KeyValue

public class KeyValue extends SignatureElementProxy implements KeyInfoContent
The KeyValue element contains a single public key that may be useful in validating the signature. Structured formats for defining DSA (REQUIRED) and RSA (RECOMMENDED) public keys are defined in Signature Algorithms (section 6.4). The KeyValue element may include externally defined public keys values represented as PCDATA or element types from an external namespace.
