## Class SslRMIClientSocketFactory

- java.lang.Object
- - javax.rmi.ssl.SslRMIClientSocketFactory

- All Implemented Interfaces:
    Serializable, RMIClientSocketFactory

      public class SslRMIClientSocketFactory
      extends Object
      implements RMIClientSocketFactory, Serializable

  An `SslRMIClientSocketFactory` instance is used by the RMI runtime in order to obtain client sockets for RMI calls via SSL.

  This class implements `RMIClientSocketFactory` over the Secure Sockets Layer (SSL) or Transport Layer Security (TLS) protocols.

  This class creates SSL sockets using the default `SSLSocketFactory` (see `SSLSocketFactory.getDefault()`). All instances of this class are functionally equivalent. In particular, they all share the same truststore, and the same keystore when client authentication is required by the server. This behavior can be modified in subclasses by overriding the `createSocket(String,int)` method; in that case, `equals` and `hashCode` may also need to be overridden.

  If the system property `javax.rmi.ssl.client.enabledCipherSuites` is specified, the `createSocket(String,int)` method will call `SSLSocket.setEnabledCipherSuites(String[])` before returning the socket. The value of this system property is a string that is a comma-separated list of SSL/TLS cipher suites to enable.

  If the system property `javax.rmi.ssl.client.enabledProtocols` is specified, the `createSocket(String,int)` method will call `SSLSocket.setEnabledProtocols(String[])` before returning the socket. The value of this system property is a string that is a comma-separated list of SSL/TLS protocol versions to enable.

- - ### Constructor Detail

    - #### SslRMIClientSocketFactory

          public SslRMIClientSocketFactory()

      Creates a new `SslRMIClientSocketFactory`.

  - ### Method Detail

    - #### createSocket

          public Socket createSocket(String host,
                                     int port)
                              throws IOException

      Creates an SSL socket.

      If the system property `javax.rmi.ssl.client.enabledCipherSuites` is specified, this method will call `SSLSocket.setEnabledCipherSuites(String[])` before returning the socket. The value of this system property is a string that is a comma-separated list of SSL/TLS cipher suites to enable.

      If the system property `javax.rmi.ssl.client.enabledProtocols` is specified, this method will call `SSLSocket.setEnabledProtocols(String[])` before returning the socket. The value of this system property is a string that is a comma-separated list of SSL/TLS protocol versions to enable.

      Specified by:
        `createSocket` in interface `RMIClientSocketFactory`
      Parameters:
        `host` - the host name
        `port` - the port number
      Returns:
        a socket connected to the specified host and port.
      Throws:
        `IOException` - if an I/O error occurs during socket creation

    - #### equals

          public boolean equals(Object obj)

      Indicates whether some other object is "equal to" this one.

      Because all instances of this class are functionally equivalent (they all use the default `SSLSocketFactory`), this method simply returns `this.getClass().equals(obj.getClass())`.

      A subclass should override this method (as well as `hashCode()`) if its instances are not all functionally equivalent.

      Overrides:
        `equals` in class `Object`
      Parameters:
        `obj` - the reference object with which to compare.
      Returns:
        `true` if this object is the same as the obj argument; `false` otherwise.
      See Also:
        `Object.hashCode()`, `HashMap`

    - #### hashCode

          public int hashCode()

      Returns a hash code value for this `SslRMIClientSocketFactory`.

      Overrides:
        `hashCode` in class `Object`
      Returns:
        a hash code value for this `SslRMIClientSocketFactory`.
      See Also:
        `Object.equals(java.lang.Object)`, `System.identityHashCode(java.lang.Object)`
