Properties of the Signature Field

How can I extract certain properties of the Signature Field?
Basically I want to extract the name of the Signator in order to assign rights. I also have a "Approved Name" Field that the user fills out and I feel I can eliminate that field and ensure accuracy.
Any Advice?

Take a look at the SignatureInfo object in the Acrobat JavaScript reference. You can get a SignatureInfo object in a Designer form using script like the following.
var acroSOM = SigField.somExpression.substr(15, SigField.somExpression.length - 1);
var acroField = event.target.getField(acroSOM);
var sigInfo = acroField.signatureinfo();

Populating the Signature field of OIM UPA table

The OIM UPA table has a SIGNATURE field which customers can use for storing digital signature of the snapshot (for non-repudiation purposes).
By default - the value of this field is "NULL" in the database.
Did not find any documentation on how this field is populated.
Has any one made use of this non-repudiation feature.
Thanks,
Chetan

If you want this functionality it is actually not that hard to create a scheduled task that populates the signature field using a third party non repudiation provider.
Doing local non repudiation is per definition non useful so you do need a trusted third party (i.e. Guardtime (http://www.guardtime.com/)) that provides the service.

How to left align the signature field of dynamic pdf

Hi,
I am working on dynamic (interactive) pdf and using Adobe LiveCycle Designer (Adobe Acrobat 9 Pro). My problem is that I cannot align left the signature field of my pdf. I can align left, right and center for textboxs and cannot just do that for signature field. When I couldn't do that from GUI I went to XML code for signature and tried this:
<para hAlign="left"/> but it still didn't work. Ideally it should have worked.
I would really appreciate if you could help me.
Regards,
Kiran

Use skinning. Use the following skin selector:
af|panelFormLayout::label-cell {text-align: left; }If you want to apply it only on particular panelFormLayout, then set a custom styleClass on the given <af:panelFormLayout> tag (for example, <af:panelFormLayout styleClass="MyStyleClass" ... >) and use a styleClass-dependent skin selector:
af|panelFormLayout.MyStyleClass::label-cell {text-align: left; }Adding a custom skin is easy. If you do not know how, see this topic in the documentation: 20.2 Applying Custom Skins to Applications

Setting up the signature field to work with Entrust

Good afternoon everyone,
Im looking into signautres today and i would like to get a complete walkthrough as to what i need to setup under the signature fields when i press the "settings" button.
Right now there's a bunch of tabs that are available but i hhave no idea what information is required under each one in order to have the Entrust key work with them
My goal is, right now, is to just setup the signature field so that it uses Entrust certificate info of the user trying to sign my form. I have no idea how to get this started
I found my Entrust digiture signature file, i think its got the following extension: .p7c but that dont seem to be enuff to get me going.
When i press into the signature field, i want to populate this one automatically based on the user's entrust cerficate info, Help!!!!!
If you need more details, i will gladly add it to the post. I just really want this to work
Thank you so very much,
Patric

each of your employees will require their own pfx/p12c/entrust key. if you use unverified certs (ie. you created them yourself or they are not from a trusted CA) then when another user opens up that file on another machine, they may find the sig is unverified since they cant' verify the sig.
when they click on the sig field, it'll bring up a dialog box to select the key and require them to enter the pwd.
After that, i think reader remembers and it'll show the last sig file used in the drop down by default. The user will only need to enter in their pwd.
When they save the file their sig will be embedded into the form.
You may need LC ReaderExtension to extend your form so ppl can save and can add digital sigs with Adobe Reader. Otherwise, they would all require Acrobat.

Problem with the Signature field

Hi All,
Good day. I am having problem making a script work in the Adobe LiveCycle. Basically what I am trying to achieve is lock most of the fields on a form when the signature field is click. Note: Not all the fields should be locked. I then wrote a sample script with one of the field as follows:
if(employeeSig.rawValue !=null){
EmployeeLastNa.access = "protected";
But surprisingly it does not work. I have placed this code on the Click, PostSign, and even PreSign events, respectively, but it does not work. I am just wondering what I may be doing that is wrong.
Thanks

Hi -
rawValue does not work on signature fields, so that code will do nothing. Use the collection feature in the signature panel to lock particular fields:
Create a collection then modify it to lock whatever fields you need.

