Generating digital signature

Hi,
I want to use digital signature to develop some application. It is for experimenting purpose. So is there anyway to generate digital signature without involving CA??
Thanks

You could use the keytool program that manage a key store, which is a database of certificates. To do so, use the command line:
keytool -genkey -keystore yourKeyStore.store -alias yourCertificate, then follow the instructions. The keytool command allows you to import/export certificates, etc. Just type keytool on the command prompt and you get all the options.

Using the AutoText Feature: An easy way to generate Digital Signatures

One feature I find particularly useful is "AutoText".
Using this, you can assign a keystroke combination to effectively generate a word, phrase or sentence while typing messages on your blackberry.
This is a great tool, particularly for multiple digital signatures across several email addresses, text messages and also to use with apps like Facebook and Twitter.
To access the "AutoText" feature, begin a new email or text message, hit the "Menu" button and select "Edit AutoText".
A list of all the stored abbreviations is displayed.
Simply begin typing the set of keystrokes you want to associate with your digital signature (or any other word/ phrase/ sentence etc.) and you will see the current abbreviations associated with those keys.
Type in a unique set of keys you want to associate with a series of words and hit the "return" or "enter" key.
A new screen with the following display will appear:
"Replace:
With:
Using: SmartCase
Language: All Locales"
In the "Replace:" section, key in your own abbreviation and the associated word or words in the "With:" area.
Pick the options from the "Using:" and "Language:" drop down menus and you're done!!
Hit the "Back" key and select "Save" from the dialog box which appears.
Now, use the keystroke you just created while typing messages and see how much easier this wonderful feature makes your life!!
Trust this tip is valuable to you all. I'm not the best writer in the world so if anything here is not clear, please ask and I will clarify to the best of my ability.
Best.

Thanks for your write up. Indeed autotext is great way to simplify your signature or commonly used templates for SMS or emails.

How to get digital signature for Google Map geocoding V3 in PL/SQL?

Hi, Gurus:
    Could anyone provide me an example about how to generate digital signature for Google Maps service v3 in PL/SQL? We tried to upgrade our program using Google maps service from v2 to v3. We are using PL/SQl on background to send request to Google for geocoding. We found some sample code to register with digital signature, but none of them is based on PL/SQl. Notice I used Google business client ID "gme-XXX" and wallet.
https://developers.google.com/maps/documentation/business/webservices/auth#digital_signatures
Google Maps API - more URL signing samples
Here is my code for V2. I notice in order to get signature, I need to use HMAC-SHA1 algorithm.
procedure Get_Geocoding(P_s_Address in varchar2, P_s_Geocoding out varchar2, P_n_accuracy out number, P_b_success out boolean) is
l_address varchar2(4000);
l_url varchar2(32000);
l_response varchar2(3200);
n_first_comma number;
n_second_comma number;
n_level_length number;
BEGIN
/* TODO implementation required */
l_address:=APEX_UTIL.URL_ENCODE(P_s_Address);
l_address := replace(l_address,' ','+');
l_url := 'http://maps.google.com/maps/geo?q='||l_address||'&'||'output=csv'||'&'||'client=gme-XXX';
l_response := utl_http.request(l_url, APEX_APPLICATION.G_PROXY_SERVER, '/u02/app/oracle/admin/apexsb/wallet', 'XXXXXXXX');

n_second_comma:=instr(l_response,',',1,2);
n_level_length:=n_second_comma-n_first_comma-1;
P_n_accuracy:=0;
if n_level_length>0 then
P_n_accuracy:=to_number(substr(l_response,n_first_comma+1, n_level_length));
end if;
l_response:=substr(l_response,instr(l_response,',',1,2)+1);
--dbms_output.put_line('In function: l_response ='||l_response);
P_s_Geocoding:=l_response;
if (P_s_Geocoding<>'0,0') then
P_b_success:=true;
--dbms_output.put_line('true');
else

Install Digital Signature on PDF Generator - Turn Key installation?

Hi,
I use TurnKey installation to install PDF Generator ES already. It works fine and it is in production line. Now I need to install Digital Signature ES. Can I use turn key installation? I suspect if I am doing so, the Jboss/MySQL will get overwrite and the perevious PDF Generator ES installation will be messed up, right? Any recommedention under this situation how to install Digital Signature ES?
Thanks a lot.

Hi,
I believe the correct approach will be to run the configuration manager, and simply add your key for DS, and go through the configuration. It shouldn't destroy your PDF G installation.

Using iText to generate a digital signature that can be signed in Adobe Reader

I am able to create a digital signature in a pdf using iText. Adobe Reader does not allow that digital signature to be signed. Everything I have been reading suggests that I need to enabe Reader Usage Rights, but that requires using Adobe Pro. I was hoping that I would only need Adobe Reader inorder to digitally sign the pdf, is that possible?

Not without the required rights...

