Signature in Stamp

Hi,
On a form it is possible to add a signature field, so when a user click on the field they place their signature in that field. Is it possible to do the same in a stamp? i.e. when a user add a stamp they automatically add a signature? Or, after they have added a stamp, they can click on the signature field and then add a signature?
I have made a form where I have a signature field the user can click on that I use as template for my stamp, but it doesn't seem like you can click on a stamp?
Anyone have any ideas, or know if it is possible?
Thanks,
Mattias

Assuming you have a valid license, have you tried to go to the Cisco website and download the latest signatures? And then install them on the AIP-SSM?

Why my signature and stamp disappear with Acrobat Reader DC version ?

I have just install the new Acrobat Reader DC but my signature, paraph and stamp saved in the prevoius version, have disappeared. What is the way to make them back ?

Hi Pascal,
In case is you have not created the back for them before installing Adobe Acrobat Reader DC you won't be able to get them back.

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?

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!

Multiple signatures in a shared review.

Greetings,
I am a tech writer working at an engineering company. I am driving the company toward a digital sign off process for our documentation, and I am using the shared review system in Acrobat Pro X to facilitate this process. These reviews involve 10+ people, and, in the past, the system that was used was to have a single sign off sheet with multiple lines for each representative to sign from their department. I am trying to integrate a similar process into the shared review by adding a modified version of the original sign off sheet into the shared review document that everyone can then sign electronically.
I want to use the signing futures native to acrobat and reader, but I am aware that having multiple signatures on a document is a problem. I don't understand why this feature is not possible in this software. It seems so obvious. Lot's of people have to review it, so lots of people have to sign it.
My Question: is there a workaround that will allow me to do this. I am aware that the stamp tool will allow me to create a custom stamp out of my hand signature, but that method does not time stamp and date it. Having everyone do a timed and dated approval stamp AND a hand signature stamp seems messy and rife with possible errors since most of the people who will be doing this have never used this system before.
Thank you for any thoughts or ideas.

Signature appearance ("stamp" in Test Screen Name's language) in my opinion does have a value. When it is properly generated and applied it does convey information about the signer, time, location, reason, etc. If it weren't in the signature appearance, the document's reader would have to go to Signature Properties dialog to find all these bits of information, and some of them may not even be there if the signature appearance is highly customized. Test Screen Name is totally correct when saying that inexperienced digital signatures consumers may confuse the location of a signature appearance with the part of the document to which the signature allegedly applies.
PDF does allow the signers to sign portions of a document in a limited way. When the first signer signs a document, the signature covers the complete document. When document is modified and more content is added to it and the second signer signs the document, the second signature also covers the complete document but the first signature still covers only the part of the document before any modification was applied. In this case the signature appearance may be indicative of which part of the document this signature covers.
Actually, PDF specification provides for signatures covering only a part of the document (by controlling the /ByteRange entry). It is just that Acrobat (and AFAIK other PDF producers) do not have this functionality.

How do I customize the Digital Signature Reasons dropdown list?

I added a Digital Signature field to a pdf file, then added an Action to the field properties for "Mouse Down" to run a JavaScript.
I am using Acrobat Pro XI.
Here is the Javascript:
// Obtain the signature field object:
var f = this.getField("SigField");
app.alert("ALERT...ALERT...ALERT...")
f.signatureSetSeedValue(
{ reasons: ["Reason1", "Reason2"],
flags: 8
I included the alert statement just to see if the JavaScript is being executed, and it is. The alert is displayed. But, the Reasons field still contains all the default values; it does not contain the specified values ("Reason1", "Reason2"). The name of the digital signature field is "SigField".
Why does this JavaScript not work?
Thank you to anyone who can solve this problem!

