</p>
<div></div>
<p dir="auto">The <code>NORMAL</code> priority keyword enables several protocols and algorithms
that shouldn't be considered secure by current standards,
specifically:</p>
<ul dir="auto">
<li>plain RSA key exchange</li>
<li>TLS 1.0</li>
<li>TLS 1.1</li>
<li>DTLS 1.0</li>
<li>SHA-1 signatures</li>
<li>SHA-1 MAC seems at least questionable</li>
</ul>
<p dir="auto">Aside from SHA-1 signatures and in some cases SHA-1 MAC this also
applies to all the <code>SECURE</code> variants, and everything aside from plain
RSA also to <code>PFS</code>.</p>
<p dir="auto">I suppose there may be a compatibility tradeoff regarding SHA-1 MAC,
but the rest could be removed without being any less compatible with
older servers than modern browsers. For TLS 1.2 servers that still
don't support AEAD adding SHA-256 MAC might be useful, whether SHA-1
is removed or not.</p>
<p dir="auto">Considering that these keywords are intended for people who want
reasonably secure defaults without digging into all the details I think they
should be updated soon. I'd be happy to prepare a patch if there is
consensus on what should be included.</p>
