PDF data encryption

Hello
I have a PDF form which will be available over a public website for users to download and fill their information. Upon filling and clicking the Submit, the PDF will invoke my servlet which is deployed on Websphere Server. Is the data transmission from users desktop to the Servlet Encrypted? If so, what level of encryption that adobe provide? If not, how do we encrypt this data transmission for PDF to the Servlet? Appreciate your response.
I have the following setting for the Submit button:
Submit as URL encoded HTTP POST, UTF 8.

The https is using an ssl connection and yes it is encrypted (while it is being transfered).

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?

Is it possible to perform network data encryption between Oracle 11g databases without the advance security option?
We are not licensed for the Oracle Advanced Security Option and I have been tasked to use Oracle Network Data Encryption in order to encryption network traffic between Oracle instances that reside on remote servers. From what I have read and my prior understanding this is not possible without ASO. Can someone confirm or disprove my research, thanks.

Hi, Srini Chavali-Oracle
As for http://www.oracle.com/technetwork/database/options/advanced-security/advanced-security-ds-12c-1898873.pdf?ssSourceSiteId… ASO is mentioned as TDE and Redacting Sensitive Data to Display. Network encryption is excluded.
As for Network Encryption - Oracle FAQ (of course this is not Oracle official) "Since June 2013, Net Encryption is now licensed with Oracle Enterprise Edition and doesn't require Oracle Advanced Security Option." Could you clarify this? Thanks.

How read pdf data in C#?

Hi,
Is there any way to read pdf data in C#. The application i am working on demands to preserve the layout, formatting from the source and just change the content if required. Is there any open source or commercial API which i can use.
Thanks,
Mehul

The Acrobat SDK is designed to allow developers to do two things:
Write plugins for Adobe Acrobat and Adobe Reader using C++
Control Acrobat from external applications (via IAC)
It will not do anything without Acrobat and/or Reader installed, so as a standalone way to read or modify PDF files it's of no use.
The Adobe PDF LIbrary is a standalone set of tools to work with PDF files (so Acrobat is not required) and it can be operated from a server, unlike Acrobat.
If you have questions relating to the SDKs, please posts them in the Acrobat SDK forum rather than here.
Having said that, the PDF file format is an open standard based on COS objects - depending on what precisely you are trying to do, it may be just as easy to parse the files yourself. Rendering PDFs to screen is a very complex task but creating/editing them isn't - things only tend to become difficult when you involve encryption.

Listener Start Problem with TDE (Transparent Data Encryption)

i am testing Transparent Data Encryption in Oracle 10g by using the following link
http://oracle-base.com/articles/10g/TransparentDataEncryption_10gR2.php
Before Implementing the TDE listener was running fine but after implementation of TDE the listener was unable to start
Please check the steps which i follow
Step1-
specify the ENCRYPTION_WALLET_LOCATION parameter in the sqlnet.ora file, now SQLNET.ora file looks like the following
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
ENCRYPTION_WALLET_LOCATION=
(SOURCE=(METHOD=FILE)(METHOD_DATA=
(DIRECTORY=D:\oracle\product\10.2.0\wallet\)))
please check the contents of listener.ora file,i didn't make any configuration changes for listener before or after implementation of TDE
SID_LIST_LISTENER =
(SID_LIST =
(SID_DESC =
(SID_NAME = PLSExtProc)
(ORACLE_HOME = D:\oracle\product\10.2.0\db_1)
(PROGRAM = extproc)
LISTENER =
(DESCRIPTION_LIST =
(DESCRIPTION =
(ADDRESS = (PROTOCOL = IPC)(KEY = EXTPROC1))
(ADDRESS = (PROTOCOL = TCP)(HOST = shakeel-pc.lhr.inov8.com.pk)(PORT = 1521))
Step2-
CONN sys/password AS SYSDBA
ALTER SYSTEM SET ENCRYPTION KEY AUTHENTICATED BY "myPassword";
TDE implemented successfuly implemented.
But when i try to stop/start listener

TNS-12560: TNS:protocol adapter error
TNS-00583: Valid node checking: unable to parse configuration parameters
Listener failed to start. See the error message(s) above...
To start the listener i have to close wallet as
1- SQL>conn sys as sysdba
ALTER SYSTEM SET WALLET CLOSE;
2- Replace the SQLNET.ora file as previous ,now SQLNET.ora contains
SQLNET.AUTHENTICATION_SERVICES= (NTS)
NAMES.DIRECTORY_PATH= (TNSNAMES, EZCONNECT)
Now if i start the listener then the listener was started succesfuly
Please suggest why listener is not being start with TDE?

