com.sun.org.apache.xml.internal.security.keys.KeyInfo
This class stand for KeyInfo Element that may contain keys, names, certificates and other public key management information, such as in-band key distribution or key agreement data.
KeyInfo Element has two basic functions: One is KeyResolve for getting the public key in signature validation processing. the other one is toElement for getting the element in signature generation processing.
The lengthXXX() methods provide access to the internal Key objects:
- If the KeyInfo was constructed from an Element (Signature verification), the lengthXXX() methods searches for child elements of ds:KeyInfo for known types.
- If the KeyInfo was constructed from scratch (during Signature generation), the lengthXXX() methods return the number of XXXs objects already passed to the KeyInfo
The addXXX() methods are used for adding Objects of the appropriate type to the KeyInfo. This is used during signature generation.
The itemXXX(int i) methods return the i'th object of the corresponding type.
The containsXXX() methods return whether the KeyInfo contains the corresponding type. @author $Author: raul $
