Sinadura connector for Nuxeo DM

Sinadura is an open source java-based multiplatform desktop application for signing PDF's, that provides a simple solution for digital signature and electronic invoice processes. This software guarantees the integrity, the identity, and the no repudiation of any PDF document, for example, in payslips, contracts, invoices or certifications.

The legal disquisitions regarding to the storage, custody or preservation of many of these signed documents for companys and public administrations recommend the use of enterprise content management systems such as Alfresco ECM or Nuxeo DM. The ECM systems can help us to manage the full document lifecycle, involving sinadura desktop client in digital signing processes/workflows with this integration. The process of signing is performed on the client side, and therefore, we can use both smartcard (pkcs11) or software certificates (pkcs12) for the common signing features of sinadura (visible stamps, customized background images, TSA timestamps or OCSP validation)

In previous posts (in spanish), we commented the integration of sinadura client with Alfresco ECM repository, which covered the basic ECM functionality for adding, updating, browsing, downloading and deleting documents from sinadura client. The ECM functionality is now implemented in sinadura client for Nuxeo DM 5.3.x via REST API, including the next repository actions:

• Add to Nuxeo path: This option allows us to add selected PDF documents in sinadura client to a chosen workspace in the Nuxeo repository. The final path  is selected with the help of a sinadura browsing component.
• Add to Nuxeo default path: The default path is defined with the browsing component in sinadura preferences. Then, the selected pdf's are added directly to this default path.
• Download from Nuxeo: This option allows us to browse the Nuxeo repository and to download locally a chosen PDF file to sinadura client.
• Update in Nuxeo: With this option, we can update a file in the repository, which can be previously downloaded from Nuxeo repository (and signed with sinadura).
• Create Workspaces: We can create new workspaces from sinadura client in the repository.
• Delete from Nuxeo: We can also delete a document in the repository via this option (always with the necessary permissions).

I let here some of the screenshots of the sinadura connector for Nuxeo. For example, the Nuxeo repository authentication preferences:

The default path for adding PDF's in Nuxeo repository is also selected in preferences window:

We are currently working in sinadura 3.0, which will allow to sign any type of file (not only a PDF file). Please contact us, for more information about the connector, or about digital signing and enterprise content management services.
