Digital Signature - Acrobat 8

I would like to know if it's possible (and if yes, how to) to create more than one digital signature in
Adobe Acrobat 8.
I have several clients and need to be able to sign documents with my various client name / signatures.

Invisible digital signature acrobat x

is it possible to sign a PDF more than once with a digital signature that is invisible? After one invisible signature is on on the page, the invisible signature command is grayed out.

Hi Jay,
There are a couple of ways to go about this. When you are creating the signature form fields, or even later you can edit them, and set the field to Hidden.
You are looking for this:
Another way is to make the first signature invisible using the Sign > Certify without Visible Signature (version 9) or Tools > Sign & Certify > Without Visible Signature (version x) and then clear the signature from the Signature Navigation Panel. Repeat that process for as many invisible signature fields that you need to create. You could then right mouse click on the invisible field in the Signature Navigation Panel and either sign or certify (with the caveat that a certifying signature must be the first signature and a document can contain only one).
Good luck,
Steve

How do I delete a digital signature in adobe acrobat 8 as it has been spelt incorrectly?

A digital signature was created in adobe acrobat 8 professional but has been spelt incorrectly - how can I delete or edit it?

What if you do this:
To delete photos from your device
In iTunes, select the device icon in the Devices list on the left. Click the Photos tab in the resulting window.
Choose "Sync photos from."
On a Mac, choose iPhoto or Aperture from the pop-up menu.
On a Windows PC, choose Photoshop Album or Photoshop Elements from the pop-up menu.
Choose "Selected albums" and deselect the albums or collections you want to delete.
Click Apply.
But I do not think it will work since you can only sync/unsync with one iTunes library and the iPod sees the rebuilt computer as a new iTunes library.
- Do the following to restore the iPod and not lose anything:
- iTunes Store: Transferring purchases from your iOS device or iPod to a computer
- Transfer other music by using a third-party program like one of those discussed here:
Copy music
- If you have synced photos then you need a program like TouchCopy or PhoneView which are paid. They also do music.
- Connect the iPod to the conmputer and make a backup by right clicking on the iPod under Devices iniTunes and slect Back Up
- Restore the iPod from that backup
Note that the backup that iTunes makes does not included synced media like apps and music.

How do I remove a digital signature from Adobe Acrobat Pro. I have set it up wrongly.

I created a digital signature but I wanted to change the signature and it also was not password protected. So I deleted the signature but cannot delete the certificate to set it up again.
Mac OS X (Operating System)
So I am unable to delete the digital signature in Acrobat Xi pro.
I did the following: Adobe | Preferences | Signatures | Creation and Appearance Preferences and deleted the signature. But Adobe | Preferences | Signatures | Digittal ID and Trusted Certificate Settings, does not want to delete.
Tank you.

It's not clear to me what you're trying to accomplish. If you get rid of your digital ID you will still be prompted to create/add one when you need to sign a form, which you say you still need to do? Do you really just want to e-sign (hand-drawn signature, or stamp) instead of digitally sign? Do the forms you're using have digital signature fields?

Adding a digital Signature in Acrobat X Pro

A recent update seems to have altered the digital signature. Before there was no problem and I used the signature I created in Acrobat 9 after upgrading to X Pro. But yesterday (after the update) I was asked for a password for the first time. Eventually I deleted the ID and tried to create a new on but cannot. I follow the steps - a new ID, then a new PKCS#12 file; I fil lin the details requested then on the next page it asks for a file location and password. I accept the default location and type in a password but after the enter I get a message that the passwords do not match.
How do I sole this or am I doing something wrong?

Do you enter the password twice? People have reported that the second password field isn't visible when using a low resolution screen.

Digital Signature crashes Acrobat 9 Pro

An error occurs when trying to Sign any PDF document, even when opening a very simple, one word (Times New Roman text only) PDF document. After opening the PDF in Acrobat Pro (WinXP Pro SP3), selecting Sign, Sign Document, Acrobat allows proper placement of the signature box, and accepts the password for the selected Signature ID. When <Sign> is then selected, Acrobat offers to save the document, and when the save location (any location) is selected, Acrobat returns the error below.
Adobe Acrobat 9.3 has encountered a problem and needs to close. We are sorry for the inconvenience.
Error Signature
AppName: acrobat.exe AppVer: 9.3.2.163 ModName: acrobat.dll
ModVer: 9.3.2.163 Offset: 00135fb9
The same source PDF document can be modified, or password protected, and then saved without a problem. Only when a digital signature is applied does the error occur. Acrobat has successfully Signed and saved documents on this PC previously, but starting experiencing this error about week ago. I have uninstalled Acrobat, reinstalled ver. 9.0 and applied the two updates to 9.3.2, and have generated new Digital Signatures, all with the same resulting error when signing a document. The new, signed PDF document is actually created, and a Digital Signature is found in the document, but is invalid, reporting:
Error during signature verification.
Signature contains incorrect, unrecognized, corrupted or suspicious data.
Support Information: SigDict /Contents illegal data
I have tried the troubleshooting steps in http://kb2.adobe.com/cps/403/kb403613.html, but without any progress; the error continues to remain. Any advice on how to resolve this will be greatly appreciated. Thanks.

