-// arc4.cpp - written and placed in the public domain by Wei Dai

-// The ARC4 algorithm was first revealed in an anonymous email to the
-// cypherpunks mailing list. This file originally contained some
-// code copied from this email. The code has since been rewritten in order
-// to clarify the copyright status of this file. It should now be
-// completely in the public domain.
