This is another time @blackb6a unites and plays UIUCTF together. It was my fourth time playing UIUCTF, and I still found the challenges fun. Although the crypto challenges are relatively easy, I had a lot of fun solving phpfuck with @02E774.

nookcrypt is a netcat service that have no source code released. There are two functions exposed:

1. Gets an encrypted copy of the flag (and the message hello world).
2. Encrypts an arbitrary message.
