Yup.  We would have been better off if they'd stuck to 40 bit crypto in
1994 and covered 100% of the web.  It's relatively easy to upgrade from
40 bit to 128 bit.  It's a real pig to upgrade from 0 bit to 40 bit.

But you can't tell a standards group or a committee or a cypherpunk or a
vendor or any other cartel things like that.

Imagine going to PKIX and saying "oh, RC4 is fine, but can you make SSL
opportunistic and phase out HTTP in favour of HTTPS, please?  Pretty


ps; I agree with replacing RC4 wherever it is seen.  It's where it is
not seen I get upset about.
