-    This code is derived from section 17.1 of Applied Cryptography,
-    second edition, which describes a stream cipher allegedly
-    compatible with RSA Labs "RC4" cipher (the actual description of
-    which is a trade secret).  The same algorithm is used as a stream
-    cipher called "arcfour" in Tatu Ylonen's ssh package.
-
-    Here the stream cipher has been modified always to include the time
-    when initializing the state.  That makes it impossible to
-    regenerate the same random sequence twice, so this can't be used
-    for encryption, but will generate good random numbers.
-
-    RC4 is a registered trademark of RSA Laboratories.