Digital Signature on pdf Invoice generated by BI Publisher

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

Issue with multiple digital signatures disabling fast web view

Hello, I'm using acrobat 9.1 pro and have some questions regarding an issue using multiple signatures on a pdf.
Why am I asking the question below? My job involves preparing pdf's for submission to FDA. The FDA requires, among other things, that electronically submitted docs have fast web view enabled.
I am currently exploring ways of using digital signatures to sign pdf reports and still make sure they are FDA spec compliant. My issue involves a document that would have multiple signature fields. What I do is create at least two signature fields in the doc and then save and optimize while enabling fast web view. When I sign the first box and save, the file retains the fast web view status. Yet, when I apply and signatures past the first one, the file is subsequently set to fast web view off without any obvious way of turning it back on. I am confused as to why it gets disabled only after the second, and not right after even the first one was signed. And, of course, I would like to know if it is possible to maintain fast web view and how to do it. I'll gladly accept "tinkering under the hood" of the file suggestions if they exist as well.
Please let me know if anything is unclear or you need further information.
Thanks for your time and help.
~Vlad

Hi Vlad,
Michael actual had the correct answer. The purpose of a "Linearized" file (i.e. a file that has been Optimized for Fast Web View) is to get the first page to display as soon as possible so you can start reading without waiting for the rest of the file to download. As an aside, the designated first page doesn't necessarily have to be page 0 (PDF's use a zero based counting system for pages), but usually it is. To quote the PDF specification, "The primary focus of Linearized PDF is optimized viewing of read-only PDF documents. It is intended that the Linearized PDF be generated once and read many times. Incremental update is still permitted, but the resulting PDF is no longer linearized and subsequently is treated as ordinary PDF."
When you sign a PDF file the first time the Save process is a "full save", that is the entire document is rewritten so there are no more than two %%EOF (end-of-file) markers in it. The first EOF designates which page to show first and the second EOF designates the end of the rest of the file (so the browser knows when to stop downloading). However, when you add a second (or subsequent) signature the file is saved as an "incremental save" and all of the new data is tacked onto the the end of the original file. This is so you can do a rollback to the previous signed version and allows Acrobat/Reader to check the integrity of each signature independent of any other signatures. It's the incremental save that breaks the linearized optimization of the file.

How to Create a PDF Document and apply Digital Signature in C# using the Adobe SDK?

Hi Everybody!
I have to do two distinct tasks here:
1) How can I create a PDF document using the Adobe SDK in my .NET Applications(C# - 2.0)?
I just need a basic sample to create a document with a simple text, for example. I did not find any useful information in the adobe documentation. I have the Acrobat Professional 8.0 in my computer, but it's very dificult to work whith de Acrobat.dll and .NET with a poor documentaion.
2)How can I apply digital signature in a existent pdf document?
I need to sign documents using the SDK, just a basic sample in c# would be helpful to start!
Anybody could help?
Thank in advance!

Leonard Rosenthol or anybody that can help, sorry to insist.
I will explain better my problem:
I have an ASP.NET WebPAge (C# - 2.0). In this page, the user make a request. The request should generate a PDF document with the informations of the request and with a field to add a digital signature. The document created will be send to a approver that will confirm the approval applying his digital signature (I need to do too, a webpage where the approver open the page, choose the pdf document, and sign, just selecting his own certificate and clicking in the button SIGN... but this is another problem).
That's the reason that I have to create a PDF document. If I create a WORD or HTML document, and then convert to PDF, how can I add a field to digital signature in this pdf document?
Is there any solution using Acrobat SDK?
Thank you very much!

How does the LiveCycle Digital Signatures work?

Hi,
I´m new working with liveCycle, and I would like to know how it works at technical level.
I have read documentation but I can not understand the procedure to generate the digital signature
I appreciate someone explain a bit about it or send a link to a page with detailed information.
Thank´s!

Your question is pretty broad...
What are you trying to achieve with your workflow? For example, do you want to...
Generate Digital Certificates (self-signed or otherwise)
Have end users digitally sign PDF document or forms (with Acrobat Pro or Reader)
Have the PDF document or forms digitally signed on the server side
Validate the digital signature on the client
Validate the digital signature on the server side
I have attached a document that should help as well.

Security Issues: SSL on SOAP Adapter and Digital Signature in BPM

Hi there,
we're developing a R/3-XI-3rd Party Application scenario, where the XI/3rd Party communication is based on a webservice (SOAP adapter with SSL). Also, the messages in the XI/3rd Party communication must be digitally signed. I've got some questions on both subjects.
1. About the SSL. I've started to investigate what will be necessary to enable the HTTPS option under SOAP Adapter (it's not enabled now). If I'm not correct, all I need to do is:
- check whether the SAP Java Crypto Lib is installed in the Web AS;
- generate the certificate request in the Visual Administrator and, after acquiring the certificate, store it with the KeyStorage option.
Is that right?
I'm considering that I won't need to use SSL in the ABAP Web AS, only the J2EE Java Engine (since the SOAP Adapter is based on J2EE).
2. About the digital signature. As a first solution, we had decided on accessing a webservice based on another machine running a signature application. We'd send the unsigned XML and receive a signed XML. But since that needed to be done into the BPM, I thought that using a piece of Java code in a mapping would suit it better.
But to be able to use the hashing/encrypting/encoding algorithms, which library needs to be installed? Is it the same SAP Java Crypto Lib that was installed for the SSL enabling?
Thanks in advance!

Hello Henrique,
1. You're right. For detailed instructions please have a look at the online help: http://help.sap.com/nw04 - Security - Network and Transport Layer Security - Transport Layer Security on the SAP J2EE Engine
2. The SOAP adapter supports security profiles. Please have a look at the online docu http://help.sap.com/nw04 -Process Integration - SAP Exchange Infrastructure - Runtime - Connectivty - Adapters - SOPA Adapter - Configuring the Sender SOAP adapter and from the link under Security Parameters to the Sender Agreement. You'll find some additional information in the following document: http://service.sap.com/~sapdownload/011000358700002767992005E/HowToMLSXI30_02_final.pdf