Adding an image when signing, but not in the signature field, in Reader

Hi,
I would like to know if it is possible to add an image to a pdf document when I sign the document in Reader.
I do not want to add the image in the signature field as a signature, but rather below the signature field. The image is 'n barcode providing me with more information on the signature.
I have looked at the Stamper example, but this functionality is not avialable in Reader.
Thank you,
Magda

If you insert after signing you will break the signature!! You need to do any such stamping BEFORE signing.

I haven't used MailForExchange so what I am about to say might not be applicable BUT if you press the * key on your keypad, this should bring up the Extra Characters page - on here you should see the CR key which looks like an arrow going vertically down and then horizontally off to the left - select it.
Does this work ?

I would make the signature field read only until something is entered in the mandatory fields.

Mina,
You can use LiveCycle Designer's Action Builder to easily achieve this.
Please go through online documentation for the specific version of LiveCycle Designer that you are using.
It is intuitive and very easy to use Action Builder (You will find this option under Tools Menu item of Designer).

How do I lock a pdf except the signature field?

I'm using Acrobat X Pro. I want to send a form for others to sign, but I don't what the signer do anything to alter the contents of the form except signing. Can I do that? If I can, how? Thanks!

You can certify your PDF (provided that it does not have any signatures yet). However, the permissions granulation in Acrobat UI does not allow you to distinguish between signature fields and other field types. So, if you allow others to sign this PDF you also allow them to fill other form fields, which is not what you want. You need LifeCycle solution that has more granular permissions handling but this is an expensive piece of software. If you distribute many PDFs like this it may make sense for you. If your volume does not justify this investment you can do the following:
If you do not have other signatures you can flatten your PDF form (Google "flatten PDF form in acrobat x" to learn how to do it), add one or several new unsigned signature fields, certify with "form fill-in and signing" permission (this PDF does not have any form fields other than signature fields anymore), so that the content cannot be changed and send it to the signers.

Digitally Sign All Signature Fields in the Active Document

I have a script which will sign a single digital signature field by the field name.
I need to revise the script so it will sign multiple/all signature fields in the active document without having to put the field name in the script, as the field names will vary with each document.
Can anyone please advise how to modify the script to sign all fields in the active document regardless of the field name?
function myOtherTrustedFunction()
app.beginPriv();
// Get and login to security handler
var oSigHdlr = security.getHandler( "Adobe.PPKLite" );
oSigHdlr.login( "123","/c/Documents and Settings/name/Application Data/Adobe/Acrobat/10.0/Security/FirstNameLastName.pfx");
// Setup Signing Properties
var chk = this.getField("Checked");
if (chk != null) {
// Apply Signature and save back to original file
var bRtn = chk.signatureSign({oSig:oSigHdlr, bUI:false, oInfo:{password:"123"}});
app.endPriv();
Any assistance will be most appreciated.

Thank you for your help, the script will now count only the signature fields which have not been signed.
I have added the second part of the script to then sign all of the blank signature fields.
The script is only signing one of the digital signature fields instead of all of the blank signature fields.
Can you please advise how I can modify the script to sign all of the blank signature fields?
var count = 0;
for (var i = 0; i < numFields; i++) {
    // Get the current field object
    f = getField(getNthFieldName(i));
    // If it's a signature field and not already signed, increment counter
    if (f.type === "signature" && !f.value) {
        count++;
var myEngine = security.getHandler( "Adobe.PPKLite" );
myEngine.login( "123", c/Documents and Settings/name/Application Data/Adobe/Acrobat/10.0/Security/FirstNameLastName.pfx" );
// Sign the field
f.signatureSign( myEngine,{password: "123"});

How do I delete a digital signature field?

I have Adobe Acrobat Pro 9 on Snow Leopard. I created a digital signature for a PDF file but it didn't look good, so I decided to delete it. I figured out how to delete the signature, but the signature field with the little red arrow did not delete with my signature. I want my PDF form to revert to the way it was before I created the signature. I cannot simply close the PDF without saving because I'd lose all the information I've already entered. Stupid me forgot to save before attempting the digital signature.
HOW CAN I DELETE the digital signature field? Help!

