Implementing Digital Signature Strategy In Adobe Forms

Hi Everyone,
I need to know how to implement Digital Signatures with the use of Signature Strategy in my ECC 6.0 system..
Here is what i've done already,
1) Created a signature strategy with user authentication and registered the Signature Object in TA_SIGNO according to the document below.
[http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/e0fbaa71-cd8d-2910-5982-e30626035400]
2) I have Adobe Acrobat 9.0 already.
3) Now, Ive added a Document Signature Field in my Adobe Form Layout too.
4) How to implement the Signature strategy i've created in this Adobe Form ???????????
Kindly share your ideas.

Hi,
maybe the reason for this is that the status of the digital signature is not changed. Then the system thinks that the digital signature is still completed and therefore the user is not getting the pop-up again. The database table for the digital signature for documents is TC77. I hope this information is usefull for you.

Hi, I am oracle apps HRMS Technical consultant.I wanted to know ,can we implement Digital Signatures in Oracle apps 11i XML Reports.if yes what is the approach to do so ? Your quick response is appreciated. Regards , Aasma Sayyad.

Hi,

Hi Aasma,
The standard BI Publisher is part of EBS applications.
Most of the EBS reports(R12) are based on BI Publisher.
If you check the responsibility 'XML Publisher Administrator' you will see all the templates used in the application.
Your technical team should already know this.
On the other hand OBIEE would need separate licences.
But for you BI Publisher would do.

Hi ,
If you wish to use your own texts/mono/signatures when outputting a purchase order, proceed as follows:
1. In the step Adjust Form (Layout Set) for Purchasing Documents, check to see at which points you can store your own texts in the standard form MEDRUCK.
2. Enter the texts in accordance with your requirements using the SAPScript editor. To do so, choose SAPscript Standard Texts.
Assign unique names to your texts (e.g. names containing the key for the purchasing organization).
3. Choose the desired text type (e.g. texts for document item) under Document Printout: Purchase Order.
4. Create a new entry and enter the following data for it:
Print operation (e.g. new printout or printout of changes (change notice))
Purchasing document type and item category
Text object, text ID and the text name
Print sequence in which the text is to be outputted
In the standard system, the purchasing form is called "MEDRUCK". MEDRUCK is a multi-purpose form controlling the output of RFQs, POs, outline agreements, delivery schedules, reminders/urging letters, rejection letters, change notices, and order acknowledgment expediters.
Changing the Purchasing Form
Prerequisites
Before you make any changes to the standard form, you should consider the following.
Change Existing Form or Create New One?
You can either change the standard form or create a new form by copying the standard one.
When you change the standard purchasing form, you must first create a correction number, because changing the standard form represents a customer modification. Thereafter, the system maintains both your changed version and the SAP version of the form.
If you create a new form, you must assign it to the appropriate message type (PO, rejection letter, etc.) before the system can use it for printing.
Its recommend that you always create your own form. This makes it easier to distinguish between your customized form and the standard form provided by SAP.
Hope ths helps
please reward points

Need help with implementing Digital Signatures

Hello,
Here's an excerpt from a security book:
To create a digital signature, a sender first takes the original plaintext message and runs it through a hash function.
The Secure Hash Algorithm (SHA-1) is the standard for hash functions.
The hash value is also known as a message digest.
Next, the sender uses the its private key to encrypt the message digest. This step creates
a digital signature and authenticates the sender, since only the owner of that private key could
encrypt the message. The sender encrypts the original message with the receiver’s public key
and sends the encrypted message and the digital signature to the receiver.
The receiver uses the sender’s public key to decipher the original digital signature and reveal the message
digest. The receiver then uses his or her own private key to decipher the original message.
Finally, the receiver applies the agreed upon hash function (e.g. SHA-1 or MD5) to the original
message. If the hash value of the original message matches the message digest included
in the signature, there is message integrity-the message has not been altered in transmission.
I would like to implement the sender's part and create an encrypted message and the digital signature.
Suppose I have in hand a message (let's call it myMessage), my private key (let's call it myPrivateKey) and the receiver's public key (let's call it receiverPublicKey).
In order to encrypt the original message with the receiver’s public key I've implemented this piece of code:
Cipher cipher = Cipher.getInstance("RSA");
cipher.init(Cipher.ENCRYPT_MODE,receiverPublicKey);
byte[] binaryCryptData = cipher.doFinal(myMessage.getBytes());
String encPayload = Base64.byteArrayToBase64(binaryCryptData);
return encPayload;In order to create the signature I've implemented this piece of code:
Signature RSA = Signature.getInstance("SHA1withRSA");
RSA.initSign(myPrivateKey);
byte bt[] = message.getBytes();
RSA.update(bt);
byte[] signature = RSA.sign();My assumption is that I don't follow the exact guidlines in the book for the sender.
Can someone please let me know what I'm missing and help me in adjusting my code with the books standards?
Thank you in advance,
Roy

it's your homework, not ours.
Congratulations on typing in everything BUT the most important part that it's all about, but that's not enough.

