Better Encryption/Decryption Method - SMIME or PGP ?

1. Which is the default encryption/decryption method provided in BizTalk Server ?
2. What is PGP Encryption/Decryption ?
3. What is SMIME Encryption/Decryption ?
4. Which is better out of the two ?

There is no default encryption/decryption method provided in BizTalk Server. BizTalk uses encryption/decryption using certificates (when you use certificates ). More about them here.
BizTalk Server : Encrypting and Decrypting a Message.
Pretty Good Privacy (PGP) is a data encryption and decryption computer program that provides cryptographic privacy and authentication for data communication.
Soruce: Wiki. In Specific to BizTalk, messages are encrypted/decrypted at the entry point into BizTalk, right place is in pipeline using custom pipeline component. There is one available
which you can learn more here.
https://code.msdn.microsoft.com/windowsdesktop/BizTalk-Sample-PGP-ebcbc8b2. Also there is a thrid party adapter and pipeline component available to implement extensive suite of PGP features in BizTalk-
https://www.eldos.com/bizcrypto/biztalk-pgp-adapter-pipeline.php
S/MIME (Secure/Multipurpose Internet Mail Extensions) is a standard for
public keyencryption and
signing of MIME data. S/MIME is on an
IETFstandards track and defined in a number of documents, most importantly RFCs 3369, 3370, 3850 and 3851. S/MIME was originally developed by
RSA Data Security Inc.
soruce Wiki. In BizTalk, when you use certificates with two-key security, it supports public key encryption of outbound messages and decryption of inbound messages based on Secure Multipurpose
Internet Mail Extensions (S/MIME). BizTalk Server uses S/MIME version 3 for encryption of outbound messages, and S/MIME versions 2 and 3 for decryption of inbound messages. Reference:
http://msdn.microsoft.com/en-us/library/aa559843.aspx
When you discuss about which is more native, I would choose S/MIME which can be implemented with certificates and out-of-MIME pipeline components.

Best method for encrypting/decrypting large XML files ( 100MB)

I am in need of encrypting XML for large part files that can get upwards of 100Mb+.
I found some articles and code, but the only example I was successful in getting to work used XMLCipher, which takes a Document, parses it, and then encrypts it.
Obviously, 100Mb files do not cooperate well with DOM, so I want to find a better method for encryption/decryption of these files.
I found some articles using a CipherInputStream and CipherOutputStreams, but am not clear if this is the way to go and if this will avoid memory errors.

}This looks like it might fit, but there is one more twist, I am using a persistence manager and xml encoding to accomplish that, so I am not sure how (where) to implement this method without affecting persistence.
Any guidance on what would work best in this situation would be appreciated.

vbplayr2000

I can give some general guidelines that might help, having done much similar work:
You have 2 different issues, at least from my reading of your problem:
1) How to deal with large XML docs that most parsers will not handle without memory issues
2) Where to hide or "black box" the encrypt/decrypt routines
#1: Check into XPP3/XMLPull. Yes, it's different that the other XML parsers you are used to using, and more work is involved, but it is blazing fast and can be used to parse a stream as it is being read. You can populate beans and process as needed since there is really not much "inversion of control" involved compared to parsers that go on to finish the entire document or load it all into memory.
#2: Extend Serializable and write your own readObject/writeObject methods. Place the encrypt/decrypt in there as appropriate. That will "hide" the implementation and should be what any persistence manager can deal with.

Encrypt External Drive with TrueCrypt / PGP Signature

I want to use TrueCrypt to encrypt an external drive. I understand the new version of FileVault can do this but I prefer not to upgrade to Lion. I'd rather wait till Mountain Lion comes out later this year.
For those who have used both...Just wondering how TrueCrypt compares to FileVault in regards to encrypting an external drive.
Also, I am trying to install or execute the PGP Signature to ensure that the TrueCrypt software that I am downloading from the TrueCrypt's Web site is authentic and has not been hacked.
How do I run or install it? I double-click on the PGP Signature file, a window pops up and says it cannot find an application to open it. I even tried removing the ".sig" from the end of the file name and it say it cannot open the disk image.
There are instructions on the TrueCrypt web site for Windows users but none for the Mac users that I can see.

