A template has the same structure as the desired result but some of the nodes are empty. XML Security Library gets the key for signature/encryption from keys managers using the information from the template, does necessary computations and puts the results in the template. Signature or encryption context controls the whole process and stores the required temporary data. </p> <div class="FIGURE"> <a name="AEN149"></a><p><b>Figure 1.
