How to encrypt byte array with out padding using RSA in Java?

I've modulus and public exponent as byte[] array, so I'm trying to convert into BigIntegers and then create public key and then Cipher. Here is the example code:
With this I'm always getting different encrypted bytes, is it because of padding. I dont want to use any padding so what parameter I need to pass along with RSA? I've modulus byte[] array size 64 bytes. I believe I'll get 64 encrypted bytes. I've content size of 32 bytes to be encrypted.
--------code begin ---------------------------
BigInteger bexponent = new BigInteger(pubExpo);
BigInteger bmodulus = new BigInteger(modulus);
KeyFactory keyFactory = KeyFactory.getInstance("RSA");
RSAPublicKeySpec pubKeySpec = new RSAPublicKeySpec(bmodulus, bexponent);
RSAPublicKey pubKey = (RSAPublicKey)keyFactory.generatePublic(pubKeySpec);
Cipher c = Cipher.getInstance("RSA");
c.init(Cipher.ENCRYPT_MODE, pubKey);
return c.doFinal(content);
--------code end---------------------------

With this I'm always getting different encrypted
bytes, is it because of padding. Yes, if you're using PKCS1Padding (which is the default in SunJCE if you don't specify it). Have a look at the PKCS1 spec if you haven't seen it already.
http://www.rsasecurity.com/rsalabs/pkcs
Section 7.2.1 talks about type 2 padding, which uses random bytes as the PS string.
I dont want to use
any padding so what parameter I need to pass along
with RSA? NOPADDING. You should be able to find this out by look at the "Supported Paddings" parameter in your provider's database. Which of course, means you'll need to supply the right number of bytes to the Cipher.

  • How to make an array with ActiveX Excel using Excel_RangeSetValue2?

    Hello,
    I want to make an array on Excel. For that, I'm using two functions : Excel_WorksheetGetRange and Excel_RangeSetValue2.
    I write the array on Excel file but only the first case of the array is copied.
    Here, a part of my program :
    char * DataToWrite = {"A", "B", "C", "D"}
    char cCell[10];
    VARIANT             vCell, Data;
    ExcelObj_Worksheet hWorksheet;
    ExcelObj_Range      hRange;
      CA_VariantSetCString (&vCell,cCell);        //cCell = A1:A4
      Excel_WorksheetGetRange (hWorksheet, NULL, vCell, CA_DEFAULT_VAL, &hRange);
      CA_VariantSetCString (&Data,DataToWrite );
      Excel_RangeSetValue2 (hRange, NULL, Data);
    Here what I obtain when I'm compiling on Excel file :
    A
    A
    A
    A
    Solved!
    Go to Solution.

    You should use other instructions to fill the range of cells:
    strcpy (msg, "A1:A4");
    CA_VariantSetCString (&MyVariant, msg);
    Excel_WorksheetRange (ExcelWorksheetHandle, NULL, MyVariant, CA_DEFAULT_VAL, &ExcelRangeHandle);
    Excel_RangeActivate (ExcelRangeHandle, NULL, NULL);
    // Create a SafeArray from array of data
    CA_VariantSet2DArray (&MyVariant, CAVT_CSTRING, righe, 1, array);
    // Transfer data to Excel range
    Excel_SetProperty (ExcelRangeHandle, NULL, Excel_RangeValue2, CAVT_VARIANT, MyVariant);
    ClearObjHandle (ExcelRangeHandle);

  • I have like five GB's of ghost data (data the device claims is not there but it is still taking up space) on my I pad 2 from a failed movie download attempt. How do I fix that with out resting my iPad? I have only 1GB left of storage

    I have like five GB's of ghost data (data the device claims is not there but it is still taking up space) on my I pad 2 from a failed movie download attempt. How do I fix that with out resting my iPad? I have only 1GB left of storage
    The movie had gotten to the point that I could watch it all the way through but it still said processing and got stuck at that point and when I turned off the wifi to try to restart it, it deleted its-self but did not free up any of the storage It was taking up
    Restarting my iPad does not help
    Some thing similar also happened to my old laptop when trying to download the iOS 5 update to my laptop when it came out. It kept getting disconnected and every time it would try to start over and act like what had already been downloaded was not there though it was still taking up the storage space.
    And it continued repeating until it took up all of my storage space. The data file would not show up anywhere so I had to restore my laptop to the factory settings and that worked for awhile but I eventually had to get a new laptop.