If you want better, more reliable security on a external drive, you should get a self encrypting external drive, these have a hardware based encryption, either a physical key and/or keypad to enter a password and do all the encryption/decryption on the drive itself.
No need for software means you can take your data to any secure machine and the computer thinks it just another drive. Software can become unrelaible or glitchy, subjected to updates/tampering. Hardwired requires physical possession of the device.
Also there are smalller portable USB thumb drives like Iron Key that also self-encrypt and have the advantage of being quickly discarded upon a threat.

You haven't replied but I guess I haven't answered your question either...
Sure it works but from a LV programming standpoint it is very redundant and Rube Goldberg like.
IMHO you should scrap what you have or at least clean it up.
I am a long ways from being a LV expert but there are the things that pop right out at me when I see your code.
You use identical code in three places, make it a sub-vi.
Why start with a constant of -1 and increment it once inside your for-loop? This value will always be 0.
Don't use array size to set the number of iterations of your for-loop then use the iteration counter to index an array inside the loop, use auto indexing.
Your block diagram is sloppy and hard to follow.

Encryption/Decryption failure for pdf and MSWord files

Hi,
Is there anybody to help me to find out what is wrong with my class (listing below)? I am sucessfuly using this class to encrypt and decrypt txt, html files but for unknown reasons I am unable to use it for e.g. pdf files. The encrypion somehow works but any atempt to decrypt is a failure.
/* This class accepts an input file, encrypts/decrypts it using DES algorithm and

than 8 is to be passed to the encryptFile/ decryptFile methods. This password is
used to generate the encryption key. All exception handling is to be done by
calling methods. These exceptions are thrown by encryptFile/ decryptFile methods.

Hi,
I found at least one thing wrong. In the decrypt
method you are reading from 'fInputStream_' rather
than 'dataInStream'.
Worked for me on MSWord after changing this!

TRIPLEDES Encrypt/Decrypt in Oracle

We are having issues in oracle encryption/decryption.
In our web application,We receive a number as input from the user which is encrypted & encoded using DES3 in .NET.
This encrypted value is stored in the oracle database. We need to decrypt it in oracle8.1.7 to get
the original number entered by the user.
We are using the following code and facing issues.
declare
decrypted_string VARCHAR2(2048);
input_string VARCHAR2(2048);
begin
DBMS_OBFUSCATION_TOOLKIT.DES3Decrypt (input_string=> hextoraw('a403de8264ec0b60a09c6d115768aff0'),
key_string=>hextoraw('6d6f68616d6d6164616c6c616d6261647368616831323334'),
Decrypted_string=>decrypted_string);
dbms_output.PUT_LINE('vr_decrypted is:' || decrypted_string);
end;
We have taken the string 'hello ho'.
This text is encrypted and encode ni .NET in DES3 which is the input string 'a403de8264ec0b60a09c6d115768aff0'.
and the key is the encoded format of the key used to encrypt the input string.
we are not getting the decrypted value as expected. thats 'hello ho'

If I understand what you are trying to accomplish correctly, a better approach might be to protect your data by encrypting the network traffic between the middle tier and the db. This would ensure the entire sqlnet exchange has been protected and not just any one piece of data. Once the data has been safely moved to the db tier, you can then use the DB Crypto package to encrypt any individual data you want stored in tables protected. Doing it this way will prevent you from having extra Forms application code and prevent you from writing your own risky security routine in Java.
Refer to the Oracle Net Services documentation for information on how to encrypt the net traffic between client and db. Remember that the "client" in this case is the middle tier Forms environment and not the end-user. Here are some helpful references:
http://docs.oracle.com/cd/B28359_01/network.111/b28530/toc.htm

Error in running encryption/decryption using DES in Websphere Dev't Client

Hello!
I have a code used to encrypt / decrypt a string (password). I have already tested it using Netbeans and it is working. But when I tried to add the java code to an existing web project using Websphere Development Client,, javax.crypto.* is not recognized. Then I imported JCE.jar.
The java code contains no errors then, but when I started to run the project, it gives an Error 500. And below is the Console's error message:
E SRVE0026E: [Servlet Error]-[javax.crypto.spec.PBEKeySpec: method <init>([C[BI)V not found]: java.lang.NoSuchMethodError: javax.crypto.spec.PBEKeySpec: method <init>([C[BI)V not found[/b]
Have I missed something to add? Or other things that I should do upon importing this jar file?
Please help.
Advance thanks for your reply.
misyel

