Encrypting an XML file data

Hi All
I am new to Java security. I am stuck where i need to write the handler for the webservice.
I need to encrypt/sign the XML data using the some certificate.
I am having the certificate (pfx) and JKS file with me which i got from the web service producer.
Could some one let me know how can i encrypt this XML with above certificate.
Please let me know if you need some more information.
Thanks

If you are serious about doing this work then you should learn a good bit more about cryptography. A good starting point is

Error while encrypting the xml file using asymmetric cipher...pls help

i am encryption the xml file using asymmetric cyper....
in one class , i am generating private key and public key using "RSA" algorithm..using 1024 byte initialization...
it is generating properly...
and after that in second class i am encrypting the xml file using "DESede" algorithm and i am using public key of above class..
but i am getting exceptione :

is there any site for where source code of xml file encryption using asymmetric cipher is available?
pls, help me.....

Sachin,
What sabre150 is trying to explain to you, is that encrypting data (such as an XML file) is a 2-step process. In the first step, you generate a symmetric key (such as DES, 3DES, AES) and encrypt your file with this key (and the appropriate mode and padding).
In order to ensure that your encrypted data cannot be decrypted by unauthorized individuals, you now need to protect the symmetric key. Encrypting your symmetric key with another symmetric key does not solve the problem, since you have a chain of symmetric keys that need to be encrypted into infinity.
Cryptographers solve this problem by encrypting the symmetric key with an asymmetric key, such as as RSA. To perform this second step, you generate an RSA key-pair, encrypt the symmetric key you generated in step 1 with the Public key of the RSA key-pair, and give the recipient of the encrypted XML file, access to the Private key of the RSA key-pair as well as the encrypted symmetric key.
The recipient, then uses the RSA Private key to decrypt the symmetric key first, and then uses the "plaintext" symmetric key to decrypt the XML file.
What sabre150 was also attempting to explain to you, is the traditional way of transporting an encrypted "blob" that consists of data + symmetric key. With a modern key-management system, combining the two would be unnecessary.

Converting text String to XML file data

need some guidance. I have to create a XML file of a huge Text File.
I am parsing the text file according to relevance and passing a set of data each element and attribute seperated by "_".
I need to create to Xml file out this. It has to be current process as I need to keep on adding new elements and attributes.
e.g.
Passing this string
String temp("Name_Age_Birthdate_Birthplace_Place_teleNumber");
Need to add this to XML of format
<Directory>
<Person>
<Name>
<Age>
<Birthdate>.....
</Person>
<Person>
</Person>
</Directory>
The problem not all attributes may be present at some time..
e.g.
the person's age may be absent some times.. during that time the xml file should look like <Age/>
I will need to keep on updating Person list concurrently after the file has been created..
Need Urgent guidance.. I am still New to java
A guidance code or link is awaited..
Thanks.. a Lot

Do you need to stick to the XML support that comes with Java 1.4 or can you use Third-Party stuff? I'm asking, 'cause I think JDOM is much easier to use for a newbie than the build-in XML API ... and it comes with a VERY easy to use class XMLOutputter that creates XML files!
Take a look at JDOM:

Encrypt & Decrypt XML files

Hi All,
I am new to the cryptography. I have one application which will transfer XML files from the machines which uses Windows/Java platform to the machines which uses Linux/C and also vice versa.
I want to encrypt the files before transfer and decrypt the files after transfer on both the sides. Is there a common technology for handling this? Any info? Thanks in adv.
-Bh_t_76

So, I thought of getting ideas from the people who
have already done similar work. I think the forums
are meant for that. The topic is too broad. The forums are normally for specific problems and your request requires at least one book as an answer.
If you know nothing about encryption then you need to find and read books on the subject. Not just Java books, but general encryption books. There are plenty out there of various standards.
One of the books in my library is http://www.schneier.com/book-applied.html but you may want to start with something a little less weighty. Visit http://www.crypteon.co.uk/cryptography-books.htm to get some ideas.
Once you have a basic understanding of modern cryptography then study the JCE tutorial and come back with specific questions.

Loading XML file data

Hello
I am using Spry.Widget.AutoSuggest to sort the data from an
external XML file
In the XML there are some url-s pointing to pictures to be
loaded but the problem is that they all loads in the cache as the
page initializes.
Although they are not shown at the begining i can see them
caching ( firebug for mozilla)
Is there any way to load the appropriate pictures (data) just
after it matches the AutoSuggest search criteria.
the example files are :
http://www.evtinobg.com/newWebSite/_search.php
http://www.evtinobg.com/newWebSite/models.xml
thanx a lot

Please read the FAQ thread and posting guidelines... Also please see the XML DB basic demo.. And try forum search, this question (or variant's of it) have been asked and answered so many times that it's really not worth starting (another) new thread on this issue.

