Mark,

That’s not a fair point about closing issue #19.

Your main concern was that SHA-3 algorithms might not be easily available but, 
luckily, they shipped with TLS 1.3 in OpenSSL 1.1.1 and so I thought #19 was a 
solved issue.

Regardless, sooner or later, someone will be the first to use a SHA-3 algorithm 
that’s better than the SHA-2 algorithms DNS uses today. It’s only a matter of 
time. SHA-3 has been out since 2015. As soon as you support TLS 1.3, you’ll 
have all the SHA-3 algorithms with a simple API call and it should be available 
everywhere because TLS 1.3 will be needed everywhere.

I will reopen this issue for discussion but I don’t see yet how this is a 
problem.

Thanks,
Tom
