"shed light on" could be "clarify the", "illuminate the", "elucidate the".

Let me go through the text sentence by sentence. The first sentence starts with "For years, cryptographers and puzzle enthusiasts have been fascinated by mysterious codes and ciphers..." So "For years" might become Along time. "Cryptographers" could be Coders, and "puzzle enthusiasts" maybe fans.