A Security Weakness When Signing without a Timestamp

Hi Guys,
I am exploring the need of timestamping PDF documents using Adobe Acrobat wrt security. I see a lot of signatures made without timestamps and I see an issue here mentioned below. If my assumption is valid then Ideally Adobe Acrobat should strongly mandate to use timestamps with revocation information.
The scenario:
A user uses a high trust credential to legitimately sign PDF documents but chooses not to use a Timestamp to avoid costs. These documents have an embedded signature plus the signer’s certificate chain CRLs and/or OCSP responses (but no trusted timestamp).
At a point in time (let’s say 1 June 2012) the credential and PIN is stolen. If the theft is before the end of validity period the credential is of course revoked. However if the theft is of an expired credential it can’t be revoked and most people would not notice and perhaps would not even care. Let us further assume the thief gains access to a number of old signed documents. Of course in theory this is not a problem, because these documents are signed and therefore protected and can’t be changed. However the thief now has access to a range of valid CRLs and/or OCSP responses that were properly valid from before the theft and can use them to their advantage. These documents may even be widely published or perhaps received anyway by an insider thief.
The thief can use the stolen credential and can sign a document at any date/time of their choosing up to 1 June 2012 (by varying their local system date/time) to one that lies within the validity period of any previous OCSP/ CRL data they have captured. Even though the signature covers the validation data this is all done at what seems like a legitimate time.
Trust Threat Analysis:
A stolen credential and PIN can easily be used at a local desktop time (set to anything you like). With PDF editing software – no problem for a hacker of course – you can embed a CRL that shows the stolen credential as good during any period up to the revocation or expiry. The hacker just needs to select a signing date/time that is within a CRL validity period for one of the CRLs they have access to. The selected CRL is then re-used as part of the signing process on a fraudulent document.
It is now up to the receiving software to make the right trust decision – and a trusted timestamp should always be used to make a trustworthy historic decision. If there is no embedded trusted timestamp the receiver software could decide to verify the signature at (a) the current time or (b) the (untrusted) time indicated by the signer. Any software that uses option (b) and trusts the (untrusted) time in the signature rather than defaulting to current time creates a substantial trust issue. The whole purpose of using and attaching a valid, trusted signature time stamp is to independently confirm the accurate date/time of (potentially untrusted) third party signing events. The timestamp cannot be re-used since it covers the signature details. Any substantial variance in time between the signer’s time and the timestamp time is peculiar but systems should always default to trusting the signature timestamp date/time.
Ideally PDF signing software used by a signer that fails to obtain a timestamp should not allow the document to be signed. If the policy is to sign with a long-term signature then the timestamp must be present to confirm the time. Some software products create confusion by allowing the timestamp to be missed if it cannot be obtained. This means that a document that should have a life of several months or years should actually be seen to have an issue immediately after certificate revocation or expiry (could be in a few days or months). Using such software, users will not be aware of the issue until the problem has manifested itself.
Any Comments?

Help with Java script

So , I edited the ITunes.java as described in the Admin guide.Copied the .class to my cgi folder in the server.I copied the itunesu file from the shell folder of the sample code.I have modified it accordingly.But when I run it in browser(Firefox) as ..../cgi-bin/itunesu it just gives me a blank page.Nothing shows up.I ran the ITunes.java file locally and it generates an HTML output, which I copied and created a new html.After I run this HTML file, it opens my itunes, but again it says page not found and url contains https://www.xxx.edu/cgi-bin/itunesu?destination=xxx.edu where xxx is my institution name.Not sure if I am supposed to display my institution name in forum.
The admin guide says on page 15 step 4.Copy the itunes.class file and other itunes file to your web server's cgi-bin directory.
I am not quiet sure what does other itunes file mean??
This is how my .java file looks.

Analysis
The destination string is valid and the corresponding destination item was found.
The identity string is valid and provides the following information:
Display Name my name
Email Address [email protected]
Username mylogin
User Identifier 1243
The credential string is valid and contains the following recognized credential:
1. Administrator@urn:mace:itunesu.com:sites:xxx.edu
The time string is valid and corresponds to 2007-12-03 18:34:33Z.
The signature string is valid.
Access
Because the received signature and time were valid, the received identity and credentials were accepted by iTunes U.
In addition, the following 2 credentials were automatically added by iTunes U:
1. All@urn:mace:itunesu.com:sites:xxx.edu
2. Authenticated@urn:mace:itunesu.com:sites:xxx.edu
With these credentials, you have browsing, downloading, uploading, and editing access to the requested destination.

if(Net >= 0) {Netscape = true}
if(Micro >= 0) {IE = true}
function XYpos() {
if (IE == true) {
xPos = event.screenX
yPos = event.screenY
alert(xPos + " left " + yPos + " down")
else if (Netscape == true) {alert("Script won't work: " + "\n" + "You're using Netscape")}
</script>
Modify the body definition, make sure you have this :
<body #ONLOAD# onMouseDown = XYpos()>
I didnt try it but it make sens to me... tell me if it works!

Can IXOS (OPENTEXT) handle digitally signed PDF documents

Hi All,
we have requirement where we want to store digitally signed PDF documents in IXOS (OPENTEXT) server and view them using IXOS viewer. I have tried to save one digitally sighed PDF but it was also password protected and I was not able to open it with the IXOS live link opener.
Request you to share your experience or views on this.
Thanks a lot.
Best regards,
Vithal

hi,
yes IXOS handlesDigitaly signed PDF documents,
http://opentext.com/download/livelinkdownload.html?path=/corporate/investor/secfiling/FY2005Q4_10K.pdf
Please refere tihis doc..
The repository supports queries based on metadata, full-text index and even a combination
of both. Another option is to render document content to a long-term format like TIFF or PDF. Using
digital signatures (time stamps) it can be assured that content cannot be modified without recognition.
Hence clearly say's retrival or access doc need to enter digital signature which are preconfigured during DOC creation phase.

How do I fix error message "installer file is damaged"?

