Adobe Reader signature

I have to digitally sign a document and I am using adobe reader. Everything under the sign tab is grayed out so what can I do?

I am having the same issue. I saw the Sign Pane when I first upgraded to Reader XI, but as of late it has disappeared on me. I changed some of my security settings, but I cannot see as to where that may have effected anything with signing. I am not sure what the issue is...did you ever resolve this? If so, please help.
Thanks,
Tracy

How can I find the location of the signature used in the Adobe Reader signature feature?

How can I find the location of the signature used in the Adobe Reader signature feature? I've been using the signature feature for a while now and it works great and I'd like to use it on another computer. However, I forgot where I stored the signature. Adobe finds it with no problems (the signature pops up when I click "Place Signature"), but I have no idea where it is.

Hello,
It's here - C:\Documents and Settings\username\Application Data\Adobe\Acrobat\10.0\Security\

How Can I stop signature fields disappearing on my IPAD Adobe Reader 11

Hi, I am using trial version of Adobe Acrobat XI pro. I have converted a Word document to PDF. I have added text fields, Java scripts to automatically add Todays date as default, Form Reset buttons and Signature fields. File is saved as standard save. All of the above is done in Windows 7 environment. On same computer, In Adobe Reader signature fields are visible although I do not have the means to test it. When the same File is emailed and opened on an IPAD using Adobe Reader 11.2, the signature fields are missing. I intend to have my users access the file (and 30 others like this) on an IPAD. Can someone advise how to resolve the missing signature field issue. It appears that Adobe do not help with such issues as it is not considered an installation issue.

Digital signatures are not supported on mobile versions of Adobe Reader. Other PDF viewers like Readdle's PDF Expert treat them like e-signature fields, allowing the user to draw/apply their drawn signature, but this is not the same as a digital signature. Adobe Reader for iOS allows you to add an e-signature, but it doesn't use digital signature fields for this feature. Instead, you tap the screen, choose the annotations icon, and then the signature icon.

Using iText to generate a digital signature that can be signed in Adobe Reader

I am able to create a digital signature in a pdf using iText. Adobe Reader does not allow that digital signature to be signed. Everything I have been reading suggests that I need to enabe Reader Usage Rights, but that requires using Adobe Pro. I was hoping that I would only need Adobe Reader inorder to digitally sign the pdf, is that possible?

Not without the required rights...

Can you create an electronic signature in a PDF file using Adobe Reader 9

Hello all:
I am filling out an application that I opened using Adobe Reader 9.
It is a PDF document, and at the very bottom there is a field which is meant for my signature..
Is there away to sign this electronically?
Do I need to scan my signature and place it that field?
Can I sign with a pen tool with in Adobe Reader 9?
Or do I need to print, sign the document, scan my document, and then import as a completely different PDF file?
Thanks in advance!!

That depends.
Are they asking you to put a copy of your actual signature on there or are they asking for a "digital signature"?
They are different things.

Adobe Reader Touch (Windows Store app with "modern" UI) does not support any types of signatures yet.
Digital Signatures with certificates
Electronic Signatures (that are legally enforceable)
Signature annotations (hand-writing annotations which may not be secure and legally enforceable)
Adobe Reader XI (traditional desktop app with classic UI) supports #1 and #3.
Adobe EchoSign supports #2.
Adobe Reader for iOS/Android supports #3.

How do I change my security settings in Adobe Reader to allow me to add my electronic signature?

I am trying to fill out a job application that requires me to type my signature, but it will not enter. When I go to File-Properties-Security, it says signing is "Not Allowed". How can I change this to allow signing? Thanks you so much.

Not possible with Adobe Reader.

Adobe Reader XI 11.0.09 Update broke image signatures

I allowed my computer to download and install the latest Adobe Reader XI update, to version 11.0.09. Since doing that, I can no longer sign PDFs. Adobe Reader "forgot" my signature, and prompts me to create a new one, but gives me an error when I try to do so.
The steps I take: I click on Fill & Sign at the upper right. From the Fill & Sign Tools pane, I choose Place Signature. Since Adobe Reader has forgotten my signature, I am prompted by a dialog box that starts with How would you like to create your signature?. I tick the Use an image radio button, then click the Browse... button that appears below it. I choose my signature, which happens to be a BMP file, and click the Open button. Adobe Reader then gives me an error message: This file cannot be used to create a signature. Please select a different file and try again.
I tried converting my BMP file to a TIFF file, but that didn't help.
I need to be able to sign PDF documents again. Is this a bug waiting for a fix, or is there a work-around?
I badly need this feature back again.

