+/**
+ * RC4 is a stream cipher developed by Ron Rivest. Until 1994 RC4 was a trade
+ * secret of RSA Data Security, Inc., when it was released anonymously to a
+ * mailing list. This version is a descendent of that code, and since there is
+ * no proof that the leaked version was in fact RC4 and because "RC4" is a
+ * trademark, it is called "ARCFOUR", short for "Allegedly RC4".
+ * <p>
+ * This class only implements the <i>keystream</i> of ARCFOUR. To use this as a
+ * stream cipher, one would say:
+ * <pre>
+ * out = in &circ; arcfour.nextByte();
+ * </pre>
+ * <p>
+ * This operation works for encryption and decryption.