I have tried to download an application that uses Abode AIR. I always receive the same error message "Sorry, an error has occurred. The application could not be installed because the installer file is damaged. Try obtaining a new installer file from the application author." I have installed, uninstalled and reinstalled Adobe AIR and keep getting the same error message. Does anyone know how to fix this problem?

This usually indicates that the certificate used to sign the AIR install has expired. Based on an archived discussion on this topic, you can search for SignatureTimeStamp in the signatures.xml file in the META-INF folder and, if it is not found, then the install has no signature time stamp and will not install after the certificate expires.
I'm having the same problem, but searching for SignatureTimeStamp is found. The search returns the following:
<xades:SignatureTimeStamp>
So, it would appear that there is a Time Stamp for the Signature in my case so the install should not fail. I would first check the above. Since you cannot install the app, you can try to open up the installation file with the .air extension as a zip file and drill down until you find META-INF and then drill down to find signatures.xml. Search for SignatureTimeStamp and see if it is found.
In the meantime, I was wondering if anyone else in this forum can explain why the install fails for me even though I can locate <xades: SignatureTimeStamp> in the signatures.xml file in the AIR install file.

Curious problem.

Hello.
I have a curiosus problem with a report who uses some functions from a remote server using database link. If I use these functions in SQL*PLUS there is no problem, but if I use them in the report, I get the next error message:
ORA-04062: signature/time-stamp has changed.
I actually work with DEVELOPER 6.0, and the version of report builder is 6.0.5.35.0.
I don4t understand why it works in SQL*PLUS, but not in the report. I suppose that it4s some kind of incompatibality.
Any idea or suggestion will be wellcome.
Thanks.

hello,
this problem is connected to the REMOTE DEPENDENCIES MODE that controls how the PLSQL engine determines if the package-stub has changed.
when you use a remote package/procedure the stub at compiletime of the report is saved in the report. if this stub changes you have to re-compile the report to update the stub. if the remote dependencies mode is set to timestamp, everytime you re-compile the package/procedure the timestamp and therefore the stub chagnes. if it is set to signature the stub only changes if you change the name and/or the arguments (or in case of a package, the package specs).
sqlplus works fine, because if sqlplus detects such a change, it performs an implicit re-compilation.
hope this helps,

I want to sign every page of a pdf

Hello
I have pdf with many pages and i have to sign every single page.
Anyone know, ho to do this ? (in an easy way :-) )

If this is electronic signatures, use stamping.
If it is digital signatures, you do not sign pages, you sign documents; if you believe you need to sign pages you (or your organisation) aren't using digital signatures correctly, and there's a very serious misunderstanding that could remove all benefits of signing and in fact go backwards.

Multiple signatures/stamps in one pdf

Hi there,
I have a pdf document with 50+ pages(drawings) inside.
I am having a heck of a time trying to figure out how to place multiple signatures/stamps (same ones) on multiple pages within that pdf file. Every time i place a signature/stamp, it wants me to resave the document and adds a revision. SO literally, i would have to resave this document over 50 times with 50+ signatured revisions. There must be a less painfull way that makes sense.
All i need is have my stamp appear on selected pages of that pdf file so i can print it out, or send it to a client.
Isnt there a user-friendly way of doing this?
Many thanks,

I do have Acorbat Pro 9, it is a part of CS4.
WIll this still be a legit (acrobat digital signuture wise) stamp?
Thanks,

How to Create a Signature Stamp-Presized

I have been able to create a stamp in Paint, then saved it as a PDF. The initial image was 3.2x1.9 inches. But when I saved it as a PDF, it did not retain it's original size, it blows up to a massive scale. Not sure why, but it feels like there should be a setting to maintain size, almost like scaling, when converting to PDF. Anyways, My work around was to extend the image borders to 8.5x11 inches, and this worked for this item.
Now I want to do the same with my signature, but no matter how I do it or what I change, the image is either its natural small size paint file and when saved as PDF it gets massive or I adjust the sheet, like I did with the other image, and then I end up with the massive block like feature with a tiny signature on it.
Any assistance with this would be greatly appreciated.
I am on Windows 7 pro
Adobe XI 11.0.1
No other image editing options unless done inside Microsoft office apps, besides paint.
Purchasing additional software is not an option.

CtDave, thanks for the excellent write up of instructions. I had to look up a few of those commands as I have never actually used them. But it was easy enough to follow. I followed each step precisely and I was in fact able to create a proper sized signature file. Although, I ran into one issue. The rotation of the signature is 90 degrees relative to how it shoudl be. I have tried rotating the signature in normal and also 90 degrees relative. I have also tried changing the page orientation from portrait to landscape. No matter how I change it, it comes in rotated going vertical. But on the upside, eveything else worked flawlessly. Any chance you have a fix for the rotation issue?
Thanks again for the help.
