Objects of this class represent an Encryption Target that can be part of
the FeatureBinding for an EncryptionPolicy (refer EncryptionPolicy.FeatureBinding).
Objects of this class act as KeyBindings for AuthenticationTokens such
as AuthenticationTokenPolicy.X509CertificateBinding and
AuthenticationTokenPolicy.SAMLAssertionBinding.
Objects of this class represent a Signature Target that can be part of
the FeatureBinding for a SignaturePolicy (refer SignaturePolicy.FeatureBinding).
Represents a base class for SOAP Message Security Policies.
Any WSSPolicy can be epxressed as being composed of one or both of
two SecurityPolicy components called FeatureBinding and KeyBinding.
This generic structure for a WSSPolicy allows for representing complex,
concrete WSS Policy Instances.
For example, A SignaturePolicy can have a SAMLAssertion as its KeyBinding.
The SAMLAssertionBinding can in turn have a KeyBinding which is a PrivateKeyBinding.
The PrivateKeyBinding would contain a PrivateKey corresponding to the PublicKey
contained in the SAML Assertion of the SAMLAssertionBinding.