Hi, thanks for your prompt responses.
I am a bit perplexed. I take it that, although I have the latest Adobe Reader XI (11.0.10) installed with the latest update 32 and I can open it and use it to read PDF's it is not the correct version for Vista ? As I said when I used the Firefox plug in check, which triggered this whole issue for me, and clicked the red button to update it took me to an Adobe update install page which only offered the 10.1.4 English UK for Windows download (Which you say is actually the correct version for Vista) but this did not complete because it said I have a more functional version already installed which I presume is the 11.0.10 version ?
Do I now need to download the Adobe Reader 'Full Download': Adobe Reader MUI 10.1 - Multiple Languages version 146.67 MB 6/8/2011 or just the Adobe Reader 10.1.4 update, although I may find that I just get the same result as I do using the Firefox update button, it does not complete and I am informed I have a more 'functional version' installed ? Again there are two options for these Updates on the Adobe download page 'All languages' and 'Multi lingual (MUI) installer' and I am not sure what the difference is or , more important, which to use and the Help>About Adobe Reader offers no clue.
Further advice appreciated as I am a bit flummoxed ! Thanks .

In Adobe Reader 10.1.4 my signatures are valid, in version 11.0.10 they are not?

I have a PDF document with two signatures.
If I open it in Adobe Reader 10.1.4 the signatures are ok.
If I open the same document in Adobe Reader 11.0.10 the first signature is marked invalid: "Document has been altered or corrupted since it was signed".
Does anybody understand why this is?
I have the feeling this is a bug in Adobe Reader 11.
Thanks,
Corné
You can find the PDF here: WeTransfer

Can you please try repairing the application from the Control Panel.
Also, could you please let me know if this issue was happening with Reader 10.1.3 as well.

I recently udpated to Adobe Reader 11.0.7 and now I can not open signature protected documents. ?Porque? What is the fix?

Pasting all the conversation so that others can get help from the discussion.
Hi David,
Can you please try disabling protected mode and see if you are able to open these files.
To disable protected mode:
Select Edit menu -> Preferences -> Ubcheck Enable Protected Mode at startup and restart Adobe Reader.
Note:
"Purpose of Reader XI Protected Mode is to keep your system safe from PDF based exploits and keeping protected mode OFF will leave your system vulnerable.”
Please turn back on the protected mode checkup after this testing.
This seems to be a fix! Thank you for your help. Now comes the tricky part. I have to deploy this as a package across a gov. network using SCCM. How do I get this to all the users with "enable protected mode..." unchecked. I can't give them something that does not work out of the box.
Hi David,
It is not advisable to turn off protected mode as Purpose of Reader XI Protected Mode is to keep your system safe from PDF based exploits and keeping protected mode OFF will leave your system vulnerable.
Please let me know few details so that I can reproduce the issue at my end.
1) Will it be possible for you to send any test file in which the issue is reproducible.
2) Can you please check where the certificate (from which the PDF is signed) is stored. (Is it stored at Trusted Root Certificate Authorities or some other store?)
3) Do you use any other tool other than Adobe Reader plugin to digitally sign/ open a PDF ? (Is any tool other than Adobe Reader is involved?)
Thanks,
Shakti K
Hi David,
Please do the below test to see if the issue occurs due to signatures applied to the PDF document.
1) Launch Reader go to Edit -> Preferences -> Security (Enhanced) and check "Enable Protected Mode at startup" and clock OK.
2) Goto Edit -> Preferences -> Signatures and select Verification . Uncheck "verify signatures when the document is opened." and click OK.
3) Restart Adobe Reader
4) Now open the digitally signed protected PDF file in which the issue was observed.
Please let mw know the observation.
Thanks,
Shakti K
It has nothing to do with the signatures applied. Any document with a
signature block, even blank documents, will not open unless the "enable
protected documents at start up" is unchecked. It is the same across the
board for all documents weather signed or unsigned with a signature block. I
have it working on my machine, I just need to figure out how to install over
the network with the block unchecked during installation.
1. Attached form
2. I am not sure where reader pulls the cert from. They are all in a trusted
root CA because all certs are miiitary
3. Other tools used
ActivClient CAC x64 (6.2)
e-Sign Desktop 6.6
Thanks again for the support
Thanks a lot for all the information.
A doubt : If the document is not signed (like you mentioned unsigned documents also face the same issue) then how exactly the document is protected. Is it protected using any certificate?
I cannot find any attached PDF form . Please resend it again.
I am unable to reproduce the error now. Even with the protected block check.
Im not sure if there was a Group Policy change that enabled this. As of now,
it looks like the issue has been resolved. I appreciate all the help.

