How to Start With Digital Signature

Hi Wolfgang,
I open this thread in reference of the discuss in thread
Logon Failed using SSL Client Certificate
I copy the text:
Hi Wolfgang,
Thanks for your quick response...
I don't have very clear what I want to use or which is the best way...I'm still in researching stage...:-) and customer hasn't allready specified what he wants...
We want to research and learn as many as we can to offer to customer the best alternative...
All I know is that customer would need:
- Single sign-on to the system, including SAP systems and Portal
- Digital signing documents.
They work with a local CA called Izenpe (www.izenpe.com) and they give you a SmartCard with your key...
I've found program SSFSDEMO and it works ok: it calls 'izenpe's libraries and sign the document ok. But I find the problem that the moment I call SSFS_CALL_CONTROL function I lose program control... I would prefer customize SAP using SIGNO,SIGNA, ELSIG00, ELSIG01...transactions to allow SAP user to sign or not, but sign with my certificate...
I don't have any external security product to configure...as far as I know customer is against paying for an any other product...
I've tried to sign using SSF* functions but as I've read it only runs to sign in WAS, is it true? it is not possible to sign in local? I allways get signature with server certificate, but not with my own certificate... :-((
What do you think? How do I start? Which is the best way?
Thank you very much for your help!
Regards.

Hello Urtzi,
to build a solution that meets the customer requirements (single sign-on to the system, including SAP systems and Portal, and digital signing documents - all using digital certificates), the customer will need a certified 3rd-party solution. If you want to investigate, you should start with the SAP Software Solution Partner Catalog at [http://sspcatalog.sap.com/catalog/index.jsp], and search for SSO and digital signature.

How to deal with digital signatures when converting messages?

Hi there,
this it not (yet) about the actual implementation. It's more of a logical problem that I'm facing.
There are two partners A and B. A is sending an EDIFACT document which is digitally signed to B.
B has a XI instance that is converting all incoming messages into IDocs, in this particular case INVOIC. This IDoc is received by the R/3 system.
All invoices must be archived due to an eventual tax inspection.
In order to fulfill the security requirements all archived data must be digitally signed.
So far so good.
I guess I'm not allowed to sign my invoices with my own private key due to the fact that i could alter the containing data and sign it again.
It's obvious that I cant apply the digital signature from the EDIFACT message to my IDoc because the data has changed and therefore the signature is invalid.
The only solution to this problem, that I can imagine, is to archive EDIFACT alongside IDoc.
Have you experienced a similar problem or do you have any other idea in order to solve this issue?
I hope my problem is well defined.
Any comment is appreciated.
Thanks in advance
Bastian Stratmann

Hi Bastian,
it is not possible to separate the signature from the document signed.
The system A generates and EDIFACT message -> A has the responsibility on this message and so A sign it.
XI manipulate the message received from A, that means XI generates a new message. -> XI has the responsibility on it, so if you want a signature this should be generated by XI.
As the IDoc was generated by XI it cannot be signed by A (neither technically nor logically) because A has no responsibility on it.
XI <b>is</b> altering the message so XI is responsible for it.
In this case you have to store both the EDIFACT message and the IDOC and maybe sign this new document (EDIFACT+IDOC) with XI signature .
Kind Regards,
Sergio

How to create Web Service Client from wsdl with digital signature?

Please, help me to create Web Service Client from wsdl with digital signature. I know create Web Service client from wsdl file and I know how to add digital signature to XML with jwsdp, but I don't know how to do it together.
Thanks.

I'm handling security wit JAX-WS handler. So I insert "manually" ws-security tag and I encrypt (and sign) message parts.
On client side, all works fine, but on server side I obtain:

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.

