Signed classes & preventing code modification
Hi, I've got a generic question concerning preventing code modification.
Suppose I have written some neat code (yeah, that might happen, one never knows ;-)) and I want to bundle it in a JAR AND make sure nobody will modify my code (at least, without a warning).
All right. I make up my JAR, and I sign it. This adds a SIGNER.SF & SIGNER.DSA/.RSA to the JAR.
Yes... but... what prevents another person from:
1. downloading my JAR
2. unjarring my JAR, and retrieving the important .classes
3. eventually, modifying the .class (to make my code silly and ugly for instance ! ;-( ).
4. make again the JAR, and sign it with his own keys
You'll tell me: "Yes, this is possible, but then the code is signed by him, not by you !". Correct... But who will warn the user that has downloaded my code that he's not using "my" code but another one.
I'll have to tell him "check the signature is 0215AB45...". 1/ This is Highly unpractical... 2/ If He's the bad guy, this does not prevent him from modifying my code !
Any solution or interesting thoughts for that topic ?
Thanks,
Axelle.
Signing is not intended to prevent modification, java classes can always be decompiled, modified and redistributed. What signing does is allow modification to be detected.
If a user has your public key, he will be able to detect that the (modified) jar was not signed by you, and hence is untrustworthy.
Similarly a java application can detect that a given jar file (or even object, eg: an authentication token) was not signed by you, and hence cannot be trusted. If however the Bad Girl has access to the application code, she can decompile said application code and modify it so that it doesn't care.
If you want to protect your code, you can try obfuscating it (there are various obfuscation tools around, do a search on google), but all this does is make the decompiled code less easy to read (variable names all a1, a2, etc), and won't really stop anyone who is serious about stealing your cool code.
Another option might be to deploy a compiled version (if you are distributing an application to a single platform), but this won't work with applets, loses the portability of java classes, and if the Bad Girl is good enough (and determined enough) it will only slow her down (though probably a fair bit).
The only sure fire way I know of preventing your Java code from being stolen is to not distribute it, which is hardly useful.

How Midlet Signing prevents code modification.
Hello
I've previously read somethings about signing but never experienced it.
I have a question now.
Every where it is said that signing a midlet prevents others from modifying my code and distribute it under my name.
Is this easy for any user to check the certificate owner on his handset??
And could you please tell me how it can be done??Yeah, I'm pretty sure of that thanks to watching the diagnostics window. Everything falls apart at that point. Yes, Class 3 root certs are installed on the devices.
We're regenerating our cert, so we'll see what happens then and hopefully our problem is solved.
Thanks for the reply! -

Explicit Enhancement Options
There are two types of explicit enhancement options: Source code enhancements with source code plug-ins and BAdIs:
Explicit enhancement options of the source code enhancement type allow you to insert source code plug-ins. These are lines of code that are executed if the source code enhancement option is inserted in the code with the Enhancement Point command. Source code enhancement options with the Enhancement Section command behave the same, except that the source code plug-in replaces the section in the original code. Therefore, you are not only able to enhance the original code, but can also flag specific code sections (as enhancement sections) so that other developers can replace these sections with other code without making modifications.
Business Add-Ins (BAdIs) are hangers for object plug-ins. A BAdI definition comprises an interface with methods. BAdIs are enhanced by classes that implement the BAdI interface. If you instantiate a BAdI and then call its methods, you can, among other things, specify which method implementations are to be carried out on the basis of filter values. In other words, a BAdI method call is a dynamic method call with a specified interface, for which it is not determined until runtime which method implementations are to take place.
In the case of source code enhancements, the definition and call coincide. You define BAdIs once in the BAdI Builder and can then call them at different points in the various compilation units.
Implicit Enhancement Options
Implicit enhancement options are fixed points in compilation units that is, points that remain intact even if the code is changed. This is important for the following reason: If the location of an enhancement is moved, you have to check manually after an upgrade whether the enhancement is still at the correct point and replace it if necessary. The following are implicit enhancement options at which enhancements can always be inserted:
You can always insert source code plug-ins before the first and the after the last line of includes, methods, reports, and function modules.
You can always add further optional parameters to function modules.
For global classes, there are different permanent, implicit options for enhancements: You can insert additional attributes or methods, and you can add optional parameters to existing methods
Customer-Specific Modification and Enhancement Possibilities
Use
The following documentation provides an overview of the customer-specific modification and enhancement possibilities in the IS-H System. Note that to implement enhancements, you require ABAP programming knowledge.
Features
The IS-H system provides the following technical possibilities for customer-specific modifications and enhancements
Business Add-Ins (BAdIs)
If default code (standard procedure defined by SAP) exists for the BAdI, please note it will be overwritten when you implement the BAdI. You can, if required, re-use the default code in your implementation.
As of SAP NetWeaver 2004, the enhancement concept of the ABAP Workbench (Enhancement Framework) is available for BAdIs. Note that SAP Patient Management contains BAdIs that use the Enhancement Framework as well as the classic BAdIs.
Customer Exits (transaction SMOD)
If SAP delivers sample code for the customer exit, you can access it when implementing the exit by choosing Goto ® Sample Code. You can re-use the sample code using Copy&Paste
User Exits from the IS-H Implementation Guide: Basic Settings ® Configuration/Systems/Events ® Display SAP User Exits.
To implement the IS-H user exits, copy the function module delivered by SAP into a customer-specific function group. The name of the function module delivered by SAP is specified in the table you call in the IS-H Implementation Guide by choosing the path specified to the left here.
Once youve copied the source code, you can modify this copy to meet your needs. Note that you must not modify the interface of your own function module.
Now enter the name youve chosen for the function module in the customer table. You access this table by choosing Basic Settings ® Configuration/Systems/Events ® Configure Customer User Exits.
If it is helpful rewards points.