Hi SM,
The place to look for permission settings is on the Security tab of the Document Properties dialog. You can get there by selecting the File > Properties menu item and then select the Security tab.
One thing to note is if the file is Reader Enabled you will need to use the File > Save a Copy menu item to create a non-Reader enabled version of the file. You cannot edit a Reader Enabled file. As an aside, the Save a Copy menu item won't be there if the file is not Reader Enabled.
If the file was created using Designer (which is only on Windows and I know you are using a Mac) then it has to be edited in Designer.
If the file was certified, then you need to remove (clear) the certifying signature before you can edit the file, and to do that you must have access to the private key that was used as part of that signature operation.
Finally, if the file is encrypted (e.g. Password Security or Certificate Security), you can edit the file, but you have to get Acrobat to realize you are the document owner which means you need the Permissions password or or logged in using a document owners digital ID (the former is only for Password Security and the latter is only for Certificate Security).

How to make signature field work for reader users? Security settings change when doc is extended???

I've been struggling to correct a problem all week and am at my wits end. Customer service was no help as the person I spoke with could barely speak english let alone understand the problem as I explained it to him. Hoping someone here can provide some insight, here's the issue:
I'm using a Windows 7 Professional OS. I created a Microsoft Word doc and used Adobe Acrobat XI Standard to create a form from it. It automatically detected the fields, which includes a signature field. I went through fixed it all up how it needed to be and did "save as other - reader extended pdf - enable forms fill in & save in reader".
The document is a report that will be sent to a small number of people that have to fill it out, digitally sign and return and I'm assuming that most if not all of them will open the document using the free Adobe Reader. So I thought extending it is what I needed to do to make sure they could fill it out, save it to their computer if need be, and also sign digitally. The signature field was automatically added in by acrobat for me and I did not change the properties of it at all except to add a border.
When I open the form in Reader (also XI) I can fill out all the fields, save it... but not sign it. The security settings say signing is not allowed even though I went back to the original pdf form and the security settings on it say allowed for everything. I don't know how to fix this... please help!!!
I've attached some screen shots but can include more if needed...

I don't have the Enable More Tools option under Reader Extended PDF. I just tried to download the XI Pro trial version and it won't complete installation because of the standard version I already have. Any advice or workarounds you know of? Going to the boss for $$ to upgrade to Pro is what I'll consider my last resort if the issue is truly that I have to use Pro to enable more tools for reader.... I appreciate your reply though. I sat here all day yesterday fingers crossed that SOMEONE would give it a go!

Do you have to distribute a form in order for a signature field to work?

I looked through all the settings on Adobe Acrobat 9 Pro and I haven't been able to figure out how to save a pdf so that when I open it in Acrobat Reader, I can sign the signature field. When it's in Pro, the field works just fine and the document properties say that signing is allowed. However, if it's opened in Reader, it will not allow the signature box to be signed, as the options are all greyed out. When I look into the document properties while the pdf is open in Reader, it says that signing is "not allowed".
So far the only way I've been able to get the signature field to work is by distrubuting the form and opening up the distrubuted form (which makes sense). What I'm wondering is if there is a way to allow for signing a pdf if it hasn't been distrubuted.
Any help anyone can give wil be appreciated.

The document has to be enabled with Acrobat Pro, as opposed to Standard which cannot enable a document for signatures. This happens automatically when a form is distributed, but you can do it by selecting: Advanced > Extend Features in Adobe Reader
The security restriction summary indicates that signing is allowed because it is, in Acrobat. It doesn't mean it's allowed in Reader.

Signature Field disappears??? %#%^#

I am sure I am missing something simple, I just can't seem to get past it.... I have a form that has a single sub form which works fine, it is visible and invisible when it is supposed to be. The issue however is with the signature field.
I can see the signature field in the design view but not in the pdf view. The signature field needs to be visible all the time and is set to be so, however it disappears in the pdf view. It needs to be visible in case the user desires to sign the form manually and fax it rather than signing it electronically.
Like I said, all the properties on the field are correct, and I can see it in the design view but it disappears in the pdf view and on the pdf form. This form is saved as a dynamic form.
Anyone have any ideas??
Thanks-->> G

while you have the signature field selected go under object-field- presence and make it visible.. unless you have already done that than i have no idea
