• Acrobat Pro DC - failed to create the digital signature field

  Hello:

  I use a trial version of Acrobat Pro DC and PREPARATION of a form to an existing PDF document. I can't find a way to create a digital signature field that can be "click (to sign).

  Note: The existing .pdf has a digital signature field works but when I click on 'Prepare the form' and select this shape, it blocks every time Adobe Acrobat Pro. I must change the .pdf first, delete the existing digital signature field, save the .pdf, then on 'Prepare the form' and select it with the required signature checked.

  I read several articles in the knowledge base and tutorials that refer to an icon in the toolbar of the digital signature, but I have not this icon can be selected. That's what I see:

  

  When I select the available signature icon (envelope with x) this simply creates a text field, that when the document is opened in Adobe Reader, this field disappears when you click it.

  

  I tried with Adobe Acrobat Pro on Windows 7 as well as currently on Mac OS 10.10.5 (Yosemite). Help to solve this problem would be greatly appreciated.

  Thank you

  The problem is that you have selected the signing required check box. When you do this, it limits you to a form that is compatible with Adobe sign, which allows no digital signature fields. What you can do is to click on the more button in the right panel and select "Back to the form of Acrobat" and you will be able to add digital signature fields.

• Digital signature field

  I can't find the Digital Signature field in MS.

  I have created a form for a client who wants to capture a Digital Signature.

  In the form toolbar prepare there is 'Add a Signature' and 'add a signature block '. I have used these and define the field as "signature", but when I open the form in Reader, the field accepts just plain text. I used before digital signature field and it always comes with the red marker on the ground.

  This option is no longer in DC, or am I missing something?

  Thank you

  What you have done is created a form that is compatible with the services of E-sign of Adobe (Adobe sign, electronic signaturesonline, formerly EchoSign |) Adobe Document Cloud ), which is quite different and incompatible with digital signatures. In form editing mode, select the button "More" and select "Return to Acrobat Form". You will then be able to add a digital signature field.

  Hi - I've never asked a question here - forgive me if I am doing it wrong. I am trying to add a digital signature field in Acrobat DC, so it can be signed to the reader by someone other than me. (A digital step type that DC will draw to you or allow you to draw yourself.) I can do the fields but they do not work. The signature fields used to have little flags in the corner of the box that indicates that they were ready to be signed. My steps consist of:

  Select Tools - prepare forms. I click on the "this document requires signature. Automatic detection is on.

  Next, I check the automatically created fields. I tried to just change the properties of the signature signature box and I also tried drawing signature block or a right signature (not sure what the difference is) , I noticed that under "More" there «return it to the form acrobat.» When I do I get the message that "Acrobat will now NEA Acroform - click ok to continue"-I made and save - can I save again with the new name of 'Save as another' to activate the form. So I check the form in Reader, but it does not work! What I am doing wrong? I used to be able to do that!  I tried other ways, but DC wants me to a digital signature for me (I already have one!) Help please!

  In Acrobat, you can add a signature field to the form:

  

• Language different from the digital signature field

  Hi all

  We use Acrobat 8.1.2 STD and PRO (depending on the user) in our company for the signing of the documents with a digital signature.

  
  Currently I use the German version of Acrobat, and the rest of the description of a digital signature even with switching to English in the field settings 'International' in German. It is not useful since the language of the English ist society.

  However, most of our users prefer to work with their version of the mother tongue.

  Question: How can I change the language of the information in the field of the signature digital in the various Acrobat software languages such as those of our French colleagues, Spanish and German to English by default?

  Thank you very much

  Hi Matthias,

  Cannot change the data encoded in a digital ID. You will need to get a new digital ID before signing if you wanted information signatories to be different. However, if you ask about what the certificate view display, much of this depends on the language of the copy of Acrobat/Reader. For example, most of what you see in the details tab depends on the version of Acrobat. The only thing that would not be strings that are part of the certificate, such as the common name.

• Removal of signatures in a digital signature field

  Hi all, I have a question about the above topic that I hope
  you guys can help me

  (1) is it possible to remove the digital signatures of the form? For example
  If you have a form go through several stages of approval requiring
  signatures and then a step that happened to reject, it would be good to
  remove the previous signatures so that they can be signed again.

  (2) and finally is there a simpler way to combine digital signatures
  and the management of rights, then what appeared in the pdf document provided by
  Duane (second post from the bottom of the thread)? When creating a policy, there is

  a checkbox for "filling in form fields and signing." This forsomething's else?

  Thank you!
  Billy

  (1) is it possible to remove the digital signatures of the form?

  ANSWER: A signature can not be removed ("unsigned") if the system or the user has access to the "private" key used to generate the signature in the first place.  For example, let's say that signs of the user has a PDF file... Only the user can unsign this PDF.  If you were to use LC Digital Signatures ARE to "unsign" a PDF file, you will need to have all the 'Powers' potential user and passwords of credentials stored in the store of approvals for LC would have access to private keys to unsign a signature field.  It's not very feasible if the number of potential signatories.

