RC4 Decrypt
===========
A brute-force RC4 stream cipher decryption circuit for FPGAs.
RC4 is a symmetric stream cipher common in internet protocols such as
SSL, WEP, and WPA. It has since been deem insecure due to multiple
vulnerabilities discovered.
This circuit runs 108 cracking cores in parallel with interleaved
key-space partitioning. The circuit assumes the decryption was
successful if the resulting output are all ASCII printable characters
(non control characters).
