byte[] encryptedDataByte = encryptedData.getBytes();
byte[] enbytes = encryptedData.getBytes();Right here. This gets "encrypt" as a String, and tries to get the ciphertext as that String's bytes. You can't do that. String does horrible, horrible things to ciphertext.
If you're going to transmit ciphertext as strings, you need to use Base64 to encode it before transfer, and then decode it after, to get your ciphertext back.

Javax.crypto.IllegalBlockSizeException help?

I am making a plain text encrypt/decrypt program for personal use.
It will compile just fine, but if I try to run the decryption part, it freaks out on me.
It keeps on saying:

This is my code. I cannot figure out what is wrong...

Could this be an IV error?
Can negative IV's be used?
Edited by: eric_smith on Jan 6, 2010 9:25 PM
Edited by: eric_smith on Jan 7, 2010 9:51 AM

I turned this:
String recovered = new String(c.doFinal(input));into this:
String recovered = new String(input);and used 0's for the key and iv and the text was 'decrypted'.
Something tells me the problem is in the output and input cipher.init()
Can someone enlighten me as to what I am doing wrong?
EDIT: btw, the code came from the input method.

Very urgent : please help !!!! Blowfish problem

Greetings people,
I have devised an application which reads the value from file and encrypts it (using Blowfish)......The file is then read and decrypted accordingly..............
Problem : I seem to be able to encrypt and further decrypt file(s) which size is below 100 bytes. Anything beyond that will trigger the following :
javax.crypto.IllegalBlockSizeException: Input length (with padding) not multiple of 8 bytes

The error message says it all.
Input length (with padding) not multiple of 8 bytes
As you are using PKCS5Padding you will have an output data whose length is padded with 1 a 8 bytes. For instance, if your original data have 1023 bytes, it is padded with 1 byte - total length = 1024. It your original data have 1024 bytes, it will be padded with 8 bytes (not 0 as you could think).
You have some problem encoding and decoding Base-64 - it is not yielding the original encrypted results. Your best friend is System.out.println of the length of the original and encrypted data.

Javax.crypto.IllegalBlockSizeException: Input length must be multiple of 8

Hello!
I have encrypted/decrypted one String with DES. I tried to do so on one computer and it seams to work fine. But what I realy want is to encrypt 3 String: username, id, and password, and send them to server. On server I want to decrypt them, and use them to check in database if the person exist. I save this 3 String in an ArrayList, and use ObjectInput/OutputStream to send and receive. Here is some of my code(I hope it is enough for you to help me solve this problem,othervice I will send more).

Urgent please help, this program should work

Urgent please help.
I need to solve or I will be in big trouble.
This program works at my home computer which is not networked.
The hard disk was put onto another computer at another location whihc is networked. Here my program worked on Monday 14 october but since for the last two days it is not working without me changing any code. Why do I receive this error message???

foolishmatt,
The code is quit large.
to understand the program I think all the code needs to be examined.
I would need to send to you in an email.
Here is my e-mail
[email protected]
if you contact me than I can send the code to you.
Thank you in advance.

Javax.crypto.IllegalBlockSizeException,javax.crypto.BadPaddingException

You are very lucky to get this working at all, even on Windows! You encrypt the whole of your string at one go and write it to a file using
fileOutput= new BufferedWriter(file);
dataBytes = text.getBytes("UTF8");
encBytes = encrypt(dataBytes, key, xform);
String encStr = Base64.encode(encBytes);
fileOutput.write(encStr);
fileOutput.close();but you then try to decrypt it a line at a time using
while ((enText = fileInput.readLine())!=null)
byte[] decrypted = Base64.decode(enText);
decBytes = decrypt(decrypted, key, xform);
decrystr=new String(decBytes,"UTF8");
System.out.println("decrypted string token , "+decrystr);
fileInput.close();This just does not make sense. If you encrypt all at one time you must decrypt all at one time.
Your code happens to work because the Base64 encoding puts everything on one line. The fact that this seems to work does not make it correct.
P.S. Your code works on my Linux FC5 so I have no idea why you get the exceptions!