  (2) at - it a simpler way to combine the rights management and digital signatures

  ANSWER: The combination digital signatures and rights management is not complicated.  You just need to be aware of the "order of operations" required.  Always 'Encrypt' everything first (rights Mgt, certificates and password can be used for encryption) "Certify" (assuming you certify the PDF), then add rights of Extension of the detector (assuming you want to extend the functionality of the document for the reader)

  The reason why the above order is necessary...  When you sign a document, a hash is generated according to the document, if you then encrypt the signed document, you change the document, which in turn a different hash to be generated... This breaks the signature.

  With regard to the "filling of form fields and signing" policy option, it's a 'permission' that you can enable or disable PDF forms with a strategy applied by RM for example, A PDF has a policy applied where the user has 'filling in form fields and signing' andf enabled permission, user B does not work.  A user can open the screen and interact with him by filling and or sign the form.  User B would be able to 'see' the form.  This permission is relevant only with RM in order to protect the PDF Forms.  Also, it should not be confused with the permission of Reader Extensions to allow Digital Signatures in Reader.

  For example, if you wanted a form of 'Certified' must be filled out and signed by the user with Adobe Reader, you will need to:

  Apply a policy to the PDF document where the user has been "filling in form fields and signing" permission enabled, then apply a signature to "Certify" who had permission from "Allow complete and sign form" enabled, then drive to extend the PDF form that allows the authorization of "Digital Signatures" that activates the functionality of Digfital Signatures in the drive for this particular form.

  It may seem complicated, but it's really not

• Digital signature field-how to disable until all required fields are valid?

  I have a document with several required fields, but the user can sign the form without worrying if these fields are valid. Is an option in LiveCycle to control this, IE invalid Signature field until all required fields are true? I think that this could include additional JavaScript. However, I would like to get some advice from others with more expertise.

  Thank you
  Andy

  Hi Andy,.

  Here's a sample: https://acrobat.com/#d=rm5V4y7ANBcmZTsrcXxp1w

  It uses two functions execValidate(), which validates the form and returns true, the form is valid and false if there are errors. PreSign event has access to the cancelAction property, so if there are errors, the cancelAction is set to true.

  I also used the new form Validation features in LC Designer ES2 to combine error messages.

  Good luck

• Adding fields of Digital Signature to multiple Pages in a Document

  Hello

  I have a batch processing java script that will set the fields of digital signature in a drawing.

  Sometimes drawing can contain several pages and the script must set the fields of digital signature on each page.

  The problem with the script that I have is that the digital signature fields appear only on the first page.

  Can someone please provide help to modify my script so that the fields of digital signature are displayed on each page?

  Drawing signature field rev 0

  var this.numPages = NUMPAGES;
  for (var i = 0;  I < numpages; i++) {

  var a = this.addField ("Checked", "signature", i, [1783, 174, 1724, 198]);

  var b = this.addField ("Designed", "signature", i, [1783, 149,5, 1724, 173,5]);

  var c = this.addField ("App Design", "signature", i, [1783, 125, 1724, 149]);

  var d = this.addField ("Proj App", "signature", i, [1783, 101, 1724, 125]);

  }

  Thank you very much.

  You can't have more than one signature with the same name field. In addition, your rect coordinates are reversed, they should look be:

  var a = this.addField("Checked", "signature", i, [1724, 198, 1783, 174]);  // etc.
  

• How do you create field based on signature certificates where you can add a digital signature to the ID?

  During the preparation of a form, it seems that if the field name includes the word "signature", a signature by certificate field is created. If the word "signature" is not present an ordinary field is added which can be signed using fill and sign. I need to know how to create a signature by certificate field (if none is not automatically created) so that the digital IDs can be used to sign the document.

  You can manually add any type of field you want in the form of edit mode. Different field tools are in the toolbar at the top. One of them is the digital signature field tool.

• Prevent the digital signature if the fields are white

  I am just checking that some fields are filled before the user can digitally sign the form. If the fields are empty, I would like to prevent the display of the digital signature window.  How do I do that?

  Here is my script:

  var vSignature
  if(xfa.form.form1.execValidate() == true){
   vSignature = this.rawValue;
  }
  else{
  xfa.host.messageBox("At Least One Required Field Was Left Blank");
  }
  

  Add controls null (or no matter what field validation that you plan to be completed) in the event the digital signature field preSign, if the validation fails then cancel the action after providing a message

  You can attach your form?

• Add the signature field to the second occurrence of two words (nieme Word) on the page

  
  I have a script that searches for two words ("APP ENG") on a page and adds a digital signature field.

  The trick is that there are two occurrences of these words and place the script in the field of digital signature on the first ocurrance of the two words.

  
  I need the digital signature script to add to the second occurrence of these two words.

  There was a counter added the script, but this place then the field on the word ("ENG"), it might have to do with the meter to count one word instead of two.

