## Class JSSESupport

- java.lang.Object
- - org.apache.tomcat.util.net.jsse.JSSESupport

- All Implemented Interfaces:
    SSLSessionManager, SSLSupport

      public class JSSESupport
      extends Object
      implements SSLSupport, SSLSessionManager

  JSSESupport Concrete implementation class for JSSE Support classes. This will only work with JDK 1.2 and up since it depends on JDK 1.2's certificate support

    - #### JSSESupport

          @Deprecated
          public JSSESupport(SSLSession session)

      Deprecated. This will be removed in Tomcat 10.1.x onwards Use `JSSESupport(SSLSession, Map)`
      Parameters:
        `session` - SSLSession from which information is to be extracted

    - #### JSSESupport

          public JSSESupport(SSLSession session,
                     Map<String,List<String>> additionalAttributes)

  - ### Method Detail

    - #### getCipherSuite

          public String getCipherSuite()
                                throws IOException

      Description copied from interface: `SSLSupport`
      The cipher suite being used on this connection.
      Specified by:
        `getCipherSuite` in interface `SSLSupport`
      Returns:
        The name of the cipher suite as returned by the SSL/TLS implementation
      Throws:
        `IOException` - If an error occurs trying to obtain the cipher suite

    - #### getPeerCertificateChain

          public X509Certificate[] getPeerCertificateChain()
                                                    throws IOException

      Description copied from interface: `SSLSupport`
      The client certificate chain (if any).
      Specified by:
        `getPeerCertificateChain` in interface `SSLSupport`
      Returns:
        The certificate chain presented by the client with the peer's certificate first, followed by those of any certificate authorities
      Throws:
        `IOException` - If an error occurs trying to obtain the certificate chain

    - #### getKeySize

          public Integer getKeySize()
                             throws IOException

      Get the keysize. What we're supposed to put here is ill-defined by the Servlet spec (S 4.7 again). There are at least 4 potential values that might go here: (a) The size of the encryption key (b) The size of the MAC key (c) The size of the key-exchange key (d) The size of the signature key used by the server Unfortunately, all of these values are nonsensical.

      This returns the effective bits for the current cipher suite.

      Specified by:
        `getKeySize` in interface `SSLSupport`
      Returns:
        The effective key size for the current cipher suite
      Throws:
        `IOException` - If an error occurs trying to obtain the key size

    - #### getSessionId

          public String getSessionId()
                              throws IOException

      Description copied from interface: `SSLSupport`
      The current session Id.
      Specified by:
        `getSessionId` in interface `SSLSupport`
      Returns:
        The current SSL/TLS session ID
      Throws:
        `IOException` - If an error occurs trying to obtain the session ID

    - #### setSession

          public void setSession(SSLSession session)

    - #### invalidateSession

          public void invalidateSession()

      Invalidate the session this support object is associated with.
      Specified by:
        `invalidateSession` in interface `SSLSessionManager`

    - #### getProtocol

          public String getProtocol()
                             throws IOException

      Specified by:
        `getProtocol` in interface `SSLSupport`
      Returns:
        the protocol String indicating how the SSL socket was created e.g. TLSv1 or TLSv1.2 etc.
      Throws:
        `IOException` - If an error occurs trying to obtain the protocol information from the socket

    - #### getRequestedProtocols

          public String getRequestedProtocols()
                                       throws IOException

      Specified by:
        `getRequestedProtocols` in interface `SSLSupport`
      Returns:
        the list of SSL/TLS protocol versions requested by the client
      Throws:
        `IOException` - If an error occurs trying to obtain the client requested protocol information from the socket

    - #### getRequestedCiphers

          public String getRequestedCiphers()
                                     throws IOException

      Specified by:
        `getRequestedCiphers` in interface `SSLSupport`
      Returns:
        the list of SSL/TLS ciphers requested by the client
      Throws:
        `IOException` - If an error occurs trying to obtain the client request cipher information from the socket