Javax.crypto.IllegalBlockSizeException: 6 trailing bytes

Hi everybody!
I'm facing a error when i try to encrypt a string with symmetric algorithm DES. I try to run the following code on Redhat:
byte[] data="It is a test!".getBytes();
     Cipher cipher = Cipher.getInstance(algName);
     cipher.init(Cipher.ENCRYPT_MODE, key);
int blocksize=cipher.getBlockSize();
     System.out.println("--------blocksize: "+blocksize); // blocksize=8
     byte[] cipherByte = cipher.doFinal(data); // 52 line
The error showing is:
javax.crypto.IllegalBlockSizeException: 6 trailing bytes

Can any one support.
Thanks and waiting your replies.

It would help if you showed the content of the String referenced by 'algName' since it looks to me like you are using "DES/ECB/NoPadding" and not either "DES" or "DES/ECB/PKCS5Padding".

That was all that there was in the most recent one, how long do you think it could take to fix?

Encrypting and Decrypting Data(Its Very Urgent, Please Help.)

Hi,
Can anyone tell me some idea in the below mentioned details.
Iam creating a Function for Encrypting and Decrypting Data Values using
DBMS_OBFUSCATION_TOOLKIT with UTL_RAW.CAST_TO_RAW by using
Key Value as normal.
But the problem, is it possible to have the key value more than 8.
Its showing me error when i give the key value less than 8 or more than 8.
Can u tell me why it happens, is that the limit of the key value or is any other way to do that.
Its Very Urgent, Please Help.
Thanks,
Murali.V

Is this what you're looking for?
Usage Notes
If the input data or key given to the DES3DECRYPT procedure is empty, then the procedure raises the error ORA-28231 "Invalid input to Obfuscation toolkit."
If the input data given to the DES3DECRYPT procedure is not a multiple of 8 bytes, the procedure raises the error ORA-28232 "Invalid input size for Obfuscation toolkit." ORA-28233 is NOT applicable for the DES3DECRYPT function.
If the key length is missing or is less than 8 bytes, then the procedure raises the error ORA-28234 "Key length too short." Note that if larger keys are used, extra bytes are ignored. So a 9-byte key will not generate an exception.

Date format Problem in OAF R12 Urgent Please help!!!

We have acustom application in OAF which was developed in 11i. Now we migrated the same to R12.
In this there are two date fileds getting dispayed on the page and the query for the same is
SELECT TO_CHAR (SYSDATE, 'dd-mm-yyyy') AS CURRENT_DATE, UPPER (TO_CHAR (SYSDATE - 10, 'mon-yy')) AS g_period, UPPER (TO_CHAR (SYSDATE + 5, 'mon-yy')) AS gnext_period, TO_CHAR (sysdate,'dd-mon-yyyy') as today_date, TO_CHAR (sysdate - 1,'dd-mon-yyyy') as yesterday_date FROM DUAL
In 11i version the output is dispaying correctly but in R12 the current date is dispayed as
Start Date 04-Nov-5242
End Date 04-Nov-5241
As per logic it should be
Start Date 09-Feb-2012
End Date 10-Feb-2012
Please help..Urgent issue.

Here are the answers to your problems :
1. Once u restart , the oracle services and the database is not mounting automatically.That is because, when you install the Oracle Oracle8i Standard Edition Release (8.1.7), the two key services namely
OracleOraHome81TNSListner and
OracleService<your SID name>
are configured as manual start ( check the NT --> start>setting>control panel>services. )
For the database to start automatically the next time you start your machine, these two services will have to be put into "Automatic Start" mode.
< for this double click on the respective service, select the "Automatic" radio button and click on ok>.
Now when you restart the machine, your database will be automatically mounted.
2. this as explained above is a corollory to the above problem. you can start or stop your database on NT using the "Services" window....
hope this helps.
bye.

Set Page "HEIGHT" ---Very Urgent, Please Help me on this issue. Please.

Hi all ,
Very Urgent, Please Help me on this issue.
when_now_form trigger i set set maximize the window and MDI. And my window and canvas is same height (1500). The formsweb.cfg also changed to 1500. But still I can not view full page on web. Where to I change the properties. Please help.

Is your form running inside the browser window (with SeparateFrame=False)? If the browser is maximized, and your form is maximized, yet you cannot see the entire screen, you can run with SeparateFrame=True. You can do that on the browser line.