Hi Mike,
After the Save As operation was done, did you see the signature appearance displayed in the signed signature field before you closed the doc? And if did see the signature appearance, did you happen to notice if there was a green check mark displayed in the blue message bar at the top of the file?
Thanks,
Steve

Acrobat 9,10 failing to validate digital signature while Acrobat 8 validating it.

I am facing an issue while validating a digital signature. I applied a certified signature with “Annotation, form fill-in, and digital signatures” but
when I apply Redaction “find and permanently remove” on a digitally signed document, Adobe Acrobat 9 and 10 complains that signature is Invalid But Adobe 8 is validating it. I have analyzed that Adobe Acrobat applying Redaction in append mode and original content of signature remains unchanged after Redaction.
Can someone let me know what should be the actual behavior?
Why Adobe Acrobat 9 and 10 failing to verify the signature even Adobe Acrobat keep enable Redaction which means it is allow to apply in a certified signed document with “Annotation, form fill-in, and digital signatures” option.
Prompt responses are greatly appreciated!!

When you sign, you should see where you can select the signature appearance name from a dropdown in the dialog.

PubSec Digital signatures in Acrobat 9

Hi,
i m developing a digital signature plug-in, PubSec, to be specific. My plugin will, hopefully, digitally sign open pdf, and also able to verify them. The signature i am creating will be standard so that any other plugin, including Acrobat's own, can also verify it, and my plugin can verify others too. For this, i will leave the Filter unset and only set subfilter appropriately.
Now, when implementing the signature creation and verification callbacks i found it very difficult, and in some cases am stuck, while getting required information from the provided arguments of the callbacks. For instance, from this structure "PSSigValidateDialogParams" i want to extract information such as:
- signature's verification status
- signer's certificate
- reason location, etc.
But so far i can only get the verification status as:
ASInt32 sigValDigest = ASCabGetInt( sigValCab, PROP_SigVal_Digest, kDSSigValUnknown );
ASInt32 sigValTrustFlags = ASCabGetInt( sigValCab, PROP_SigVal_TrustFlags, kDSSigValUnknown );
ASInt32 sigValId = ASCabGetInt( sigValCab, PROP_SigVal_Id, kDSSigValUnknown );
And i dont even completely understand what each of these mean. And i cannot get the rest of the info from the structure as well, as i cant find any discription about them in documentation. I did find a "Digital signature API Reference" document for acrobat 6, but none for acrobat 9. And even in acrobat 6, there is no description for most of the functions and structure, just the prototype.
Please help me get the above information from the PSSigValidateDialogParams, or atleast point me towards the documentation of the digital signature api reference for acrobat 9. Thanks

Problems getting multiple digital signatures in Acrobat Reader form

I have a Word document that I converted to a form in Acrobat 9 Pro. I added two separate digital signature fields, one for a conference presenter and the other for the conference planner to sign. There are also a number of text fields where presenters give bio information. I saved the document using the Extend functionality so that a user who only has Acrobat Reader would be able to fill in the form, sign/save it, and then send it on to the conference planner. The first part is working fine. However, once the first user signs/saves the document, the extended functionality goes away. When the conference planner receives the document, it is essentially locked. She cannot sign and save.
Is what I'm trying to do possible? I feel like this would be fairly commonplace, but I may be going about it the wrong way. Thank you for any pointers.

Hi Steve,
I have met similar problem. Using Adobe 9.4 I have prepared document with three signature fileds. I did signature in one of the field and then did extension to Reader. When I checked the propierties of document it occured that signing was not allowed. I couldn't sign it second time (not saying of Reader's user).
Is there missing any plug-in or something is wrong with a configuration (mentioned "Nothing has happened when signed" was set up)?

Multiple Digital Signatures in Acrobat 8.1

Hello to all, I am trying to have two people place two (2) digital signatures (using the method: Advance Menu Item | Sign & Certify | Place Signatures) on a PDF document.
There are no problems placing the first signature, but when the second person adds theirs, the first signature ends up having a yellow exlamation mark over the green check mark with the statement: "The revision of the documnet was covered by this signature has not been altered; however there have been subsequent changes to the doucment.".
I must have both signatures showing "green check marks", otherwise my document can be rejected when I submit it. I have version 8.1 of Acrobat and need a solution fast as I need to submit this document tomorrow.
Thanks in advance for any help provided.

I believe this behavior was changed in Acrobat 9.