CGLIB generation from signed classes(in signed jar) = SecurityException
Good Day!
I have the following problem:
My project uses a number of JARs signed with a jarsigner tool from JAVA distribution package including hibernate2.jar (the jar with all the hibernate stuff), spring.jar and cglib.jar (I think, exact names doesn't matter). All this jars are signed off course for security reasons.
Then, I have my project working with Hibernate, and it uses lazy-initialized ORM-classes, so Hibernate tries to generate a proxy via CGLIB for these classes. But during initialization of Hibernate SessionFactoryImpl I'm getting a java.lang.SecurityException:
java.lang.SecurityException: class "cern.spsea.hibernatebeans.BeamFileHibernateBean$$EnhancerByCGLIB$$773cc7e9"'s signer information does not match signer information of other classes in the same package
cern.spsea.hibernatebeans.BeamFileHibernateBean is one of my ORM-classes and all my classes are not signed because they are in development (they are not in jar, so they can not be signed).
I think it happens because signed code (from hibernate.jar and cglib.jar) tries to generate another signed code (cern.spsea.hibernatebeans.BeamFileHibernateBean$$EnhancerByCGLIB$$773cc7e9) but relate it to my unsigned package (cern.spsea.hibernatebeans).
So, I have a couple of questions:
1. Does signed code generates also signed code?
2. If so, what can I do for development? I really need to avoid this problem only at development, because at release my classes will be also in the signed jars. Can I force CGLIB to generate not signed classes? Is it some options in JVM start command to skip security checking? May be something else?
Any help is appreciated!
Thanks a lot in advance!
RomanI've got the same problem, if someone could help us he'll be very helpful.

Problem in SAP standard code modification for FB03
Hi Experts,
I am adding 4custom fields in FB03 tcode by doing a SAP standard code modification in SE51.
The program name is SAPMF05L and screen no. is 302(In some SAP verion, it is 304). This is the screen for document line item of an invoice.
My problem is:
When I add the fields in the screen, in which module will I put logic in the PBO and PAI as I am unable to figure out the German comments and the program structuring.
Also, if anybody can tell me what to write as I am little bit confused about the logic of populating my fields with the values.
FB03 is a display transaction so I have to keep my custom screen fields disabled.
Regards,
Sangeeta.Hi Sangeeta,
For enhancing the screen of this Tcode, first of all search is there any Screen enhancement is provided by SAP or not and in case if it is provided then use that only.