  
  If someone can help me to modify the script to count the words and the occurrences of two words instead of one word it would be most appreciated.

  Script as follows:

  
  var ckWords; pair of words to test

  var number = 0;

  numWords = this.getPageNumWords (0); number of words on the page

  loop through the words on the page

  for (var j = 0; j < numWords-1; j ++) {}

  get the pair of words to test

  ckWords = this.getPageNthWord (0, j) + ' ' + this.getPageNthWord (0, j + 1); test words

  If (ckWords == "ENG APP") {}

  Count += 1;

  If (count == 2) {}

  var q = this.getPageNthWordQuads (0, j);

  convert quads in the rotation by default user space

  Userspace used by links

  m = (new Matrix2D).fromRotated(this,0);

  mInv = m.invert)

  r = mInv.transform (q)

  r = r.ToString)

  r = r.split(",");

  var m = this.addField ("EngSignature", "signature", 0,

  ([r [0], [1] r, r [2], r [5]]) ;

  }

  }

  }

  Thank you.

  You must use the left coordinates of the first table and the right of the second table.

• Second digital signature invalid one

  Hi all

  I'm having some trouble adding a second digital signature to an already digitally signed PDF file. The library that I use to manage PDF files is open source, so I change the PDF files programmatically. The first PDF I produce, PDF1 (PDF with a signature), has a valid digital signature. The second PDF file I produce, PDF2 (the PDF file with two signatures), has the second marked signature as valid, but the first as not valid with the following error:

  Error during signature verification.  
  Unexpected byte range values defining scope of signed data.
  Details: The signature byte range is invalid
  

  I have read and applied all the "best practices" on the PDF digital signature, so I add the second signature in incremental mode and I am sure that the second PDF has no change in the first part, this is because if I do a binary comparison of PDF1 PDF2, the first part of the PDF2 equals PDF1. So, if you remove the part of PDF2 (after the first %% EOF), you get PDF1, once again, with the digital signature is valid. So the problem seems to be in something again in the part of PDF2 making Acrobat Reader X think that the first digital signature is not valid.

  If you want to see three PDF files, here are the links:

  The original PDF: https://docs.google.com/viewer?a=v & pid = explore & chrome = true & srcid = 0BzrgexS80Iq_ODQxZTY2MDk tNTQyYi00YTE0LTk0MTctYWMxNDFiOWY4MjA5 & hl = en_US

  PDF1: https://docs.google.com/viewer?a=v & pid = explore & chrome = true & srcid = 0BzrgexS80Iq_ZDQ3MTk1ZmI tNWI4NS00YzdhLTkxNmUtODk1NjVmY2M2NTVh & hl = en_US

  PDF2: https://docs.google.com/viewer?a=v & pid = explore & chrome = true & srcid = 0BzrgexS80Iq_ZGM1YmZhMWE tY2JiYi00YzZkLWE5ZjItNzgwM2RlNzExYWE1 & hl = en_US

  Any help will be very appreciated. Best regards.

  Hello

  I don't know if this helps, but I found something unusual with your PDF2. Just at the beginning of the second incremental update (with the new signature), the first object is added without a carriage return. This the last line of the previous update mark looks like this:

  %% EOF3 0 obj

  Perhaps which leads to an incorrect analysis and then invalidates the signature? Not sure on this subject, but as far as I can read offsets, your ranges of bytes are correct.

• Can I exclude the time included with the date in a digital signature for Acrobat DC?

  The digital signature field is a field of area/half which can contain the bit of your own signature image, while the other half contains printed information that are partially customizable via the interface of Acrobat DC:

  

  There that somehow we can exclude the date and GMT (surrounded above)? If this is not possible through regular programming interface, it is possible using an Acrobat API (since Acrobat supports the use of Javascript)?

  Hi rmiranda-applikon

  Yes! You can do the same thing.

  Once you choose to add a Digital Signature in PDF format, click on create a new look... option under label appearance as shown below:

  

  Of the configure Signature appearance that opens dialog, uncheck the option 'Date' and select the options desired, that you want to display in your signature.

  

  Kind regards

• Hide signature field

  Hello

  I work for an application that signs a document and sends it to a remote user via a secure channel.

  Users are complaining that they are unable to see the text or the images because they are masked by the signature. I would like to know if there is a way to hide the signature, so that the user can print or read the document unhindered.

  So far, I only found a way to remove signature (not a valid option for our application). Repositioning of the signature using the programming interface is not viable, because we have no way of knowing what we have in the original document. Repositioning of the signature when the signature is also not possible, because we often originally an already signed.

  I hope that I have my question clearly. Thank you very much

  Hi Ishmael,

  You as the author of the document can create a field that can be signed, but do not print, but if you allow the user to enter a signature on the fly field then the field is printed. It is up to you as the author of the document to create the file the way you want it to look, and if abdicate you this responsibility then you may have what is the recipient of the document.

  It is possible to add a digital signature field that does not print. You control this from the following Digital Signature Properties dialog box.