Loading Invoice XML IDoc with digital signature via XI into R/3

Hi,
I received an Invoice XML IDoc with digital signature via Mail (for test purposes) and want to load it via XI into an R/3 systeme.
My idea is to load the Invoice XML IDoc file via the File Sender Adapter into XI and send it to the R/3 system via the IDoc Inbound adapter.
Due to the digital signature the file looks like this:
0 S      *H÷
   D0 @   1 0       +      0 '      *H÷
      0 0 û      etc.
When I load the file like this with the File Sender Adapter, an error message occurs in the XI Monitoring as the XML Parser cannot read the file due to the digital signatur (as expected).
Has anybody an idea how I can configure the File Sender Adapter Communication Channel to be able to load only the XML IDoc and ignore the digital Signature strings?
Thanks in advance for your support.
Alex

BTW
do use the second way you need:

PDF with Digital Signatures

I am currently using classic asp and I need to fill out an existing pdf with data from the database. The form also contains two signatures. I just need to fill in the form, save it so I can email it to the the customer. I tried using the fdf toolkit - but my form has text fields that can be 20 characters or 4000. The multiline function in adobe forms isn't working correctly and it cuts it off when you print.
I could create the form in livecycle, and generate the data in xml, but I am so new to adobe, I don't know how to programatically load the file and save it to the server.
I have another program I've tried where I can generate fdf code I think it's fpdf (the php version that was changed to asp) - but I need to know how to generate a digital signature.
I've tried pdftk - I tried to merge the data with the signature - but ended up with permission issues.
I have been working on this problem for several weeks and could really use some help.

Bill,
I'm trying to create a dynamic document using data from the database to generate the pdf, the pdf also needs to containg two signatures for signing. I've looked at every way possible to do this. Currently, my greatest success has come from using the fdf toolkit, but the sizing of the fields (could be 20 chars, could be 4000 chars) leaves me with a very ugly form.
The form I am using already contains the two signature blocks - but I am at a loss on how to populate a pdf form that resides on the webserver with data from the database.
Bill, can you help?

Doc size with digital signature

i've got 2 questions, please help:
1) why do .pdfs with digital signatures have such large file size? how can i reduce the size?
2) why do .pdfs with digital signature become text non-searchable?
thnx
brg

actually the same signature size isn't such a problem when using Adobe software, but when using pdfCreator, the size increases... pls don't give me lectures on using another software, i need A5 and Adobe doesn't provide it...
so i guess it's the problem within that other pdf maker...
why i need to pdf print the file? one reason is i can print it ( otherwise signatures don' show, protection i guess), the other reason to protect the signatures that for that specific reason only need to be seen.
thnx.

Jar files with digital signature -pl help

Hi there
is there anybody who will help me guiding step by step how to create a jar file (executable) with digital signature?
thanks in advance.

Sorry, digital signatures have nothing to do with decompilation security. The short answer is, there's nothing you can do about it. Search the forum for 'obfuscator', a lot of people have asked the same question.

How to start with JDeveloper?

As a straight A student of Computer Science, I put my hands on database development of an information system project for our CS faculty this summer. JDeveloper is used as the IDE for such project.
I have learnt Java 2 and something about Oracle database in my courses. Now, after reading the product introduction and a short online course outline in iDeveloper2001, I have a brief idea about it. But since I can not afford much, how to learn more about it? Could you offer me some advices?
Thanks a lot!

The online users guide and documentation is the best place to
start to learn how to use JDeveloper.

Hello There,
There is plenty of stuff to start with for Adobe Flex. I will
say start searching for tutorials available online & checkout
flex developers blogs.
www.adobe.com/devnet/flex/ is the best resource available,
there are sample applications available along with the code,
different blogs are also listed there.
If you are java developer & have knowledge of Hibernate,
I would suggest start with:
http://blogs.adobe.com/mtg/2006/08/my_first_hibernate_enabled_fle.html
Best of Luck!

How to start with CDC?

Hi, friends:
I have read much online material about CDC, but I'm still confused.
I knew that I can download the WTK2.2 or higher to develop the app based on the CLDC and MIDP.
My question is how to start with CDC. For example, If I use JBuilder, what stuff should been downloaded and installed? and how about the Eclipse?
And some online learning resource is better!
Thanks in advance!

See
http://home.elka.pw.edu.pl/~pboetzel/
for HOWTO run SWT application on PocketPC (emulator). I used CDC 1.1 Personal Profile 1.1. You will find exact instructions what to download and install to write and run CDC applications. And also links to other guides and tutorials.