Signature verification changes in Adobe Reader 9

[ I posted this message in the "Adobe Reader" forum, but I have realized that the post that I reference in my message belongs to this "Acrobat SDK" forum. So I've decided to send my post here, although this is not an Acrobat SDK question. Excuse me if you thing that my question should not be in this forum. ]
Hi all,
I have found this post in this forum talking about changes in Adobe Reader 9 related to signature verification:
http://forums.adobe.com/message/2439480#2439480
I have another scenario:
A PDF with two signatures.
After the first signature, a new page was added and then the PDF was signed again (using signature appearance).
Using Adobe Reader 8.1.5, the result of signature verification is successful for both signatures.
In fact, the byte range of the first signature is intact after adding the second signature.
But if I open it with Adobe Reader 9.2.0, the verification result is invalid signature (for the first signature): the document has been modified and there is a new page.
Since it seems that Adobe Reader 9 has added some new checks when verifying signatures, does anybody know (or know where can it be found) the list of new signature verification requirements of Adobe Reader 9 ?
Or the list of changes allowed in Adobe Reader 9 that do not invalidate signatures ?
Maybe a list similar to the changes allowed in the three types of certified signatures (TransformParams)?
Thanks a lot in advance

Thanks, lrosenth.
The document I was searching for is in Adobe site and is called "Adobe Acrobat 9 Digital Signatures, Changes and Improvements".

Problem creating PKCS# 12 Digital Signature in Adobe Reader X - where do I confirm the Password?

I cannot create a PKCS# 12 Digital Signature in Adobe Reader X. It says the passwords don't match when I create it. The problem is, I never was asked to confirm the P/W when I created it. It asked once for the P/W and then the only thing I can do is click "Finish" and then it says my P/W don't match. I am able to create a DS on my other computer using Reader 9 (and it did ask me to confirm the P/W when creating). I have re-booted my computer and still it will not work.

You'll need to ask in the Acrobat Pro forum. There are people there with expertise who can answer this. I use Acrobat myself, but I'm a novice when it comes to signature settings.

Digital Signatures in Adobe Reader 8

Hello,
I am trying to use adobe reader 8 to make a digital signature on a pdf document but I run into an error code when I try to sign and save the document. It comes up saying: platform encyption
keyset does not exist
error code: 2148073494
This was after running through this document on the adobe website: http://http://help.adobe.com/en_US/Reader/8.0/help.html?content=WS58a04a822e3e50102bd61510 9794195ff-7d4b.html minus the first HTTP that is in this line. Has anyone tried this or seen this error?
Thanks in advance, have fun
Dave

What I found is that the document first has to have usage rights enabled in Acrobat Pro 8 or 9, then you can use Reader 8 or 9 to sign the document.

Signature option in Adobe Reader.

Why is the signature option in Adobe Reader one "greyed out" for iPad users, you can no longer access your signatures and add them to a document ?

Hi F & F,
If you are really looking to create a cryptographically secure digital signature then you need to create a custom signature appearance. If on the other hand all you want to do is add a picture of your signature you need to create a custom stamp. In order to create a digital signature you need to have access to a digital ID (a public/private key pair), and before going through all of the steps of creating a custom signature appearance is this what you intend to do? If so then check out 4 Custom Signature Appearances — Digital Signatures Guide for IT for help in creating the signature appearance. If you just want to create a stamp then look at the tips at Adobe Acrobat X Pro * Create a custom stamp.