Need help making digital signature field read only if required fields are null

Using Adobe LiveCycle Designer, I have a digital signature field. I want to prevent users from being able to digitally sign the pdf if any required fields in the pdf are null or blank. I'm a newbie to scripting so any detailed help would be greatly appreciated. The required fields in the pdf include radio buttons, check boxes, text field, etc. I appreciate any help anyone can provide.
Thanks

Exactly how you check a field for being empty depends on what type of field it is. For text fields, you should get the field's value as a string and compare it to an empty string, something like:
var val = getField("Text1").valueAsString;
if (val) {
app.alert("Field is not empty");
If there is a default value that needs to be changed, you would compare to the default value:
var f = getField("Text1");
var val = f.valueAsString;
if (val !== f.defaultValue) {
app.alert("Field value is OK");
For check boxes and radio buttons, you'd compare to the string "Off", which means none in the group is selected.
For dropdowns (combo boxes) and list boxes, there is normally one value selected, so you would have to get the value and check against the default value (or something else) to see if the field is properly filled in.
You could place the script there, but I usually use a separate button that I encourage the user to click in order to check the field. The problem with using the Will Save event is you can't prevent the save from happening.
The script can loop through all of the fields (and test all required ones), or you could set up an array of field names to check.

Need help with Digital Signatures Please

HI Folks,
This is probably a really ignorant question but.....I have
users who download packaged files to run on their own PC. Have run
into the problem of the security warning - Publisher could not be
verified....and providing the choice to run, or cancel the file.
Suggestions?

Need Help Locking Digital Signature Field

I am working on a form with a number of sections to be completed by various departments. When a section is completed, I have a digital signature set to lock the fields related to that section. The form is sent to the next department and so on… Locking the form fields with the digital signature works just fine. The problem I have it that when viewing the form in Acrobat 8 Pro, the digital signature can be right-clicked on and cleared. This unlocks all the related fields and makes the form free for editing.
Is there a way to lock the digital signature to prevent using the “Clear Signature” function?
Thanks for any help,
Richard

George,
Thanks for the quick reply. Upgrading to Acrobat 9 may be an option. If not, is there a way to lock these fields with scripting? Or applying a password after signing?
Thanks again,
Richard

Implementation of digital signature

Hi,
Need to implement digital signature.Scenerio is such that if any user access t-code pop should come and it ask for user and password and it also ask while saving any data.
Any suggestion will be appreciated.
Regards

Not a good idea for user to enter password everytime they execute the report or do changes to a document. Mean user will spent 60% time to just typing the passwords.
Why you need this? As you have initial SAPlogon userID/password?

Digital signatures for use in consenting research participants

Hi. I need some help implementing digital signatures into a consent document. I work as a research assistant at a university and in our line of research, we have participants from multiple regions of the country. One of the most important parts of staying in compliance with various regulations is that all research participants are presented with information about the study, and they must sign a document to indicate that they understand the risks/benefits involved.
We want to implement digital signatures to make this process easier for ourselves and the research participants who live across the country. However, there seem to be some technical hurdles in using signatures. First, we want to make sure that participants who only have Adobe Reader are also able to sign (my understanding is that they should be able to). Some participants may not be very computer savvy, so we need the process to be somewhat dummy-proof. Participants must fill in their printed name and date, so I need for them to have authority to change some information, but I don't want them to have the authority to change the document itself or the participant ID numbers which I have to fill in once I get the form back.
I have created a fillable form in Adobe LiveCycle and added 2 signature form fields, one for the participant, and one for myself. I plan on distributing the form so that I can have a dataset file for all of the returned consents.
Essentially the process should work like this:
I send a participant the form, they fill out the fields for their printed name, date, and provide their digital signature and use the submit by email button to return the form to me.
I receive the form, add their participant ID number, and provide my digital signature.
Save the file in our dataset file which is associated with the returned consent forms.
The thing I'm concerned about is their digital signature being invalidated once I insert the ID numbers and add my own digital signature.
Thanks for any help you could provide.

We have a document that needs to be signed by more than one individual -- and in our process we are using the Topacz signature pad to get the signature. It's similar to the one you sign at the grocery store, drug store, etc. In order to NOT have the first signature invalidated, we were told to edit the registry...and it works perfectly!
[HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\8.0\AVAlert\cCheckbox]
"iDigSigSaveAsCertified"=dword:00000001
[HKEY_CURRENT_USER\Software\Adobe\Adobe Acrobat\8.0\AVAlert\cCheckbox\cAnnots]
"iReaderEnableSaveWarn"=dword:00000001
Obviously if you are using a different version of Acrobat, you'll have to change the key accordingly.
Hopefully this will work with your process.
Good luck!!
