Custom SSLSocketFactory

PostgreSQL provides a way for developers to customize how a SSL connection is established. This may be used to provide a custom certificate source or other extensions by allowing the developer to create their own SSLContext instance. The connection URL parameters sslfactory allow the user to specify which custom class to use for creating the SSLSocketFactory . The class name specified by sslfactory must extend `` and be available to the driver’s classloader.

This class must have a zero argument constructor or a single argument constructor preferentially taking a Properties argument. There is a simple org.postgresql.ssl.DefaultJavaSSLFactory provided which uses the default java SSLFactory.

Information on how to actually implement such a class is beyond the scope of this documentation. Places to look for help are the JSSE Reference Guide and the source to the NonValidatingFactory provided by the JDBC driver.
