# ARC4 Cracking Competition Submission
- 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.
