PDF Signing Info

Functionality what we required:
We have a PDF on ASP.NET web page with some content related to business contract. User has to accept the contract by signing (clicking the buttons) on that PDF. It may be possible user have to put more than one signature on that PDF. The numbers of signatures required on PDF are coming from the database. After signing on PDF (putting the signatures at all required places) we have to update the status in database that PDF has been signed. We need not require saving the PDF
Implementation approach, which we are following:
1. We have put two hidden label controls and the buttons for signature at required places through JavaScript in PDF. One label control has a value for total number of signatures required in PDF and another label for maintaining the counter of the number of buttons clicked for signing the PDF document. On clicking the button it becomes disabled and increase counter in second label control. We match the value of label controls, if value are same, all the signatures has been placed otherwise we display a JavaScript error message that informs that all signature need to put for complete signed PDF document.
2. We have created a web page having an Iframe and a submit button. In Iframe we are displaying the PDF document.
Till here every thing is working fine.
Required:
The submit button has to send the notification to web server that the PDF document has been signed.
Problem, that arises:
How we will check that all the signatures have been put or not inside PDF on clicking the submit button on the web page?
Does anyone have better opinions for the implementation of this functionality, please suggest.

>How we will check that all the signatures have been put or not inside PDF on clicking the submit button on the web page?
You'd need a PDF library that can do this detailed, and rather
complicated, analysis. I think the Adobe PDF Library would do this,
but it would be awkward. You can't use Acrobat on a server, so its API
can't help.

Joint pdf signed for printing

i want to joint pdf signed for printing or to have a mutiple printing, is-ti possible?
Thanks

The question is, have I set up the PDF correctly?
If you want all color converted to AdobeRGB.
Composite printer's often expect RGB, but they usually provide RGB output profiles like this Epson output profile for glossy paper.

Adobe pdf signing with Topaz

Hi All,
we are facing an issue while signing a pdf. i have a pdf attachment in my gmail and when i download it, i'm asked whether to Open/Save it. I choose Open and the pdf opens up. When i try to sign it, i get an error which says:
"The Document Could not be signed
there was an error when attempting to commit this signature.The document was not saved.
The file may be read-only, or another user may have it open. Please save the document with a different name or in a different folder."
Now, i have searched the internet and found a setting about protected mode at startup...this setting is not available in Adobe Pro 8.2 Please help. Thanks.
Version Info: Adobe Pro 8.2
Topaz 1.5
Browser IE8
OS: Win XP with SP3

Does the document you're trying to sign have any security restrictions?
You might want to contact the Topaz folks since applying a digital signature with their pad relies on a plug-in they supply. You can get the latest one here: http://www.topazsystems.com/software/download/plugins.htm

Mobile PDF signing

So I have been trying to create a "service report" for our company. I created a form with forms central, and all in all I just love the way it works. I tried doing it via excel and importing into reader to create a form. Maybe I was doing something wrong, but it would never read all my text boxes I had in excel. Then I would have to create text fields, which would be dozens! Forms has been really worth it now!
Anyways I am trying to iron out small details now. The PDF is built, and functions awesome except for a few "minor?" things.
1)This form is going to be distributed amoung a bunch of my workers, so they can fill out electronically on a tablet or phone. I do want to have signatures in there, which I can make happen. The few problems I am having is although the signature is created on the tablet or phone it never wants to show up when the office computer accesses the new saved file. I also want it to be able to be recognized on office computer in the actual signature space. Not just a "picture" that is displayed on the screen. Just for lockout pourposes mainly. We will have customer signatures on site, I want to be able to lock out all fields once it has been signed. So I am not sure if once I can get the desktops to recognize a mobile signature, if it will all just fall into place or not.
2)I have been looking into this whole echosign thing, but no matter how hard I try I can't find it anywhere on the mobile adobe reader app. Not sure if I am doing something wrong, but I am on the latest version. Just trying to see if it would be a better way for distribution. Basically now, the easiest way I can find of doing it is this: We have the "orignal" file on a google drive, that would then have to be saved to each device in order to edit of course. From there you would have to duplicate the file and rename it to your job and date. Then it could be uploded back into drive where the office can access it at anytime.
3)*edit* I also seem to have an issue when I try and put my signature options in. When I go to select the fields for read-only portion it won't select any checkboxes or anything. When I select select all it will select them, but as soon as I hit ok it all goes away and nothing happens!
Any input is MUCH appreciated. I tried doing a search but could really not find my answer.
thanks in advance!

