What file format would store digital signatures???

Question

This is my situation...

1- I have a web form filled by a user and digitally signed.

2-When submitted by the user, the form goes to the user's supervisor, who will aditionally to the first signature, will also digitally sign the form....

3- After the supervisor signs and submits the form, it should be saved in a file format that:

    a) can be easily read (only) in any enviroment...(Doc or PDF)

    b) Document integrity can be verified with the digital signature properties...

Any suggestion on what would be the best way to do this???   

My idea was to find a way to submit the form to a .doc format as an individual file on a folder in the Sharepoint server.

Thanks in advance!!!!

Answer 1

Hi ,

I understand that you want to submit the web browser form to a format which is read-only and support signatures. I would recommend PDF files. You can convert an InfoPath form to PDF using InfoPath filler: Click File>Save & Send>Create PDF\XPS Document.

If you want to submit the form as PDF file directly without convert ,you need to add custom code in the form.

For more information ,please refer to this site:

You are absolutely correct and that's exactly what I want to achieve.

I do not have the option to go through Infopath filler so it will have to be submitted directly.. I've skimmed over your attachment and I'm in no position take the expense of something like Muhimbi. It may be really good soft.. I do not know, but I can't afford it.

Even though there are some bad comments from the Muhimbi support guy, I will give it a try to the other option with code in your link and see how it goes...

Thanks!! Any other suggestion you may have? I'm surprised that a solution to submit documents maintaining the digital signature is not an standard option in Infopath 2010..

Answer 3

Hi ,

Here is an another option.You don't need to change the form to a PDF file.When you sign a form ,you need to put the signature in a section and choose the data which you want to sign .After you have signed the data ,it becomes read only.So you can use the signature to sign all the controls under my:myFields to keep the form read only.

1. Right click on the section which will hold the signature and choose Section Properties.
2. Choose Digital Signature tab and check'Allow users to digitally sign this section'.
3. Choose /my:myFields in the data part.

OK.. Great.. I've done what you have suggested. The user gets to fill up all the info. When he is done he is asked to signed the form and after that to submit it

When they hit submit...:

1: how would you recommend to send the whole form to a file to disk

2: in a format that maintains the integrity of the form structures, fields, and data

3: the characteristics of the digital signatures (that allows for verification that the content of the form was not tampered), and

4: that can be easily read outside of the environment where it was created (read: pdf or MS word).

Thanks in advance!!!!
