### xmlSecTmplSignatureCreate ()

    xmlNodePtr
    xmlSecTmplSignatureCreate (xmlDocPtr doc,
                               xmlSecTransformId c14nMethodId,
                               xmlSecTransformId signMethodId,
                               const xmlChar *id);

Creates new <dsig:Signature/> node with the mandatory <dsig:SignedInfo/>, <dsig:CanonicalizationMethod/>, <dsig:SignatureMethod/> and <dsig:SignatureValue/> children and sub-children. The application is responsible for inserting the returned node in the XML document.

#### Parameters

doc | the pointer to signature document or NULL; in the second case, application must later call `xmlSetTreeDoc` to ensure that all the children nodes have correct pointer to XML document. |
c14nMethodId | the signature canonicalization method. |
signMethodId | the signature method. |
id | the node id (may be NULL). |

#### Returns

the pointer to newly created <dsig:Signature/> node or NULL if an error occurs.

### xmlSecTmplSignatureCreateNsPref ()

#### Parameters

doc | the pointer to signature document or NULL; in the second case, application must later call `xmlSetTreeDoc` to ensure that all the children nodes have correct pointer to XML document. |
c14nMethodId | the signature canonicalization method. |
signMethodId | the signature method. |
