Dim returnValue As ProofDescriptor

returnValue = Me.GetProofToken(request, scope)

protected virtual ProofDescriptor GetProofToken (
	RequestSecurityToken request,
	Scope scope
protected ProofDescriptor GetProofToken (
	RequestSecurityToken request, 
	Scope scope
protected function GetProofToken (
	request : RequestSecurityToken, 
	scope : Scope
) : ProofDescriptor



A RequestSecurityToken that represents the incoming token request (RST).
