Be careful; that's misleading. Some of us believe that RC4 is in the
public domain, but RSADSI still maintains that it is proprietary. RC5 and
RC6 are patented, and definitely not in the public domain. RC2 is heading
towards the public domain, but I do not believe it is there yet. There is
no such thing as RC1 and RC3 (at least in public).
