In this case, I'm not sure.  RC4 is probably still considered a trade
secret by RSA (the company), and I don't think you can easily claim
that your code implements RC4.

Of course, in the meantime, RSA indirectly admitted that the code
which was posted to Usenet a couple of years ago.  Recently, Papers
started talking about "the RC4 algorithm" instead of "the alleged RC4
algorithm", but I don't think much has changed, at least formally.
