Class DefaultCryptingDelegateFactory

java.lang.Object
rs.baselib.crypto.DefaultCryptingDelegateFactory
All Implemented Interfaces:
ICryptingDelegateFactory
public class DefaultCryptingDelegateFactory
extends java.lang.Object
implements ICryptingDelegateFactory
Creates a crypting delegator. This class finds its configuration via classpath. You can give java argument -Dencryption.config=path which will then load the config from this path. The default location is encryption-config.xml.
