Introduction

Jetty has two SSL connectors–the SslSocketConnector and the SslSelectChannelConnector. The SslSocketConnector is built on top of the Jetty SocketConnector which is Jetty's implementation of a blocking connector. It uses Java's SslSocket to add the security layer. The SslSelectChannelConnector is an extension of Jetty's SelectChannelConnector which uses non-blocking IO. For its security layer, it uses java nio SslEngine. You can configure these two connectors similarly; the difference is in the implementation.

Configuring Jetty for SSL

Beginning with Jetty 7.3.1, the preferred way to configure SSL parameters for the connector is by configuring the SslContextFactory object and passing it to the connector's constructor.

The following is an example of an SslSelectChannelConnector configuration. You can configure an SslSocketConnector the same way–just change the value of the class to org.eclipse.jetty.server.ssl.SslSocketConnector.

   <Call name="addConnector">
     <Arg>
       <New class="org.eclipse.jetty.server.ssl.SslSelectChannelConnector">
         <Arg>
           <New class="org.eclipse.jetty.http.ssl.SslContextFactory">
             <Set name="port">8443</Set>
             <Set name="keyStore"><SystemProperty name="jetty.home" default="." />/etc/keystore</Set>
             <Set name="keyStorePassword">OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4</Set>
             <Set name="keyManagerPassword">OBF:1u2u1wml1z7s1z7a1wnl1u2g</Set>
             <Set name="trustStore"><SystemProperty name="jetty.home" default="." />/etc/keystore</Set>
             <Set name="trustStorePassword">OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4</Set>
           </New>
         </Arg
         <Set name="maxIdleTime">30000</Set>
       </New>
     </Arg>
   </Call>

Other properties that you can set for the SslContextFactory include:

• certAlias–Alias of a certificate to use.
• keyStoreType–Default value: "JKS."
• keyStoreProvider–Default is the SunJSSE provider.
• trustStoreType–Default value: "JKS".
• trustStoreProvider–Default is the SunJSSE provider.
• sslKeyManagerFactoryAlgorithm–Set to the value of the "ssl.KeyManagerFactory.algorithm" system property. If there is no such property, the default is "SunX509."
• sslTrustManagerFactoryAlgorithm–set to the value of the "ssl.TrustManagerFactory.algorithm" system property. If there is no such property, the default is "SunX509."
• secureRandomAlgorithm–Default value is null.
• protocol–Default value is "TLS."
• provider–Default is the first provider that supports that protocol.
• includeCipherSuites–See How to configure SSL Cipher Suites.
• excludeCipherSuites–See How to configure SSL Cipher Suites.
• needClientAuth–Default is false
• wantClientAuth–Defaults is false.
• validateCerts–Default is false.
• allowRenegotiate–Default is false.
• crlPath–Path to certificate revocation list file for SSL certificate validation.
• maxCertPathLengh–Maximum allowed number of intermediate certificates, default is -1 (unlimited).

If there is no value for the truststore, the system uses the keystore value. You can obfuscate passwords by using the Jetty password utility.

Using Deprecated Methods

The methods of SslConnector that Jetty previously used to configure SSL parameters have been deprecated and will be removed in a future version of Jetty. An example of configuring SslSelectChannelConnector connector in Jetty 7.3.0 and earlier follows.

   <Call name="addConnector">
     <Arg>
       <New class="org.eclipse.jetty.server.ssl.SslSelectChannelConnector">
         <Set name="Port">8443</Set>
         <Set name="maxIdleTime">30000</Set>
         <Set name="keystore"><SystemProperty name="jetty.home" default="." />/etc/keystore</Set>
         <Set name="password">OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4</Set>
         <Set name="keyPassword">OBF:1u2u1wml1z7s1z7a1wnl1u2g</Set>
         <Set name="truststore"><SystemProperty name="jetty.home" default="." />/etc/keystore</Set>
         <Set name="trustPassword">OBF:1vny1zlo1x8e1vnw1vn61x8g1zlu1vn4</Set>
       </New>
     </Arg>
   </Call>