Most efficient way to load XML file data into tables

I have a complex XML file running into MBs. I want to load it's data into 7-8 tables.
Which way will be better:
1) Use SQL Loader to actually load directly into the 7-8 tables directly by modifying the control card.
Is this really possible and feasible? I am not even sure about it
2) Load data as XML Type in a table and register it. Then extract from there to load into various tables.
Please help. I have to find the most efficient way of doing it.
Regards,
Sudhir

Yes it is possible to use SQL*Loader to parse and load XML, but that is not what it was designed for and so is not recommended. You also don't need to register a schema, just to load/store/parse XML in the DB either.
So where does that leave you?
Some options
{thread:id=410714} (see page 2)
{thread:id=1090681}
{thread:id=1070213}
Those talk some about storage options and reading in XML from disk and parsing XML. They should also give you options to consider. Without knowing more about your requirements for the effort, it is difficult to give specific advice. Maybe your 7-8 tables don't exist and so using Object Relational Storage for the XML would be the best solution as you can query/update tables that Oracle creates based off the schema associated to the XML. Maybe an External Table definition works better for reading the XML into the system because this process will happen just once. Maybe using WebDAV makes more sense for loading XML to be parsed (I don't have much experience with this, just know it is possible from what I've read on the forums). Also, your version makes a difference as you have different options available depending upon the version of Oracle.
Hope all that helps as a starter.

Upload XML file data into internal table

Hi,
I need help from you.
I am uploading XML file from Application server.
1.In application server under directory it may have several XML files and i need to upload all the XML files when we gave only directory name. So, what is the function module for that logic . If possible code also.
2.Once we get the files into some internal table we need to upload data from that files to internal table.
So what is the logic for that , if possible code also.
I am giving sample directory:
For example in this directory assume 3 xml files are there.
I need to upload those files and data from that in to internal table.

How to load xml file data

hi ,
I know how to load data from csv file...
Anyone can guide me for how to load data from xml file
i need step by step guidence
from
naman

hi naman shah,
you can used XML DOM in SAP in order to read data from xml file
first step to do that, you need to read the xml file using OPEN DATASET
after that you convert the content of the file to XML DOM class in SAP using function modul SDIXML_XML_TO_DOM
after that you can read / manipulate the data from xml.
for the XML DOM class documentation in SAP, please refer to http://help.sap.com/saphelp_crm50/helpdata/en/bb/576637dca511d4990b00508b6b8b11/frameset.htm
hopes it helps

XML file data

Hello
The attached xml file contains data that I would like to extract. The data value has the tag (ubchild???/)name of "mean'. This can occur quite a number of times within the file for different child names. e.g.
<Key>SENS0710:10951:IntSolIrr</Key> has the value as
<Mean>742.320755</Mean>
and
<Key>SMBAU008:154000347:m_S0 kWh</Key> has the value as
<Mean>227.458679</Mean>
and so on....
The attached vi is very very simple and uses the JKI EasyXML vi to parse the file to a labview data type.
This is the point at which I need some guidance as to move forward. I have looked at using variant to data, clusters etc, but can't seem to get anything near working.
Would somebody be so kind as to give me some advice or tips as to extract these values to an array.
Thankl you

How to search xml file data based on the given keyword from html form

hi,
i'm new to XML. I have this problem regarding searching within a XML file.
the
idea is that my search will be based on the keyword entered
in
by the user from a HTML form. the keyword is then used to search all
the
question nodes and the choice nodes within a XML file. once the match
is
found, i will have to display the results.
But i don't know how to do so - especially the part of searching xml file.
Can
anyone help me in this? Your help is much appreciated.
Edited by: Moti_Lal.D on Apr 4, 2008 7:28 AM

yeah.. what i was trying to do is
i have one xml fine. then i have to read all the tag values say
<book>
<title>Java</title>
<author>agarwal</author>
<price>200</price>
</book>
<book>
<title>Xml</title>
<author>saxmann</author>
<price>300</price>
</book>
i can read the tag values like this
File file = new File("dom.xml");
try {
DocumentBuilder builder = DocumentBuilderFactory.newInstance().newDocumentBuilder();
Document doc = builder.parse(file);
NodeList nodes = doc.getElementsByTagName"book");
for (int i = 0; i < nodes.getLength(); i++) {
Element element = (Element) nodes.item(i);
NodeList title = element.getElementsByTagName("title");
Element line = (Element) title.item(0);
what i want is i may give any xml file
like File file = new File("xxx.xml");
(it may be one level/two level/3level tagged one)
then the i should read all the tag values and store them in some array. Then when i enter some character from keyboard (say "a") then it has to show all the tag values starts with "a" and display them.
i guess u understand my problem.
