wheeeee Crypto (375 pts) ---------------- Although it seems like The Plague's messaging service is secure, there are bound to be bugs in any 20th century crypto system. We've recovered a version of the block cipher The Plague implemented. Use their online encryptor tool, at 18.104.22.168:8193, to break the cipher and figure out Plague's secret plans. NOTE: When the service sends you a hex-encoded string, respond with a hex-encoded string.
Although it seems like The Plague's projects are open source, it's not quite so simple to figure out what the source code does. We believe this project is supposed to print out secret information, but the KEY variable in the Makefile has been lost. Find the key, build the project, get us the information.
Oh noes, the key is gone!
The Plague is running a betting service to build up funds for his massive empire. Can you figure out a way to beat the house? The service is running at 22.214.171.124:4321.