    Did you try to set it up as new device, as explained in this article?
    How to erase your iOS device and then set it up as a new device or restore it from backups
    If this does not work, use iTunes to set it back to factory settings, which would also install the latest software:

  • How to add byte[] array based Image to the SQL Server without using parameter

    how to add byte[] array based Image to the SQL Server without using parameter.I have a column in table with the type image in sql and i want to add image array to the sql image column like below:
    I want to add image (RESIM) to the procedur like shown above but sql accepts byte[] RESIMI like System.Drowing. I whant that  sql accepts byte [] array like sql  image type
    not using cmd.ParametersAdd() method
    here is Isle() method content

    SQL Server binary constants use a hexadecimal format:
    https://msdn.microsoft.com/en-us/library/ms179899.aspx
    You'll have to build that string from a byte array yourself:
    byte[] bytes = ...
    StringBuilder builder = new StringBuilder("0x", 2 + bytes.Length * 2);
    foreach (var b in bytes)
    builder.Append(b.ToString("X2"));
    string binhex = builder.ToString();
    That said, what you're trying to do - not using parameters - is the wrong thing to do. Not only it is insecure due to the risk of SQL injection but in the case of binary data is also inefficient since these hex strings are larger than the original byte[]
    data.

  • How to add Excise item with out chapter id

    Dear all,
    How to add Excise item with out chapter id?
    Chapter id of purchae items will be known only after receiving Invoice/gate pass/delivery  chalan from supplier/vendor
    To send a purchase order we need to create that particular item in the master, but with out assigning chapter id system is  not allowing to save without chapter id.
    How to solve this?
    I am with SAP 8.8 and PL 10
    Thanks in advance
    regards,
    Kumar

    Hi Kumar,
    Refer the book of chapter ID or find out on internet you will get the chapter ID.
    Still if you not able to get  the chapter id then consult with excise advisory.
    But you can add Excise PO until you have the excise details in Item master.

    Dear Sameer,
    Please go to transaction VT01N here you enter Transportation planning point and shipment type then press enter.
    Now system will take you to the shipment document creation screen here you click on Select deliveries or press F6 now system will take you to the select outbound deliveries screen in this screen you enter selection data then execute, now deliveries will get assigned to that shipment.
    After assigning the deliveries enter the remaining data then complete the shipment finally save the shipment document.
    For more information please go through this SAP help link
    Note:- Shipment process need to be carry out for the deliveries before PGI.

  • How to build a array with high sampling rates 1K

    Hi All:
    Now I am trying to develop a project with CRio.
    But I am not sure how to build a array with high sampling rates signal, like >1K. (Sigle-point data)
    Before, I would like to use "Build Arrary" and "Shift Register" to build a arrary, but I found it is not working for high sampling rates.
    Is there anyother good way to build a data arrary for high sampling rates??
    Thanks

    Can't give a sample of the FPGA right now but here is a sample bit of RT code I recently used. I am acquiring data at 51,200 samples every second. I put the data in a FIFO on the FPGA side, then I read from that FIFO on the RT side and insert the data into a pre-initialized array using "Replace Array subset" NOT "Insert into array". I keep a count of the data I have read/inserted, and once I am at 51,200 samples, I know I have 1 full second of data. At this point, I add it to a queue which sends it to another loop to be processed. Also, I don't use the new index terminal in my subVI because I know I am always adding 6400 elements so I can just multiply my counter by 6400, but if you use the method described further down below , you will want to use the "new index" to return a value because you may not always read the same number of elements using that method.
    The reason I use a timeout of 0 and a wait until next ms multiple is because if you use a timeout wired to the FIFO read node, it spins a loop in the background that polls for data, which rails your processor. Depending on what type of acquisition you are doing, you can also use the method of reading 0 elements, then using the "elements remaining" variable, to wire up another node as is shown below. This was not an option for me because of my programs architecture and needing chunks of 1 second data. Had I used this method it would have overcomplicated things if I read more elements then I had available in my 51,200 buffer.
    Let me knwo if you have more qeustions

    Hi,
    actually there's none. The UITableView class needs to "know" the tableView's height so either it can calc <number of rows> times <row height> or it has to sum the height of each single row.
    If the row which needs to be of different size always is the first or the last row you can user a tableHeader or tableFoot view.
    Regards

  • How to populate an array with random text files.

    I am making a Jeopardy program. I have my program set up so that it retrieves 5 random text files. I just want to know how I populate one array with all the lines from the text files my program is retrieving.

    You can read a textfile line by line and add each line to an ArrayList. An ArrayList is very much like an array only that it's "open ended". You can start adding lines without first knowing how many you're going to get. If you still want an ordinary "static" array when you're finished reading lines you can easily get one from the ArrayList and then drop the ArrayList.

    how can i get apps with out using credit card info because i do not have a card ?

    Yo Chris. I've been following your answers to different threads and quite frankly, you're very keen in answering everybody regarding this stupidity that Apple has brought upon its customers. Kudos to you. But the problem is, most of the time, in some devices, your solution doesn't work because the NONE option is not there. The same goes for me.
    Meanwhile, I found a temporary workaround for the iPhone 4s, iPad 2 and iPod Touch 4th Gen.
    Register a free Apple ID from the iCloud Settings.
    Go to Settings>iCloud>Account>Tap Payment Information on the Storage Plan Category.
    Fill in the other boxes and choose "None" on Credit Card Information.
    That's it! Hope I helped those who still couldn't find the "None" Option.
    Must be running IOS 5.0.1 though, else there would be no iCloud.
