 # ARC4 Cracking Competition Submission
 
-_Describe your strategy for fast ARC4 cracking._
-_Include the original crack time from lab 3 task 5, and the improved crack time of your bonus lab.If it isn't visible in the reports, include your board name (e.g. DE1 SoC, DE10 Lite, etc.)_
+- We implemented 108 ARC4 cracking cores in parallel.
+- This also required around 108 times the memory usage.
+- In the future, this can be improved by using two-port memory, or by not writing the plaintext until we confirm the key is valid.
+- A PLL was added for frequency synthesis using the 50 MHz clock signal. We used a conservative clock of 90 MHz with the PLL.
+- The cracking can also be pipelined further in the future.