Hi Experts,
In ADRC table entry for an addr number, there is # sign in postal code field (NG26BJ#).
And due to this incorrect # sign, there are issues occuring in the system.
Can you suggest where do I search for this # sign in the system?
I mean I searched for customer master, vendor master, etc but could not find out # sign in any partner data postal code field.
Please suggest.
-Chetan.Check all the tables that are on 'where used' list for ADRNR data element in dictionary (SE11).
If it is an "orphaned" record, BW interface should not be actually pulling it in. I would recommend to base the interface on the main table (e.g. KNA1) and only pull ADRC records that are referenced.
The easiest solution would be to write an ABAP report to update the record directly in the database. I wouldn't delete it though, just removed the # sign. Also check the OSS notes or send a message to SAP and they might provide such report for you. -
Sign the Applet code using pfx certificate got Error?
I use my existing certificate (.pfx) to sign my applet code as follows (without any key gen. before, directly sign by this certificate)
jarsigner -storetype pkcs12 -keystore C:\mycert.pfx AppletCode.jar keyEntries
Although the code can be signed, when i view this page, it prompts me "Certificate not verified" and with error:
java.security.cert.CertificateException: Check leaf key usage failed in certificate.
What is wrong? Any body can help me?
* I try to geneate the self-certificate by keytool to sign my code, it can be viewed properly.1) Check if your .pfx certificate has the following purposes (read it using the venerable Internet Explorer):
Ensures software came from software publisher
Protects software from alteration after publication
2) Put your certificate in the cacerts file -
I can't Enter User Fields in Asset Class (t.code S_ALR_87009007)
Hi All,
In customizing I've to "Enter Your User Fields in Asset Class" (t.code S_ALR_87009007).
SAP doesn't allow me to change the filling in the view, I only can display them.
What cuold it depend on.
Thanks for your help.
G.Hi Rossi,
This is not an authorisation issue at all.
S_ALR_87009007, this tcode can be used to maintain a default Eval Group for asset master creation with the specified asset class.
If your Maintainace Level at CLASS is not maintained for any evaluation group, you can edit the values over thers.
SPRO-> FA-> AA ->Master Data -> Screen Layout -> Define Screen Layout for Asset Master Data -> Define Screen Layout for Asset Master Data....here select your screen layout, which is assigned to your questioned asset class on OAOA and click on logical field groups -> Allocations -> Field Group rules.
Here for all eval groups, make the field status to optional and select check boxes CLASS, MNNO, SBNO and SAVE.
Now check with S_ALR_87009007, here you will be able to edit the inputs.
Hope this will resolve your issue.

VeriSign Java Object Signing (Class 3) Digital ID
Hi,
I have a VeriSign Java Object Signing (Class 3) Digital ID.
How do i convert this to a file i can use for signing?
I previously had a '.p12' file and used jarsigner which worked.
Any help would be greatly appreciated!
Thanks,
JI just received our Verisign "Java Object Signing
(Class 3) Digital ID". When I try to import it I get
the following error:
keytool error: java.lang.Exception: Input not an X.509
certificate.
The command I am using to import the cert is :
keytool -import -alias pcs -file cert.cer -keystore
vs.keystore -trustcacerts
Any idea what I am doing wrong? I am using JDK 1.3,
do I need to upgrade to 1.4 to import certs currently
being provided by Verisign?
Thanks,
JimIf you did as I did and ordered a rsa certificate, you need to add the option
-keyalg rsa
to your command line.

I have Question or rather Suggestion for Apple about IOS devices.
If apple could introduce one more security Step to prevent signing out from iCloud or disabling the location finder, it could be great help to recover lost device. the Reason IF one have Free account and some times iOS device is used by kids who actually know the login and password but there could be sort of PIN code or admin password which should have been required if the used want to sigh out of iCloud or disable the location services, and if that PIN is not provided it should prevent disabling the location service and iCloud sign out, similarly when erasing iOS device after asking the login and password before proceeding for complete phone erase it should ask for PIN authentication which is set separately like passcode of device.Hi Paul,
In order to sign out of your Apple ID on your iPad, follow the steps in this article -
iTunes Store settings - iPhone
If you are using iCloud, you will also want to go into Settings > iCloud > select Sign Out, the last item on the page.
Thanks for using Apple Support Communities.
Best,

