Hi,

Please guide on how to properly deploy Diffie-Hellman on my server. I am
using Jetty 9.2.9 with jdk1.7.



This is my current configuration in jetty-ssl.xml but SSL scan report shows
that “This server supports insecure Diffie-Hellman (DH) key exchange
parameters (Logjam)”



<Set name="ExcludeCipherSuites">

    <Array type="String">

      <Item>.*NULL.*</Item>

      <Item>.*RC4.*</Item>

      <Item>.*MD5.*</Item>

      <Item>.*DES.*</Item>

      <Item>.*DSS.*</Item>

    </Array>

  </Set>

 <!-- Enable Forward Secrecy Ciphers.       Note: this replaces the default
Include Cipher list -->

  <Set name="IncludeCipherSuites">

    <Array type="String">

      <Item>TLS_DHE_RSA.*</Item>

      <Item>TLS_ECDHE.*</Item>

    </Array>

  </Set>

<!-- Eliminate Insecure Protocols -->

  <Call name="addExcludeProtocols">

    <Arg>

     <Array type="java.lang.String">

       <Item>SSL</Item>

       <Item>SSLv2</Item>

       <Item>SSLv2Hello</Item>

       <Item>SSLv3</Item>

       <Item>TLSv1</Item>

       <Item>TLSv1.1</Item>

     </Array>

    </Arg>

  </Call>



Regards

Rjc
