Method Detail

getPassword

public static java.lang.String getPassword(AuthenticationRequestType type,
                                           java.util.Properties info)
                                    throws PSQLException

If a password is requested by the server during connection initiation, this method will be invoked to supply the password. This method will only be invoked if the server actually requests a password, e.g. trust authentication will skip it entirely.

Parameters:

type - The authentication type that is being requested

info - The connection properties for the connection

Returns:

The password to use for authentication or null if none is available

Throws:

PSQLException - Throws a PSQLException if the plugin class cannot be instantiated

getEncodedPassword

public static byte[] getEncodedPassword(AuthenticationRequestType type,
                                        java.util.Properties info)
                                 throws PSQLException

Helper that wraps getPassword(...), checks that it is not-null, and encodes it as a byte array. Used by internal code paths that require an encoded password that may be an empty string, but not null.

Parameters:

type - The authentication type that is being requested

info - The connection properties for the connection

Returns:

The password to use for authentication encoded as a byte array

Throws:

PSQLException - Throws a PSQLException if the plugin class cannot be instantiated or if the retrieved password is null.