Step by Step Instructions for Installing Self Signed Certificate using Certificate Modification Tool
I am looking for some step by step instructions for installing the self signed certificate from my Microsoft SBS 2003 server on a Treo 755p and 750p. In particular I need some help with the form of the actual certificate and how to use the Certificate Modification tool.
Some questions I have are as follows:
1. When I install the certificate on a Windows Mobile device I used an exported version of the certificate. This export is done using the DER x.509 format. Is that the same form I’ll need for the Palm? Do I need some other form? Can/should I just use sbscert.cer file that is generated when SBS is configured?
2. Does the self signed cert need to be installed on the computer being used to update the Palm or do we just need to be able to access the appropriate .CER file?
3. There are three things included in the PalmCertificatesTool.zip file:
Trusted CAs (folder)
Cert2pdb.exe
PalmCertificates.exe
How do I use these tools?
4. It looks like the PalmCertificates.exe file opens an interface that will allow me to browse to the desired .CER file. Then I suppose I use the < Generate PDB > to create something that needs to then be uploaded to the Palm device? Not having any real experience with a Palm device how do I upload and install this file?
5. Once uploaded do I do something on the device to install it?
If there is some white paper that provides step by step instructions on doing this that would be great.
Thanks,
Walt Bell

Post relates to: Treo 755p (Verizon)Thanks for that.
I have one question after reading the article 43375:
The article has you "Turn of AutoSync" and then "Reset the device". It then indicates the device should be left idle.
The next step relates to running the PalmCertificates.exe, navigate to the certificate file and add it and then run the < Generate PDB > button. Should the device be connected to the computer during this process? If so, at what point after the reset do you connect it to the computer?
Thanks!

ABAP Code Modification for Command Tickets
Hi Experts
Modification to processing of Command Orders & Tickets
We require a modification to the processing being performed on sales data originating from the Command Concrete system and potentially from other systems yet to come online (e.g. Reddies Cement plant).
The Sap process involved is
ZINT_INBOUND_POLLING and within that,
ZINT_CSTPORD_ROUTINES.
The problem
Currently there is an assumption that every sales order (and its deliveries) will include a product which is made to order, i.e. for which a production order will be required.
In ZINT_CSTPORD_ROUTINES, a check is made to identify the production order linked to the sales order. If there is no such production order (usually because of the customeru2019s credit status) then processing of the ticket is terminated.
This assumption would fall down if an order was to be raised (in Command) on which there is no concrete material. For example, if we sold a bag of pigment or a screed to a customer. In this case the item would be sold from stock and there would be no need for a production order
The solution
In the routine which checks for the existence of a production order, modify the code as follows:
Inspect each item on the sales order
If (and only if) there is at least one item with a category of u201CZTACu201D then check for a production order, otherwise process the order in the usual manner.
The following Coding of programs are below.
Report: ZINT_INBOUND_POLLING
Description: REDDIES Interfaces: Polling Job for Inbound Interfaces
This report is a general file polling and distribution job for
inbound interfaces. Interfaces are identified by their assigned ID
and type values (refer to table ZINT_ADMIN). The polling job can be
run only for a single interface. This restriction has been implemented
for performance reasons. Dependent interfaces should be set up as
separate, dependent jobs in SM37.
For an interface to be triggered by this report, it must have:
1. Administrative parameters entered in table ZINT_ADMIN.
2. Other parameters (eg. organisational data such as plant or store)
entered in table ZINT_PARAM.
3. An interface-specific function module created in accordance with
the inbound interface template (ZINT_INBOUND_INTERFACE).
4. An interface-specific directory structure. This structure must
be reflected in the directory parameters of table ZINT_ADMIN.
Note that the directory names supplied in ZINT_ADMIN must exactly
match those used for the actual directories.
This job is designed to run as a periodic background job, but can
also be run on-line when required.
On each execution, the program performs the following tasks:
1. Validate all selection parameters.
2. Read interface administration and other parameters.
3. Check the inbound directory to see if there are any new files.
4. If there is a new file.
4.1 Read the data and update the interface log.
4.2 Archive the data and update the interface log.
4.3 Call the interface function module, sending data and parameters.
4.4 Log any messages returned from the function module.
5. Exit.
Please document all changes to this job carefully and clearly. Major
additions to functionality should be put in new, parameterised form
routines wherever possible to sustain maintainablility of the code.

Hi Experts
I found in SAP code the usage of * sign but it wasnt in select statement. Anyone knows how below statement works?
i_frggr = *ekko-frggr
Thanks in advance.
azHi,
the statement with *
i_frggr = *ekko-frggr
you can find in the declarations that they would be declared in this way
Tables : *ekko,
ekko.
These kind of declarations are used in the programs which has updates in it...
so *ekko keeps the older value and it is treated as a normal work area only, It has no special meaning attached to it.
ekko holds the modified or updated value which has to be updated in the database table.
so to differentiate between older values and modified values
they used '*' to differentiate them thats all,
Regards,
Siddarth
