We basically bruteforced this one. We knew that the letters that formed the key were : 3,D,R,W,3,I,C,{,}
we could get rid of the two brackets and IW, so we're left with 3,D,R,3, and C.
we tried inputing every combination of the 5 characters into the ctf page, and it eventually worked, with:
IW{3DRC3}