I have the same problem. I'm testing TDE using Oracle 11gR1. After setting the parameter encryption_wallet_location and restart the listener, the listener failed to start. The error is exactly the same
TNS-12560: TNS:protocol adapter error
TNS-00583: Valid node checking: unable to parse configuration parameters
By removing the parameter encryption_wallet_location, the listner can be started successfully.
Anyone can help?

Need suggestion for data encryption

Hello Experts,
I need your expert opinion on one of the data encryption method. We have some legal compliance to implement data encryption as listed below, lets say we have to apply encryption on 2 tables (1) TAB_A (2) TAB_B.
(1) Need data encryption on the TAB_A & TAB_B for 2-3 columns and not the entire table.
(2) Data should not be in readable format, if anyone connect to database and query the table.
(3) We have reporting services on our tables but reporting services doesn't connect to our schema directly rather they connect to a different schema to which we have given the table Select grant.
(4) Reports should work as it is, and users should see the data in readable format only.
(5) There are batch processes which generates the data into these tables and we are not allowed to make any changes to these batch processes.
This is a business need which has to be delivered. I explored various options such as VPDs, Data encryption methods etc but honestly none of these are serving our business need. There is also a limitation of encrypting data as data volume of quiet high (30TB DB) and generally users query the data on millions of records at a time. Also reports have very tight SLAs as well. If we create any encryption wrapper then decrypt will take longer in reports and will cause the SLA miss for reports.
Could someone please suggest any better solution to me or if something is inbuilt in Oracle? We are using Oracle 11g.
Regds,
Amit.

Encrypting a password is itself not secure. Anything that can be encrypted can be decrypted. That is why Oracle itself DOES NOT encrypt passwords.
Surprised??
Here's what Oracle does with passwords, and what others should be doing if they have to store them.
When the password is created, the presented password - clear text - is concatenated with the username. The resulting character string is then passed through a one-way hashing function. It is that hashed value that is stored. Then when a user presents his credentials to log on to the system, the presented credentials are combined and hashed in the same manner as when the password was created, and the resulting hash value compared to the stored value.

Solution for Prefilling PDF data

I called and spoke to a sales associate asking about LiveCycle for use to prefill pdf data for one of our large customers. He told me the cost was very high for LiveCycle and to come and ask here on what to user. I am familiar with now unsupported pdf-fdf solution but I am wondering if there is another solution that I'm unaware of. Any help would be greatly appreciated.
Thanks.

Yeah, I have looked at the FDF toolkit, and we've used it before, but I'm wondering if there are other solutions available. My company is a commercial printer so we are familiar with vdp programming, but I'm not very up to date on what the successor to the FDF Toolkit is. Primarily I required something with a tighter and more secure integration than FDF allows.
Client produces many enrollment forms that we prepulate dynamically using VIPP (http://en.wikipedia.org/wiki/Variable_Data_Intelligent_Postscript_Printware) when we recieve the print requests. They pay us for the programming to do this and it gets pretty high as we have to manually get the coordinates of each field, in each page of the print file that we need to populate and then program them into our templates using VIPP. They make edits to their forms every quarter and each form that has a change that moves as much as a line feed has to be completely recoded in VIPP. We want to reach a solution where they can have pdf, or web form of some sort on our end and submit the data to us to populate and print high res. Lower cost all around but consistent, professional output.
Thanks in advance.

Thanks friends,
I have also added some javascript in PDF.
I pass some parameters throgh url to PDF and then display this parameters in PDF fields .
Javascript is as follows :
var
sURL = event.target.URL;
var
nRequestStart = sURL.indexOf("?");
if
(nRequestStart > 0) {
var sRequest = sURL.substr(nRequestStart + 1);this.rawValue
= sRequest;
var aRequests = new Array();aRequests
= sRequest.split("?"); this.rawValue
=decodeURI(decodeURIComponent(aRequests[0].substr(7)));}
This code work well in adobe reader and acrobat also (some user use acobat).
but now when I user this HTTP button , form works well in abode reader
but show soem alert message in acrobat 7.0 pro such as
