PDF password protected [message #248495]

Hi,

I have the following question: is there any possibility to assign a
password to a report such as if the user wants to modify the generated PDF
in Acrobat Reader, not to be allowed (only if they know that password)?

Thank you,
Cristian

Hi. I posted this message a couple of days ago but no answer. Does anybody
have any idea is it is implemented or not and if yes how to use it? The
problem is: password protected PDFs: we would like to generate PDFs that
cannot be modified by user (only if they know a password or something). We
are generating reports that are sent via email to user, and we would like
to make them password protected or read only (the user is not allowed to
modify them in Acrobat program).

Thank you,
Cristian

I didn't find anything anywhere about PDF protection in BIRT. My solution
would be to use iText tools to protect the generated report with a
password or smth.

I agree, use iText.

example code, encrypting with an ownerpassword:

final PdfReader reader = new PdfReader(fileName);
final File destinationFile = File.createTempFile("report_encrypted_",
".pdf");

PdfEncryptor.encrypt(reader,
new FileOutputStream(destinationFile),
null,
password.getBytes(),
PdfWriter.AllowPrinting,
false);

final File sourceFile = new File(fileName);
sourceFile.delete();
destinationFile.renameTo(sourceFile);

But wouldn't it make sense to log a bug against Birt to allow this out
of the box, by setting some configuration variable?

Hi, I'll continue this thread with another issue.

I was trying to implement the following scenario:
From the app, I'll invoke the BIRT ViewerServlet and catch whatever it
generates in a byte array. This byte array is then casted to a PdfReader
object and the rest you well know (apply the password with iText tools
aso). I would prefer not to save the generated PDF on a local disk and
then to open it.

Now the issue is that when I open the new connection to the BIRT
ViewerServlet, I'm loosing the previous session. I've tried to set also
the cookies but no success. I'm curious if anybody had this issue before
and how did they solve it.

Thanks,
Cristian

/*===code sample===*/

ServletOutputStream out = null;
String param1 = "test1";
String vPath =
" http://localhost:8080/myApp/secure/run?__format=pdf&__lo cale=EN&__report=myDemoReport.rptdesign&param1="+param1+"&timestamp="+(new
Date()).getTime();
HttpClient client = new HttpClient();
GetMethod method = new GetMethod(vPath);
DefaultMethodRetryHandler retryhandler = new DefaultMethodRetryHandler();
retryhandler.setRequestSentRetryEnabled(false);
retryhandler.setRetryCount(3);
method.setMethodRetryHandler(retryhandler);
Cookie[] cookies = client.getState().getCookies();
Cookie cook = new Cookie();
cook.setName("foo");
cook.setValue("bar");
client.getState().addCookie(cook);
try {
// Execute the method.
int statusCode = client.executeMethod(method);
if (statusCode != HttpStatus.SC_OK)
{
String message = "error";
throw new ActionException(message, "error");
}

byte[] responseBody = method.getResponseBody();
/*
do password protection with iText
*/
out = response.getOutputStream();
out.write(responseBody);
out.flush();
out.close();
} catch (IOException e) {
e.printStackTrace();
} finally {
method.releaseConnection();
}

/*==========in the myDemoReport.rptdesign ===========*/
var request = reportContext.getHttpServletRequest();
cookys = request.getCookies();
if( cookys ) {
testcook = "Cookies:: ";
for( uu=0; uu < cookys.length; uu++ ){
testcook += cookys[uu].getName() + " :: " + cookys[uu].getValue();
}
}else{
testcook = "No cookies";
}
this.valueExpr=testcook;

Hi,

solved the problem. I was using servlet filtering.
