Method Detail

getPassword

char[] getPassword(AuthenticationRequestType type)
            throws PSQLException

Callback method to provide the password to use for authentication.

Implementers can also check the authentication type to ensure that the authentication handshake is using a specific authentication method (e.g. SASL) or avoiding a specific one (e.g. cleartext).

For security reasons, the driver will wipe the contents of the array returned by this method after it has been used for authentication.

Implementers must provide a new array each time this method is invoked as the previous contents will have been wiped.

Parameters:

type - The authentication method that the server is requesting

Returns:

The password to use or null if no password is available

Throws:

PSQLException - if something goes wrong supplying the password
