How to create a digital signature error

Hello,
hope i do my post in the right forum (if not i'd be grateful if it could be displaced to the correct forum). I've to do create some incidents to have a look at the output of Security Audit Log (Transaction sm20).
I want to create a digital signature error (SAL Identifier AUV) and i've no clue how i could get it done. First I thought about an invalid single sign on ticket but apart from I would have no clue about how to create such, I don't know if that's a way to make the error, mentioned above, occur.
Maybe you could give me a hint or you have an idea how I could get that done!?
Thanks in advance
Tobias

How to get verified digital signature for applets?

Hi All,
I run a small website with an applet ( [http://www.tozsdeasz.hu/grafikonrajzolo/inditas.html|http://www.tozsdeasz.hu/grafikonrajzolo/inditas.html] ). Visitors can load files into the applet, so the applet needs to ask for permission from the user to access files on the visitor's computer. When doing so an unfriendly window pops up telling that the digital signature of the application cannot be verified (you can see it for yourself by the link). Some users keep complaining about it fearing of the security risk.
What is the proper way of getting a properly signed applet? (how to get a verified digital signature?)
Please help me!
Best wishes:
Szabolcs Kelemen

Thanks for the links.
As far as I saw in the documents I need a "digital certification authority" to sign the jar.
Do you know any of these authorities that is free? The entire application does not worth much, I can't afford expensive certifications.
Best regards:

How do I create a digital signature on a TCP or a UDP flow?

I am trying to convert samples of a voice signal, which is intercepted from the microphone, into fixed length digital signature bytes (using Hash, or) and attach these fixed length bytes to a communication session between two terminals (UDP or TCP "HTTP"). The other receving end should be able to identify the person at the sending side.
Any thoughts how I could do this?
Any help is most appreciated.
Sam

Sam,
If you have the Sound and Vibration toolkit it may make some things easier for you regarding the voice-recording aspect, but if you aren't recording and playing back the actual sounds, just using this for detection and digital signatures, you shouldn't need to worry about this.
1. For this you are going to be doing some form of Analog Input. Then you will be storing this data to a file. There are examples for both of these aspects in the NI Example Finder from within LabVIEW.
2. If you are going to be doing the FFT, there is a VI under the Mathematics Palette that performs this operation. Again you can use the same example for saving data to the file.
3. You would need to figure out what needs to be done to create a digital signature for this. There may be something in the Sound and Vibration toolkit for this, but I do not know.
4. For the UDP or TCP transfers, there are several examples for doing this and they cover how to create the connection and transfer / receive data. These too are in the NI Example Finder
5. This goes back to number 4, this would indeed be a separate program, but everything else would just be one project and one program.
6. This would depend on how the ID was created in step 3, again whether you do the algorithm on yourself or not. For comparing to the table, you would use a Search Array and some comparison functions, all depending on how you stored the data initially.
7. Graphs are all available on your Front Panel of your VIs and you would just wire up the data that you'd like and have it displayed on the graph.
There will not be an example for everything that you are wanting to do. The examples are meant to help you get started. Have you used LabVIEW before? I would recommend doing the 3 Hour LabVIEW Introduction Course to help you get started. This will cover some of the basic concepts that you will need to know in order to create your application.
Unfortunately I cannot write the code for you, only guide and direct you. LabVIEW is a programming language and does require the user to lay out and create their own program. You will not be able to just find three or four pre-built code-snippets and connect them together to get your appliction working the way you want it. You will need to develop the applications yourself.

In Adobe X Pro, how do I create a digital signature in my document so that my receiver is able to sign it electronically.

In Adobe X Pro, how do I create a digital signature in my document so that my receiver is able to sign it electronically.

If the other person will be using Reader, you should first add a digital signature field and then Reader enable the form. In Acrobat 10 you'd select: Tools > Forms > Edit
to get into form editing mode. You'd then select the signature field tool to add a signature field.
Once you have the document finalized, Reader-enable the document by selecting: File > Save As > Reader-Extended PDF > Enable Additional Features
being sure to save to a new file so you don't overwrite the original. If you don't Reader-enable, Reader users won't be able to digitally sign.

I was able to create a digital signature for someone else and use it. How is that protected??

I was able to create a digital signature for my boss who's on vacation using his email address. I figured when I used the signature he would get some sort of email confirmation letting him know, but he got nothing. So it seems like I could create a signature for anyone and use it on any document without their knowledge. What's the protection against anyone creating a signature for anyone else and using it whenever?? Am I missing something??

A digital signature can not be used to verify someone's identity. I can create a signature using anyone's name and email address. In fact, those things are irrelevant to the signature. The only thing that matters is the key used to create it, and therefore to verify it.

How to create a frame in a applet?

