Documentation

Definition

The standard defines 3 types of XML Signatures:

• Enveloped Signatures
• Enveloping Signatures
• Detached Signatures

The default of class CL_SEC_SXML_DSIGNATURE is enveloped.

Use

The usage of the type depends on the scenario. Web-Services use detached signatures.

Dependencies

The processing of the data which is signed depend on own structure definition.

Example

• Enveloped Signatures:

  The signature node is stored as child within the data node:

  <DocumentData>

  <Signature>

  </Signature>

  </DocumentData>

• Enveloping Signatures:

  The signature node contains the signed data as child:

  <Signature>

  <DocumentData>

  </DocumentData>

  </Signature>

• Detached Signatures:

  The signature node and the signed data node have no child relation and may not be stored in the same XML document:

  <Signature>

  </Signature>

  <DocumentData>

  </DocumentData>
