for this project was sparked by https://xkcd.com/1353/.
