Kleopatra: Decryption failed: invalid data

For encrypting files I use PKCS # 7 and the Javascript bundle forge.pki.
var forge = require('node-forge');
var contentBuffer = forge.util.createBuffer( forge.util.decode64( "fasdasd asdasdasda" ));
var cert = forge.pki.certificateFromPem(certPem);
var p7 = forge.pkcs7.createEnvelopedData();
p7.addRecipient(cert);
p7.content = contentBuffer;
console.log("Encrypt...");
p7.encrypt();
var asn1Cert = p7.toAsn1();
var derBuffer = forge.asn1.toDer(asn1Cert);
var p7mContent = derBuffer.toHex();
console.log(p7mContent);
I copy the hex value into my Java class as a string constant. Java saves then converts this into a .p7m file and stores it locally for me.
public void writeDocumentContent(String filename) throws Exception {
byte[] encryptedMessage = getP7MBytes(hex);
InputStream inputStream = new ByteArrayInputStream(encryptedMessage);
handleTransfer(inputStream, TransferKanal.HTML5);
}
private static byte[] getP7MBytes(String p7m) {
int len = p7m.length();
byte[] data = new byte[len / 2];
for (int i = 0; i < len; i += 2) {
data[i / 2] = (byte) ((Character.digit(p7m.charAt(i), 16) << 4) + Character.digit(p7m.charAt(i + 1), 16));
}
return data;
}
private void handleTransfer(InputStream inputStream, TransferKanal kanal) throws Exception {
String path = "C:TEMP/padline";
createDirectory(path);
String filename = "example." + kanal.getFileExtension();
File targetFile = new File(path, filename);
provideTransferData(inputStream, targetFile);
}
private void provideTransferData(InputStream inputStream, File targetFile) throws Exception {
try (InputStream bInputStream = new BufferedInputStream(inputStream, 20 * 8192)) {
provide(bInputStream, targetFile);
} catch (IOException e) {
throw new Exception("error while reading/writing transfer data", e);
}
}
private boolean createDirectory(String directory) {
File file = new File(directory);
if (!file.exists()) {
file.mkdirs();
return true;
}
return false;
}
private void provide(InputStream is, File finalFile) throws Exception {
try {
File destFile = new File(finalFile.getAbsolutePath());
FileOutputStream buffer = null;
try {
buffer = new FileOutputStream(destFile);
int nRead;
byte[] buf = new byte[2 * 16384];
while ((nRead = is.read(buf, 0, buf.length)) != -1) {
buffer.write(buf, 0, nRead);
}
} catch (Exception e) {
throw new Exception("provision location corrupted", e);
} finally {
if (buffer != null) {
buffer.close();
}
}
} catch (IOException e) {
throw new Exception("error copying file", e);
}
}
Before, I create a bundle of the certificate and the private key via openSSL with following command:
openssl pkcs12 -export -inkey private.key -in public.cert -out certificate.pfx
and imported it into Kleopatra as a .pfx file. Then I have the generated (encrypted) p7m file to decrypt in Cleopatra and pushed the following error message:
Decryption failed: invalid data

I want to print to pdf file in javascript, where outputstream and pdfwriter

I am trying to create a PDF from a server-side controller (report) (ireport) with ajax (and so on), and try to return the data to pdfwriter, servletoutputstream, and httpservletresponse. (I do not know exactly what I'm doing, but I'm doing it this way).
The original purpose was to send a server-side pdf file to the client, find the printer and print without a preview window.
Among them, I wrote 'application / pdf' on the server side and 'datetype: text' on the client side ajax (there is an error if I do not use ajax datatype: text)
If you print the results to the console, they will only be listed as unknown code.
Currently I am trying to put it into an iframe frame.
Question!
1. What should I do to use the text string sent to server -> client as pdf or script code?
(I have already asked you two weeks ago)
2. How do I send a pdf to server -> client? I would like to apply it to the screen by expressing it directly in code instead of downloading it. To print out.

1: Error Image Form Android Server Response

First, try to validate your JSON response in this page for example:
https://jsonlint.com/
If your JSON is correct, then determine if is an array or an object, depends of that use the correct parsing :
If it's an array:
JSONArray array = new JSONArray(your_string_json);
If it's an object
JSONObject object = new JSONObject(your_string_json);

XMLHttpRequest js --> java --> js

i'm using XMLHttpRequest to send a variable from the js file to java file in the same project.
My problem and my question is: how i know my URL ?
Here is my code from js file
xhttp = new XMLHttpRequest();
var handlerFunction = getReadyStateHandler(xhttp, getValue);
xhttp.onreadystatechange = handlerFunction;
xhttp.open("POST",/* Location of my java file */,true);
xhttp.setRequestHeader("Content-Type", "application/x-www-form-urlencoded");
xhttp.send(identMsg);
function getValue (body) {
var valueBody = body.getElementByTagName("body")[0];
}
function getReadyStateHandler(xhttp, responseXmlHandler) {
return function(){
if (xhttp.readyState == 4) {
if(xhttp.status == 200) {
responseXmlHandler(xhttp.responseXML);
} else {alert("Http error: " +xhttp.status);}
}
}
}
and the java code
public void doPost (HttpServletRequest xhttp, HttpServletResponse res) throws IOException {
String body = null;
StringBuilder stringBuilder = new StringBuilder();
BufferedReader bufferedReader = null;
try {
InputStream inputStream = xhttp.getInputStream();
if (inputStream != null) {
bufferedReader = xhttp.getReader();
char[] charBuffer = new char[128];
int bytesRead = -1;
while ((bytesRead = bufferedReader.read(charBuffer)) > 0) {
stringBuilder.append(charBuffer,0, bytesRead);
}
} else {
stringBuilder.append("");
}
} catch(IOException ex) {
throw ex;
} finally {
if(bufferedReader != null) {
try {
bufferedReader.close();
}catch (IOException ex2){
throw ex2;
}
}
}
body = stringBuilder.toString();
res.setContentType("application/xml");
res.getWriter().write(body);
}
what is missing?
EDIT: I need to get URL in the js side.

You can have the URL in js with document.location.href

The SmartSource Data collector JavaScript Tag, could be inserted from Java?

I'm totally new in Webtrends, I have read that The SmartSource Data collector JavaScript Tag, could be inserted from Java or HTML. does anyone know how to inser it from Java, I found the below class, is this class does the job? please provide some samples. Thanks in advance