Dear All,
How to create a frame in a applet?
Thanks in advance
Kityy

You can't add a Frame/JFrame to an Applet/JApplet.
An Applet/JApplet has its origins in the class Panel/JPanel.
So, if you make your Applet to an application you
can easily do that by putting your Applet "above" a Frame.
Maybe you can archieve your goals with some Panels?!

Create electronic-digital signature for data

Hello
As possible create electronic-digital signature for data, referred through HTTP form internet explorer?
Thank you very much for your support.

George,
Thank you for your submission. It was helpful. This allowed me to create the signature block without having to place my own digital signature in the block. However, when I send it to my client (who has Adobe Reader but not Acrobat) she is unable to input her digital signature … I’m now half-way there but I continue to pursue a solution.

Problems Creating the Digital Signature

Hello,
I'm using php 5.2.4-3, apache 2.2.8-1 on Fedora 8 and I'm trying to test out my authorization to iTunes U but I'm having difficulty creating the digital signature.
Does anyone know of any PHP implementation/script that I can use to create the digital signature?
And I don't quite understand the 3rd step "Convert the HMAC-SHA256 output value into a 64-character hexadecimal representation". Does this mean chopping off the right most characters till it's 64 characters?
Thanks for any assistance.

Hi, Could you please post the php file you've found? I'd really appreciate it. Thank you.

How do I create a digital signature to use when filling out applications online?

The application is asking me to add or create a digital ID to sign and encrypt documents. The certificate that comes with your digital ID is sent to others so that they can verify your signature.
I have four options: Browse for an existing digital ID file
Configure a roaming ID for use on this computer
Create a self-signed digital ID for use with Acrobat
Look for newly inserted hardware tokens

Formscentral does not support forms with digital signature workflows. I suggest you see if our Echosign product meets your needs.

XMAM30 - digital signature - new applet running with MobileEngine.exe

Hello,
I am new to this forum and could not find a solution for my problem.
I would be very happy, if anybody can help me.
I have developed a new applet based on the standard SAP applet for the digital signature in xMAM30. This applet works fine in Microsoft Internet Explorer 6.0 but it doesn't work with the MobileEngine.exe!
I have already read the SAP note 897289 about this topic, but this note was not the solution for my problem. Because the SAP Standard applet (com.sap.mbs.mam.order.control.SignApplet) in the mamsignapplet.jar works fine in MS IE 6 and with MobileEngine.exe.
After several tests I found out, that the problem must be the JAR-file which contains the applet.
I have created a new JAR-File of the SAP applet class: com.sap.mbs.mam.order.control.SignApplet with the same MANIFEST.MF which I found in mamsignapplet.jar. But this new JAR-file doesn't work with MobileEngine.exe. Only the MS IE 6 could load the standard SAP applet for digital signature.
Now my question is:
What is the difference between the standard SAP jar-file "mamsignapplet.jar" and the jar-file I have created by using the normal Eclipse export as jar functionality?
What's wrong with the jar-file I have created?

Hello,
The jars have to be "digitally signed". You can have a look here:

If it is still not wroking, I can find out with the production guys how they do it.
Thank you,
Julien.

How to do Multiple digital signatures?

I have created a form in Acrobat 9 Pro with multiple digital signatures. This is an approval form that is emailed "up the chain of command". I have enabled extended features in Adobe Reader so that users without Acrobat 9 can digitally sign the form. I created the form and did a certified signature. I then emailed it to a typical user who filled in the form and emailed it to her boss for a digital signature. Her boss digitally signed it and emailed it to the CFO. The CFO does not have Acrobat 9. When she gets it, she gets the error message "This document enabled extended features in Adobe Reader. The document has been changed since it was created and use of extended features is no longer available. Please contact the author for the original version of this document." How do I correct this?

Steve,
I wanted to test how cumbersome it would be to have the 2 staff members open with Adobe Reader instead of Creative Suite; however, I have not been able to find any option like "open with" in my outlook email. Every time I try to open it defaults to my Acrobat 9 Pro to open the document. Would the 2 staff members have to save the email and then use "open with" in order to by pass Creative Suite?
Also I am not sure if you answered my question last time - Is it possible to just upgrade the Acrobat portion of Creative Suite or do you have to upgrade the entire Creative Suite just to get the newer Acrobat? I will also be checking the upgrade link you sent. Thanks.

How to verify the digital signatures?

Buyer has to send a certified interactive form to vendor, vendor has to digitally sign the form back. We need to verify the signature of the vendor only then start processing the form. How do I achiev this security.
1) How do I generate buyer certificate and attach to the form.
2) I have created a signature field in the form, after the vendor signs it how do we check whether its the correct signature?
Kindly specify the steps.
Helpful answers will be rewarded.
