The Rivest Cypher 4 is a stream cipher algorithm developed in the 1980s, remarkable for its fast implementations in both hardware and software.The RC4 algorithm outputs a pseudo random stream of bytes based on a n-byte long key. The key can be any length, but is usually longer than 6 bytes. The bitstream is deterministic, as a key will always produce the same bitstream.

The counter design (gdsii file) is located at here and the wrappered counter (gdsii file) is located at here.