Override default pdf signing method

I am trying to create an extended digital signature application to sign a PDF file (i want to override the default signing method used by the PDF), i went through a research and found that co-sign already done it before, please check the following link:
http://www.youtube.com/watch?v=WgsQgJWeGZE
i need to know how to create my own digital signing tool and integrate into Adobe reader??,
thank you for your help

I need "two up (cover)" not (facing), because it jumbles the pagination. c1 and c4 should be seen as single pages, and the rest of the doc should be spreads.
Hi Bill.
Yes you would want the "Two up (cover)" when you have layout as attached pdf, but that was not what was in the question, so thats why I suggested tge other version
("So that when a user opens the pdf in Reader it is initally shown as 2up (two page spread)")
Full screen mode is primarily intended for presentations - as a Powerpoint slide alias, so it would make no sence to show a spread, cause you would want to show a slide.
If you want the full screen to show as you described, make page 2 and forth as a one page (spread size).

PDF signing signature file size increase in increment 3mb

Hello,
Have anyone seen Adobe Reader digital signature insert and file increase from 85kb over over 3mb? The current Adobe Reader use is 9.x and every time inserting PDF signature it changing the size largely. The signature file less than 95kb. Please let me know if you seen this and a fix for it.
Thanks
JT

Hi Ankit,
Thanks for following up and the issue has been resolved since I found tips from the forum below. The OS is WinXP Pro and current version Adobe Reader 9.4.6. It work after de-select the option under preference so I’m good to go. Maybe you can posted this on your site as “fixed” for those experience same issue as I’m.
Re: ACROBAT DIGITAL SIGNATURE ADDS 700KB TO .PDF FILE SIZE"
go to edit>preferences>security.
click on advanced preferences then select the 'creation' tab.
De-select 'Include signature's revocation status when signing'
the extra data is the CRL list that gets embedded with the signature if the above preference has been selected.
Thanks

PDF Signing Solution

Clients want simple solutions; moreover many are not IT lovers and just want things to work. We send out a lot of PDF’s that need signing. EchoSign far too complicated. Most clients will be running Acrobat reader on a PC or hand held device. What is the best and easiest method to embed an ability for a recipient of a PDF using Reader to sign? If you start using JavaScript popups etc then they often do not function on mobile devices. Is there are way of embedding something that will allow the recipient to see that they have been asked to sign and when they click to sign it confirms they have accepted the document which they can then email back?

Hi,
The short answer is no.
The signature status only applies to the electronic version of the file. Once the file is printed we have no way to test if the contents on the printed page are the same contents that were signed, thus we suppress adding the signature status to the printed output.

Best practice to verifing digitally signed PDF (signed using localley generated ceritificates)

Hi,
I have signed a PDF using a locally created Microsoft Digital Certificate inside my organization.
As part of the approval workflow, I emailed the signed PDF document to another person in my organization (within the same network) for review and final acceptance.
The issue I'm facing is that when the other person opens the PDF, my signature status will show as not verified. Even though, I have created it while I'm connected on the network.
What are the steps that the other person need to follow so (s)he can verify locally generate digitally signed PDF either manually or in an automated manner?
Is there a server-side tools provided by Microsoft to do the verification automatically? Or, I have to do it manually? Any 3rd party plugins you recommend to ease this verification process?
Appreciate your help,
Yasser

There are several preference setting related to this, depending on what version you're using. For example,
Acrobat 9: Edit > Preferences > Security > Digital Signatures > Verify signatures when the document is opened
Acrobat 11: Edit > Preferences > Signatures > Verify signatures when the document is opened
To fully validate, they will need to add your certificate to their list of trusted certificates or you can set up the Windows Integration feature under Preferences.

