Digital Signature in Alfresco

dgenard

I would like to announce the availabilty of an Alfresco extension to support digital signatures.

With this module, end-users are able to digitally sign a document very easily, direclty from the Alfresco web UI.
Digital signatures can be used in the context of an Alfresco workflow, or as a simple action.

The implementation is based on standard certificate technologies for optimal security, and gives legal value to your documents.

See a presentation and a demo movie of the module on our website (in English)
http://www.cediti.be/en/solutions/content-management/the-digital-signature

or (in French)

Feel free to contact us for more details,

Cool, that's a very useful extension for enterprise application of Alfresco.
Nothing opensource tough ? 🙂

I think what you are saying is that this would make a very nice forge project! No?

Does somebody have more technical informations about this module ?

Which browsers are supported ?
Beyond the fact that it puts the signature in the document, is there some linked aspect to store informations on signature on the binder ?
Does it allows multiple signatures ?

Which is the cost of this module ? Do we get source code buying it ?

Hello,
here are a few answers.

Which browsers are supported ?

All common browsers are supported.

But an important question is which type of Private Key Infrastructure (PKI) you will use.
Mutlitple types of hardware configuration may be used for digital signatures : smartcards, usb-tokens, certificate stores, …
The module currently supports smartcards, but other configurations might be supported in the (near) future.

Beyond the fact that it puts the signature in the document, is there some linked aspect to store informations on signature on the binder ?

Not yet.

Does it allows multiple signatures ?

Strictly speaking, it currently allows to put multiple signatures on a single PDF document. But the way multiple signatures will be used in the context of an Alfresco workflow will be improved in next releases.

Which is the cost of this module ? Do we get source code buying it ?

Price depends of a few factors : deployment infrastructure, custom adaptations, support options, … You'll get the complete source code with the module.
The module is production-ready for some environments, but its development is still ongoing to support other deployment configurations.
We progress on a demand-driven way, and we develop first the most requested features.
So, for technical and pricing informations, send an email to info@cediti.be, describing the context in which you plan to use it. We'll then be able to send you a more precise proposal.

Best regards,

Hello.

I am currently working on Alfresco project in my company. We plan to use Alfresco for storing scanned images in jpg or tiff format. We also have a need to digitally sign these image documents. Is it possible to digitally sign these kind of non pdf documents with your module?

dgenard

No, not yet.
Only signatures on PDFs are currently supported.

My company uses Entrust for its PKI, with all of our users having an entrust client installed. We also package Adobe Reader/Acrobat internally to include an Entrust plugin for applying electronic signatures to signature fields in PDF documents. We do not use a card reader, but merely a password authentication challenge to sign documents through the entrust PKI CA.

A question about this Alfresco module: how are the signature fields added to the PDF created in a workflow. From your demo, they appear to merely be appended to the bottom of the document. Is there a way to design a document template in the source media (say MS Word) with a pre-defined signature place-holder. Then when a workflow generates a PDF instance from the source template, convert the place-holder to an Adobe signaure field. When the sign document action is performed in Alfresco, have it launch the PKI client to generate the signature event for the target signature field in the PDF.

This mode of use would be very interesting and would be ultimately adoptable for all of our document management use cases.

Hello,
indeed, we plan to improve the support for customizable positions of signatures (page and coordinates).
Thanks for your interesting suggestion. We'll study its feasability for future releases of the module.

Denis

I'm glad to see that positional functionality is already in the works, the would be a good gap filler as the proposed automated place-holder functionality is developed. I would like to contact you concerning further evaluation of your e-sig module.

hi,

if u know how to extend alfresco UI to write your own menu , signing a PDF file programatically is pretty simple.
moreover you can place the signature anywhere in the document.

It's bad …. maybe new version on Alfresco support digidal signature ?

Please help me

As Sourcesense (http://www.sourcesense.com) we're starting up an Open source project for supporting a generic open source stack of Digital signature on top of Alfresco.
Description is still in Italian, but working to target it to all EU countries (especially Italy and Netherlands)..
You can find more info and stay posted here:

Any contribution is of course welcome!

Hi all!

I would like to ask you what are the progress about your Digital Signature module for Alfresco.

I'm interested in developing this function as extension of the Alfresco ECM so I would like to exchange discussions and opportunities about it.

Ivano

_sax

We're, too interested in such an extension. Is there still any progress on that project? What are the current functionalities? Is it bound to file formats or to a specific hardware or Alfresco version?

jonvargas

Are there news about this?

We are also interested in a electronic signature solution for current Alfresco versions. If someone has found an up-to-date solution, please tell us.
Thanks in advance.

The link here is not containing any source about the digital signature ,if you have link here the exact one which is working for digital signatures provide that is very helpful.
