## javax.rmi.ssl
Class SslRMIServerSocketFactory

    java.lang.Object
      javax.rmi.ssl.SslRMIServerSocketFactory

All Implemented Interfaces:
  RMIServerSocketFactory

    public class SslRMIServerSocketFactory

extends Object
implements RMIServerSocketFactory

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

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

This class creates SSL sockets using the default `SSLSocketFactory` (see `SSLSocketFactory.getDefault()`) or the default `SSLServerSocketFactory` (see `SSLServerSocketFactory.getDefault()`). Therefore, all instances of this class share the same keystore, and the same truststore, when client authentication is required by the server. This behavior can be modified in subclasses by overriding the `createServerSocket(int)` method; in that case, `equals` and `hashCode` may also need to be overridden.

Since:
  1.5
See Also:
  `SSLSocketFactory`, `SSLServerSocketFactory`, `SslRMIClientSocketFactory`

Constructor Summary
`SslRMIServerSocketFactory()` Creates a new `SslRMIServerSocketFactory` with the default SSL socket configuration.
`SslRMIServerSocketFactory(String[] enabledCipherSuites, String[] enabledProtocols, boolean needClientAuth)` Creates a new `SslRMIServerSocketFactory` with the specified SSL socket configuration.

Method Summary
`ServerSocket` | `createServerSocket(int port)` Creates a server socket that accepts SSL connections configured according to this factory's SSL socket configuration parameters.
`boolean` | `equals(Object obj)` Indicates whether some other object is "equal to" this one.
`String[]` | `getEnabledCipherSuites()` Returns the names of the cipher suites enabled on SSL connections accepted by server sockets created by this factory, or `null` if this factory uses the cipher suites that are enabled by default.
`String[]` | `getEnabledProtocols()` Returns the names of the protocol versions enabled on SSL connections accepted by server sockets created by this factory, or `null` if this factory uses the protocol versions that are enabled by default.
`boolean` | `getNeedClientAuth()` Returns `true` if client authentication is required on SSL connections accepted by server sockets created by this factory.
`int` | `hashCode()` Returns a hash code value for this `SslRMIServerSocketFactory`.

Constructor Detail

### SslRMIServerSocketFactory

    public SslRMIServerSocketFactory()

  Creates a new `SslRMIServerSocketFactory` with the default SSL socket configuration.

  SSL connections accepted by server sockets created by this factory have the default cipher suites and protocol versions enabled and do not require client authentication.

### SslRMIServerSocketFactory

    public SslRMIServerSocketFactory(String[] enabledCipherSuites,
                                     String[] enabledProtocols,
                                     boolean needClientAuth)
                              throws IllegalArgumentException

  Creates a new `SslRMIServerSocketFactory` with the specified SSL socket configuration.

  Parameters:
    `enabledCipherSuites` - names of all the cipher suites to enable on SSL connections accepted by server sockets created by this factory, or `null` to use the cipher suites that are enabled by default
    `enabledProtocols` - names of all the protocol versions to enable on SSL connections accepted by server sockets created by this factory, or `null` to use the protocol versions that are enabled by default
    `needClientAuth` - `true` to require client authentication on SSL connections accepted by server sockets created by this factory; `false` to not require client authentication
  Throws:
    `IllegalArgumentException` - when one or more of the cipher suites named by the `enabledCipherSuites` parameter is not supported, when one or more of the protocols named by the `enabledProtocols` parameter is not supported or when a problem is encountered while trying to check if the supplied cipher suites and protocols to be enabled are supported.
  See Also:
    `SSLSocket.setEnabledCipherSuites(java.lang.String[])`, `SSLSocket.setEnabledProtocols(java.lang.String[])`, `SSLSocket.setNeedClientAuth(boolean)`

Method Detail

### getEnabledCipherSuites

    public final String[] getEnabledCipherSuites()

  Returns the names of the cipher suites enabled on SSL connections accepted by server sockets created by this factory, or `null` if this factory uses the cipher suites that are enabled by default.

  Returns:
    an array of cipher suites enabled, or `null`
  See Also:
    `SSLSocket.setEnabledCipherSuites(java.lang.String[])`

### getEnabledProtocols

    public final String[] getEnabledProtocols()

  Returns the names of the protocol versions enabled on SSL connections accepted by server sockets created by this factory, or `null` if this factory uses the protocol versions that are enabled by default.

  Returns:
    an array of protocol versions enabled, or `null`
  See Also:
    `SSLSocket.setEnabledProtocols(java.lang.String[])`

### getNeedClientAuth

    public final boolean getNeedClientAuth()

  Returns `true` if client authentication is required on SSL connections accepted by server sockets created by this factory.

  Returns:
    `true` if client authentication is required
  See Also:
    `SSLSocket.setNeedClientAuth(boolean)`

### createServerSocket

    public ServerSocket createServerSocket(int port)
                                    throws IOException

  Creates a server socket that accepts SSL connections configured according to this factory's SSL socket configuration parameters.

  Specified by:
    `createServerSocket` in interface `RMIServerSocketFactory`
  Parameters:
    `port` - the port number
  Returns:
    the server socket on the specified port
  Throws:
    `IOException` - if an I/O error occurs during server socket creation

### equals

    public boolean equals(Object obj)

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

  Two `SslRMIServerSocketFactory` objects are equal if they have been constructed with the same SSL socket configuration parameters.

  A subclass should override this method (as well as `hashCode()`) if it adds instance state that affects equality.

  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()`, `Hashtable`

### hashCode

    public int hashCode()

  Returns a hash code value for this `SslRMIServerSocketFactory`.

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