Hi John,

that is great to hear. Our two interests are PQC algorithms for TLS in
Firefox and S/MIME in Thunderbird. As I understand it you are working on
the former. Hash-based signatures are also interesting for us, mainly
stateless ones. Are you going to support SPHINCS+ certificates for TLS, too?

Will there also be a publicly available version of Firefox with PQC support?

And do you already have a decision or idea about the (temporary)
certificate standard you are going to follow? If we could agree on a set of
algorithms and the preliminary certificate format, that would be ideal.
