SoapMultipleDocumentsSignatureService (Digital Signature Services 5.5 API)

All Superinterfaces:

Serializable

All Known Implementing Classes:

SoapMultipleDocumentsSignatureServiceImpl
```
public interface SoapMultipleDocumentsSignatureService
extends Serializable
```
Interface for the Contract of the Signature Web Service. The signing web service allows to create a new signature or to extend existing one. Different forms of signature: XAdES, ASiC-S or ASiC-E are accepted. The digital signature of a document in a web environment is performed in three steps: 1. Creating a byte stream representing the data to be signed. 2. Hashing of the data previously obtained and its encryption. 3. The creation of the envelope containing all the elements of a digital signature. The process is controlled by a set of parameters.

Method Summary

Modifier and Type	Method	Description
`RemoteDocument`	`extendDocument(ExtendDocumentDTO extendDocument)`	This web service operation extends the signature of a given document to the level of the signature provided.
`ToBeSignedDTO`	`getDataToSign(DataToSignMultipleDocumentsDTO dataToSign)`	This method computes the digest to be signed
`RemoteDocument`	`signDocument(SignMultipleDocumentDTO signDocument)`	This web service operation signs a document according to a previously signed digest, a level of signature, some signature properties and keyInfo.

- Method Detail
  - getDataToSign
```
ToBeSignedDTO getDataToSign(DataToSignMultipleDocumentsDTO dataToSign)
```
    This method computes the digest to be signed
    
    Parameters:
    
    dataToSign - a DTO which contains the documents to sign and parameters
    
    Returns:
    
    the data to be signed
  - signDocument
```
RemoteDocument signDocument(SignMultipleDocumentDTO signDocument)
```
    This web service operation signs a document according to a previously signed digest, a level of signature, some signature properties and keyInfo.
    
    Parameters:
    
    signDocument - a DTO which contains the documents to be signed, the parameters and the signature value
    
    Returns:
    
    the signed document
  - extendDocument
```
RemoteDocument extendDocument(ExtendDocumentDTO extendDocument)
```
    This web service operation extends the signature of a given document to the level of the signature provided. The document is only changed, if the given signature level is 'higher' than the signature level of the document.
    
    Parameters:
    
    extendDocument - a DTO which contains the document to be extented and the parameters
    
    Returns:
    
    the document with an extended signature
