Bunch of numbers with some letters up to F? Should be hex:
"code:3564, submit"
The final piece can be decoded using the same process to "submit-code".
Middle piece can be decoded to hex: "0746F3A2068747470733A2F2F7873746563682E65752F" but I didn't get past this because this hex gives me a binary that I could not make sense of.