Acrobat 9 Standard and the Digital Signature usage right

Acrobat 9 Standard is apparently able to apply certain usage rights to a document. I am trying to confirm whether or not the digital signature usage right is included. The
Acrobat 9 product comparison seems to indicate it is not, but the online help implies that it is.
Can someone with Acrobat 9 Standard confirm this for me by testing a document that you've enabled for use with Reader by attempting to sign a digital signature field with Reader?
George

In the office area, the Pro version might be good to have for the forms and other features. For the general library, Reader is probably adequate. Actually allowing PDF creation on public machines can be an issue. In a small libary system, Acrobat might be reasonable where you do not have to deal with a large, diverse population. However, for basic PDF creation, only Std is needed. Having both AA8 and AA9 on the same machine can lead to problems. However, if you remove one, you will likely have to repair the other.
The problem with older versions is that they may not properly read some of the newer PDFs that might be downloaded. For the latter, you could install the latest version of Reader, but you need to be aware that you may have to deal with issues of right clicking (windows) on a file and selecting which application to open a PDF with. For forms and some editing, the Pro version would be good to have. You also have PDF Optimize and PreFlight with the Pro version that generally are not including in the Std version.
To help compatibility with the files you create, you can select Start>Printers>Adobe PDF preferences (right click on printer). In the settings tab>Default settings> select at least Std or better Press or Print and then push edit. Under the general tab select the compatibility and set it to AA8 so that every thing is compatibile with the oldest version of Acrobat you have.
If you have more than one computer in the office, you might consider having AA8 on one and AA9 on the other. Do check and be sure you have licenses for whatever you have and that someone has not come in and installed a pirated version. Also be sure you keep the original CDs and licenses (or if they were downloaded, burn the downloaded version to a CD as an archive and write the SN on the label).
Now that I have confused you, are there more questions?

Digital Signature not allowed Acrobat 9.5.2

I created a form in Acrobat Pro and saved with extended functions. I'm using Acrobat Standard 9.5.2 which allows me to add digital signature. Most other employees can add signatures as well. However, there are a couple (using the same version software above) that when they open the file the security for digital signature is set to "Not Allowed". When I open the same document signatures are allowed. Therefore, is appears their software settings is setup differently than everyone elses. Can you help identify which setting needs to be changed?

Classification: For internal use only
I can't attach images at this point. The security method for both is No
Security. However, on the other user computer next to signature it states Not
Allowed. However, when they open the same form they see an error on top that
does not show up when I open the same form. The error message is, 'At least
one signature has problems. Please fill out the following form. You cannot
save data typed into this form. Please print your completed for if you would
like a copy for your records'. However, when I open the same for I do not get
that message. It almost seems like a security setting within their reader or
not.

Appearance of Digital Signature in Adobe Acrobat 8

I am creating a digital Signature in Adobe Acrobat 8 and am having difficulty getting all the information to appear clearly. The first example below shows, the signature, name and date. I would also like to include the name of the Company. The only way I have been able to do that is by clicking the “distinguished name” box in the appearance section of the digital signatures. An example of this signature is also shown below. However, additional information such as the name (again), email and country are also being listed. There are numerous abbreviations and equal signs now appearing as well. Ideally I would like the signature to look like the first one with the company name appearing just above the person’s name. Can anyone help me do this?
Thank you!

Hi,
For the first problem (word wrap). The problem you are encountering is if "Maryanne Doe" is too long to fit in half of the signature field, the text wraps to the next line. The signature appearance that is written into the signature field consists of two halves. The left half contains the graphic properties and the right half contains the text properties.
You need to lengthen the width of the area where the graphics portion of the signature is contained. You can do this one of two way. Either lengthen the physical dimensions of the signature field before you sign. Or, you could create a custom signature appearance where you turn off all of the text properties, which has the effect of giving the whole signature fields over to the graphics portion. To play with custom signature appearances:
Select the Edit > Preferences (Win) or the Acrobat > Preferences (Mac) menu item
Select Security from the Categories list box
Click the New button in the Appearance group box
If you select the No Graphic radio button you give all of the space to the text portion. If you deselect all of the checkboxes in the Configure Text area, you give all of the space to the graphics portion.
While you are in the Preferences dialog, select Identity from the Categories list box. Go ahead and fill in all of the editable fields. This is where the data is procured during the creation of a self-signed digital ID. I think that will fix the second issue you raised.

How do I remove the digital signature option on Adobe Acrobat 7.x? I don't want it, but it pops up every time I need to sign a form, and I cannot find a way to remove

I created a digital signature to sign forms using Adobe Acrobat 7.x. I really don't want or need this feature, but do not know how to remove it or keep it from popping up every time I need to sign a form. Can anyone help? I'm not that technically savvy, so please explain in layman's terms. Thanks!

It's not clear to me what you're trying to accomplish. If you get rid of your digital ID you will still be prompted to create/add one when you need to sign a form, which you say you still need to do? Do you really just want to e-sign (hand-drawn signature, or stamp) instead of digitally sign? Do the forms you're using have digital signature fields?

I need to verify that Acrobat Standard XI has the ability to add a digital signature form field to an existing PDF file.

Can anyone answer this question for me?
As in, a PDF that has already been created in a different version and has established form fields. Can I open it in Standard and add a digital signature to a field or do I have to use Pro, or does the form need to be recreated? The comparison chart is kind of unclear about this.

Yes. It was possible in Acrobat X Standard and I do not think it was removed in Acrobat XI Standard. It does not matter with which version your PDF was originally created. You can always add fields.
