Don't bother. It's unlikely to be used in a browser. This just underscores the point I was making that people use TLS differently for different things and the requirements are not the same. Just as it doesn't make sense to force a browser to implement a PSK (or PAKE) cipher suite, it doesn't make sense to force some device with a limited UI that has no interest in accessing random web servers to use a public key. regards, Dan. _______________________________________________ TLS mailing list TLS@ietf.org https://www.ietf.org/mailman/listinfo/tls
