abstract public class: KeySelector [javadoc | source]

java.lang.Object
   javax.xml.crypto.KeySelector

Direct Known Subclasses:
    SingletonKeySelector

A selector that finds and returns a key using the data contained in a KeyInfo object. An example of an implementation of this class is one that searchs a java.security.KeyStore for trusted keys that match information contained in a KeyInfo.

Whether or not the returned key is trusted and the mechanisms used to determine that is implementation-specific.
