Creating a Digital signature

Hi Experts,
I have followed the [SAP Help|http://help.sap.com/saphelp_nw04/helpdata/en/a4/d0201854fb6a4cb9545892b49d4851/content.htm] for creating Digital Signature. In this, they have given the code to sign based on Keystore. There is no option to get the Private Key and mentioning any algorithm for signing. Please help me in this regard.
Thanks in Advance,
Regards,
Venkatesh. K

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.

How to create a digital signature in adobe reader

how to create a digital signature in adobe reader?

Adobe Reader Touch (Windows Store app with "modern" UI) does not support any types of signatures yet.
Digital Signatures with certificates
Electronic Signatures (that are legally enforceable)
Signature annotations (hand-writing annotations which may not be secure and legally enforceable)
Adobe Reader XI (traditional desktop app with classic UI) supports #1 and #3.
Adobe EchoSign supports #2.
Adobe Reader for iOS/Android supports #3.

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.

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.

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

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.

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.

Can't create a digital signature with acrobat 8

We have acrobat 8. My husband has a digital signature but when I try to electronically sign, his digital signature pops up and does not give me the option to create my own. How can I create my own digital signature on this software?

I don't have Acrobat 8, but in Acrobat 7 & 9 it's under "Advanced > Security Settings", which prings up a window where you can add a digital ID.

Unable to create a digital signature

I'm using Acrobat X Pro. The form is great and seems to work perfectly. However I've run into a snafu while trying to create my own digital signature. Using these instructions--http://help.adobe.com/en_US/acrobat/pro/using/WS11dd809af63f0e1e-43e0464b12b4384d3b6-8000. html--to create a new PKCS#12 digital ID file.
(My coworker was able to do it w/o a problem.)
I put in all of the info and then get to the point where it asks for location to save the file and to create a password. Once I create a password and choose Next, I get a box that says my passwords don't match!
This made me think that the system must be trying to match this password with one from a previously created ID but when I went back to manage my digital IDs, none appear in the list.
This should be the easiest thing in the world to do.
Suggestions?

I still haven't figured this out yet.
Is there anyone out there who can help?
I can get as far as the screen where I'm to put in my name, organizational info, email etc but without the Key algorithm and use digital for boxes I cannot go any further and have the process work.
Why would those two boxes be missing from my screen???
PLEASE I really need to figure this out. I have to help over 100 people set up their digital IDs.

Creating multiple digital signatures

When I create multiple freehand signatures in an adobe acrobat document there is an issue.
Can I create multiple signatures and place them on the document without having the original signature be listed as part of an older revision? It marks a new signature as a change to the document and creates a second revision.

>As a business process when would people be approving the other's signatures?
As a normal business process maybe not. But consider: a signature can
have a visual aspect. This visual aspect might be large and not just
an written name: so someone could be tricked into signing something
different than the original document, maybe.
Anyway, this is moot. The signature becomes a part of the PDF. Each
signature certifies the entire PDF, not what a document looks like,
but byte for byte everything in the PDF, whether you can see it or
not. Hence, each signature encapsulates the previous signatures.

How do I create a digital signature using Safari 6.0.3

Just got a refurbished macbook air , awesome, however I am realizing that it doesnt have mountain lion which had the ability to take a snapshot of your signature and save it and use it on docs/pdfs. Is there a way to do this using Safari?
Thanks