HELP: signer info doesn't match info of other classes in the same package

I have several jars which need to be signed. They contain several applications and packages which
are split up based on which parts are needed by server vs client code. How do I get rid of this error?
I'm signing all the jars using the keytool and jar signer in java 1.3.1. I generate a certificate file.
My assumption is that each time I sign a different jar, the info is updated in the keystore and
certificate file. What might I be doing wrong when signing multiple jars?
(Yes, code from the same package may be in different jars. I don't have any controll of this,
I'm not in charge of the build and distribution of the various packages).

App for hotel pdf sign in forms -

I want to take our hotel check-in form and set it up for digital sign-in as guests arrive. The form would be then stored and a new one ready-to-sign. How do I do this?

You can't do it with Reader. You need to purchase Acrobat for that.

I am setting up for the first time, i didn't get the print out while setting up with my sign info

Multiple users signing the pdf form

I have date fields in the pdf form in which the signed date is inserted when each user signs the form. Although the Digital Signature property in pdf provides date property on the signature image. But we have a business requirement to show date field separately on pdf form. Suppose User1 signs the application and the date is inserted in its corresponding date field. But when User2 signs the application and the date is inserted the signatures of User1 gets invalidated.
Is there any way by which pdf field can be made editable even after one user signs the application?

PDF supports multiple signatures on a single form or document. When using a form, you can use field collections to associate specific fields to a certain signature and lock those fields after signing, while leaving other fields accessible. There are many posts throughout this forum that discusss this functionality, here is one... http://forums.adobe.com/thread/769340
As for signature status, applying a second signature (or more) after a form or document has been signed will NOT invalidate the original signature, however it will change the status of the original signature to something like "Valid with signed changes". Each subsequent signature will change the status of the previous signature, but this is not the same as invalidating a signature.
This behaviour is by design as a signature applied to a PDF signs the entire byte range of the PDF, not just a portion of it.

How to fill up pdf forms & sign pdf contracts using digitizer pen & tablet?

Greetings,
I travel a lot and bring tons of documents for clients to sign. As I am trying to cut down on travel weight, i fancied upon the idea of using a digitizer such as the Genius EasyPen i405 to fill up pdf forms and sign contracts so i wouldnt have to scan, save and email the forms back to the office thousands of miles away. I would like to know if it is possble to do that using such a device. If its possible, how? I use acrobat X. Any advise you can give would be greatly appreciated. Hope to hear from you soonest. Thank you.

Thanks for your response jallisy. I just thought about this because i read somewhere that the pen acts like a mouse cursor when you move it around the digitizer. I figured the pen could act as a mouse while the digitizer could act as a mouse pad, as such the size doesnt really matter, considering you need to press a button on the pen to engage the digital ink and you use the computer screen as your guide. I havent really tried one but am just starting to explore the idea as tablets like the Ipad are now allowing users to fill up forms and sign pdfs with a finger or a capacitive pen. Youtube offers all these interesting pdf signing and editing with the Ipad. I just really dont want an Ipad. I still think a solution is just around the corner. But i am not willing to buy an expensive tablet with limited storage and productivity features over a real laptop.
The genius site for the pen stated that i can sign microsof office docs but no pdf was mentioned. I guess they have a special software for that but the people at genius havent gotten back to me yet. Another way i was thinking about was converting all the pdfs to word, sign the word document and then save as a pdf again ... the document is prone to be edited though and formats could be accidentally changed so was really thinking about doing this directly with a PDF instead.

Where is the sign-in box for Adobe PDF Pack?

My plan is an Adobe pdf pack. I used to be able to open a pdf, sign into my account and then convert, sign, etc. Now I cannot see the sign in option at all. I just got a new hard drive and installed Microsoft office 2010. Any suggestions?

Sign-in where: in Adobe Reader, or on the PDF Pack website?
On Adobe Reader there is no sign-in option; you just provide your Adobe ID & password in the Preferences (Adobe Online Services) panel.
