<p dir="auto">My previous MR (<a href="https://gitlab.com/gnutls/gnutls/-/merge_requests/1221" data-original="!1221" data-link="false" data-link-reference="false" data-project="179611" data-merge-request="53257396" data-project-path="gnutls/gnutls" data-iid="1221" data-mr-title="improve gnutls-cli-debug testing of old SSL 3.0 servers" data-reference-type="merge_request" data-container="body" data-placement="top" data-html="true" title="" class="gfm gfm-merge_request">!1221</a>) could be improved, because it correctly shows the (partial) SSL 3.0 support of these servers but does not show the (partial) TLS 1.0 support.</p>

<p dir="auto">With <a href="https://gitlab.com/gnutls/gnutls/-/merge_requests/1251" data-original="!1251" data-link="false" data-link-reference="false" data-project="179611" data-merge-request="58899736" data-project-path="gnutls/gnutls" data-iid="1251" data-mr-title="refine tests for ancient servers which support both SSL 3.0 and TLS 1.0, but both only with %NO_EXTENSIONS" data-reference-type="merge_request" data-container="body" data-placement="top" data-html="true" title="" class="gfm gfm-merge_request">!1251</a>, this is improved, and a few other important bits of the output are clarified:</p>
<pre class="code highlight js-syntax-highlight plaintext" lang="plaintext" v-pre="true"><code><span id="LC1" class="line" lang="plaintext"> whether we need to disable TLS 1.0... no</span>
<span id="LC2" class="line" lang="plaintext"> whether %NO_EXTENSIONS is required... yes</span>
<span id="LC3" class="line" lang="plaintext"> for 3DES-CBC cipher (RFC2246) support... yes</span>
<span id="LC4" class="line" lang="plaintext"> for ARCFOUR 128 cipher (RFC2246) support... yes</span></code></pre>
<p dir="auto">This clarifying information may enable someone who needs to use such a server to use the
(marginally-less insecure?) combination of TLS 1.0 and RC4 rather than SSL 3.0.</p>
