org.pentaho.di.core.encryption.KettleTwoWayPasswordEncoder

All Implemented Interfaces:

TwoWayPasswordEncoderInterface

public class KettleTwoWayPasswordEncoder
extends Object
implements TwoWayPasswordEncoderInterface

This class handles basic encryption of passwords in Kettle. Note that it's not really encryption, it's more obfuscation. Passwords are difficult to read, not impossible.
