+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).
