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
The connection URL parameters
sslfactory allow the user to specify which custom
class to use for creating the
SSLSocketFactory. The class name specified by
javax.net.ssl.SSLSocketFactory and be available to the driver's classloader.
This class must have a zero argument constructor or a single argument constructor preferentially taking
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.
