Validation of Xades type signatures in Alfresco ECM

Recently, we developed a signature
validation module for Alfresco ECM compatible with Xades-type
signatures, such as Sinadura Desktop Xades Format (SAR file) and XML
Facturae (Spanish Standard for Electronic Invoice). Previously, we
implemented it for PDF signatures (CMS/PKCS7). We applied it in
an Alfresco Enterprise project in Peru, for Xades DIGIDOC signed documents.

First of all, we included the Sinadura
validation libraries in the Alfresco module, for obtaining the
signature information from the SAR and XML files (which is extensible
with other particular Xades signature types). From Alfresco point of
view, we created a validation aspect where the signature data is
storaged for SAR and XML mimetypes. We developed two menu actions and
their corresponding action-executers for being applied in content
rules. It is also available the option of validating several documents
in one action.

We show some screenshots of the module:

– Menu actions allow to validate
signatures of PDF, SAR and XML files though action menus. It is
possible to select several documents to be validated in one
action.edit properties you can see (but not edit) the signature.

We can also apply a content rule for
validating once the document is uploaded to a space:
