      <title>API on TLS 1.2</title>

      <description>&lt;P&gt;For API, is DropBox going to be TLS 1.2 compliant?&amp;nbsp; On June 20, 2018, early versions of SSL/TLS will no longer be PCI compliant.&amp;nbsp;I was testing the Dropbox API on a TLS 1.2 only server and get the error below.&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&lt;A href="https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings" target="_blank"&gt;https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings&lt;/A&gt;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;System.ComponentModel.Win32Exception:&lt;BR /&gt;The client and server cannot communicate, because they do not possess a common algorithm at System.Net.SSPIWrapper.AcquireCredentialsHandle (SSPIInterface SecModule, String package, CredentialUse intent, SecureCredential scc)&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;&lt;P&gt;&amp;nbsp;&lt;/P&gt;</description>

      <description>&lt;P&gt;The&amp;nbsp;Dropbox API servers do support TLS 1.2, and it seems to be working correctly for me:&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;PRE&gt;$ curl --tlsv1.2 -v -X POST "https://api.dropboxapi.com/2/sharing/create_shared_link_with_settings"
*   Trying 162.125.1.7...
* TCP_NODELAY set
* Connected to api.dropboxapi.com (162.125.1.7) port 443 (#0)
* TLS 1.2 connection using TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
* Server certificate: api.dropboxapi.com
* Server certificate: DigiCert SHA2 High Assurance Server CA
* Server certificate: DigiCert High Assurance EV Root CA
&amp;gt; POST /2/sharing/create_shared_link_with_settings HTTP/1.1
&amp;gt; Host: api.dropboxapi.com
&amp;gt; User-Agent: curl/7.58.0
&amp;gt; Accept: */*
&amp;gt;
&amp;lt; HTTP/1.1 (remainder redacted for brevity)&lt;/PRE&gt;
&lt;P&gt;&lt;A href="https://www.ssllabs.com/ssltest/analyze.html?d=api.dropboxapi.com&amp;amp;s=162.125.3.7&amp;amp;latest" target="_self"&gt;An SSL Labs test confirms as much as well&lt;/A&gt;.&lt;/P&gt;
&lt;P&gt;&amp;nbsp;&lt;/P&gt;
&lt;P&gt;Based on the error output you shared, if you do have TLS 1.2 enabled, it looks like perhaps your client may not share any ciphers with the&amp;nbsp;Dropbox API servers. The above SSL Labs test page lists the supported ciphers. Please check your client configuration and enable ciphers as necessary.&lt;/P&gt;</description>
