## Functions

### `xmlSecTmplSignatureCreate`

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

*Source:* [include/xmlsec/templates.h](https://github.com/lsh123/xmlsec/blob/1.3.11/include/xmlsec/templates.h#L26)

Creates a new <dsig:Signature/> node with required children.

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.