Javax.crypto.IllegalBlockSizeException: Input data length not a multiple

Hi All ,
M worknig with NWCE 7.1.1. I have written code for decryption for decryption. Earlier my web dynpro application was on CE7.1. We migrated it to CE 7.1.1 just week ago after migrating to CE 7.1.1 , on execution of decryption code m gtting as
javax.crypto.IllegalBlockSizeException: Input data length not a multiple of blocksize
i have written following code for decryption.
public String decrypt( String encryptedString, String encryptionKey )
     String UNICODE_FORMAT = "UTF8";
     try
          if ( encryptedString == null || encryptedString.trim().length() <= 0 )
               throw new IllegalArgumentException( "encrypted string was null or empty" );
            byte[] keyAsBytes = encryptionKey.getBytes(UNICODE_FORMAT);
            keySpec = new DESKeySpec(keyAsBytes);
            keyFactory = SecretKeyFactory.getInstance( "DES" );
            cipher = Cipher.getInstance( "DES" );
          SecretKey key = keyFactory.generateSecret( keySpec );
          cipher.init( Cipher.DECRYPT_MODE, key );
          BASE64Decoder base64decoder = new BASE64Decoder();
          byte[] cleartext = base64decoder.decodeBuffer( encryptedString );
          byte[] ciphertext = cipher.doFinal( cleartext );
          return new String( ciphertext );
     }catch (Exception e){
          IWDMessageManager messageManager = wdComponentAPI.getMessageManager();
          messageManager.reportException("Error while Decryption");
          e.printStackTrace();
          return "";
This code was working fine in CE 7.1 . After migrating to CE 7.1.1 it started giving this error.

Thank you for your answer
how the code is usedI have hardcoded key, example
byte[] key = "123456789abcdefg".getBytes();and String for crypt (Example, String in = "green";)
Then I encrypt string in with code above (in qwestion body) and get exception IllegalBlockSizeException: Input data length not a multiple of blocksize
String encrypt(String in) throws Exception{
String out="";
byte[] key = "123456789abcdefg".getBytes();
Cipher ecipher = Cipher.getInstance("AES");
ecipher.init(Cipher.ENCRYPT_MODE, new SecretKeySpec(key, "AES"));
byte[] utf8 = in.getBytes("UTF8");
byte[] enc = ecipher.doFinal(utf8);
out = (new sun.misc.BASE64Encoder().encode(enc)).toString();
return out;
}Clients use JRE1.4 or high. I have JRE1.4 and all work correctly. Also, many clients have 1.4, but only part of they get exception. Code is in the server (this is part of servlet)
This function run in one thread and doesn't use shared resources

R2_AQ_JMS MDB deployment Error--Urgent, please help!!

Deploy a simple MDB to Oracle9iASR2, follow the steps:
1. Define the MDB in ejb-jar.xml
<message-driven>
<description>MDB Queue Listener</description>
<display-name>QueueListener Message Driven Bean</display-name>
<ejb-name>QueueListenerMDB</ejb-name>
<ejb-class>mdb.QueueListenerMDB</ejb-class>
<transaction-type>Container</transaction-type>
<message-driven-destination>
<jms-destination-type>javax.jms.Topic</jms-destination-type>
</message-driven-destination>
</message-driven>
2. Modify the orion-ejb-jar.xml
<message-driven-deployment
name="QueueListenerMDB"
destination-location="jms/SalesTopic"
connection-factory-location="jms/theTopicConnectionFactory"
subscription-name="MDBSUB"
>
</message-driven-deployment>
3. define the resource-provider in application.xml
<resource-provider class="oracle.jms.OjmsContext" name="SalesJMS">
<description> OJMS/AQ </description>
<property name="url" value="jdbc:oracle:thin:@dell2400:1521:mydb"></property>
<property name="username" value="user"></property>
<property name="password" value="pssword"></property>
</resource-provider>
4. Deploy the ear file and got the following error:
java.lang.NullPointerException

at com.evermind.util.ThreadPoolThread.run(ThreadPoolThread.java:64)
Any idea on what's the cause of this. It seems that the Oracle 9i's support of MDB differs significantly from R1. The demo sample that works for R1 no longer work for R2. For example, the following DD doesn't seem to work with R2.
<resource-ref>

</resource-ref>
<resource-env-ref>

Please help!! This is very urgent! Thanks in advance!
