patented vs secret (was Re: RC4)

By the way, since RSA is such a vocal opponent of the Clipper chip on the grounds of its secret Skipjack algorithm, why does it market secret algorithms like RC4 and RC2? Does this seen like a double face to anyone else?

Patented does not equal secret. The argument against Clipper (at least one of them ;-), is that it has not been subjected to review outside of the NSA. I believe the code for RC4 and RC2 is accessible and has been subjected to review by many in the crypto field - you just can't use it legally without a license. Noam