I dont know what version of Java that my Websphere's using. But I am very sure that it is outdated. I am using Websphere 5.0. For Netbeans, it is JDK1.5.
I imported the JCE from JDK 1.5 on Websphere.
I think the code works perfectly fine. Actually it was my friend's code for encryption but they are using Eclipse for development (almost the same from Websphere but somehow different from it.)
My idea is that I cant match the versions of the jarfiles used in my project. As much as I wanted to change the imported jar files, I couldn't for when I replaced the existing jar files, more and more errors occur.
can we have any alternative ways of importing the jar files? or is there any other code that might help that will not use the JCE.jar?
I really appreciate your response. thanks

Socket DESede encrypt/decrypt

I have set up a class that contains methods to enrypt and decrypt a byte[] with DESede. This works great. I then created a socket client/server and sent this encypted byte array over the net. I get this error:
javax.crypto.BadPaddingException: Given final block not properly padded
When I go to decrypt ont he other side. despite the length of the two byte[]'s being the same.
Any ideas anyone ??

Yes it does at that. I currently use that.
Here is the code I have for creating the key:
public void createKey(){
if( dezKey == null ) {
try {
     Security.addProvider(new                          com.sun.crypto.provider.SunJCE());
     KeyGenerator keygen =                          KeyGenerator.getInstance("DESede");
     dezKey = keygen.generateKey();
     cyphr =                                    Cipher.getInstance("DESede/ECB/PKCS5Padding");
catch( Exception e ) {
     System.out.println("There is and error intializing the                     provider and cypher");
     e.printStackTrace();
}//End if
}//End public void createKey()
I have standard encrypt and decrypt methods that are will take either a byte[] or string nad successfully enrypt or decrypt. The problem arrises when i send the message of over the net to decrypt. Both sides use a key generated and saved in a third location.
Any ideas anyone??

How to encrypt/decrypt xml data into, and then out of IDS?

Hi,
How would we encrypt NPPI information being passed from an unencrypted xml through IDS, and then decrypt it on exit prior to Gendata.
The IDS SDK gave a reference to IDSEncryptionRule(), but insufficient examples of implementation.
It could be something like a single tag element, or even the entire xml, it's just not clear how to make it happen using native IDS methods.
Any thoughts or help to implement this security measure would be most welcome!
Thanks so much!
Edited by: lodit on Apr 10, 2013 2:56 PM

Hi there,
You would need to write a custom IDS rule that implements this function. You can refer to the IDS SDK book for info on writing a custom rule. IDSEncryptionRule does operations based on the request state received. Normally when an IDS rule is executed, the rules in the request type definition are executed with the RUN_FORWARD request state. Then they are executed with the RUN_REVERSE request state. An example of why this model is used would be the ATCReceiveFile. On RUN_FOWARD, it writes the contents of file segments in a message to a temporary file. Subsequent rules execute. Then on the RUN_REVERSE, the ATCReceiveFile does clean up routines to remove the temporary file.
So, armed with that knowledge, you can use the IDSEncryptionrule to perform on RUN_FORWARD (decrypt message variables for subsequent processing by Documaker) and then on RUN_REVERSE (encrypt message variables to send back to the client).
It should be apparent at this point that you need to use an encryption/decryption mechanism with the IDS client otherwise you won't be able to prepare the message to send or read the response. On the client side there are functions - consult the examples included in the IDS SDK (DSI_DSK in the installer package).

EFS Encryption Decryption Performance

We are currently testing EFS, on a Windows 2008R2 server (VM), to encrypt/decrypt a Windows share containing mostly TIF files. Performance on encryption is fine unfortunately it takes 10+ seconds to decrypt the TIF files
(sizes 50KB to 2MB). When decrypting non-TIF files performance is acceptable. Has anyone experienced this issue and found a solution? Also, Is there another Windows native encryption/decryption solution that has better overall performance?

Hi,
Based on my research,
TIFF is a flexible, adaptable file format for handling images and data within a single file, which can be a container holding compressed (lossy)
JPEG and (lossless)
PackBits compressed images. The slowness of decrypting the .tif files could be caused by its own feature.
You can also try to use Bitlocker to seek for better performance, although Bitlocker is used to encrypt volumes.

As this is sensitive data, i need to decrypt this data ( file i am picking from source system is already encrypted in source directory ) and i need to send it to target system. i found some alternatives like module development and pgp encryption. I am not that much proficient to develop module and i looking at other alternative like pgp. Is PGP is free software?? how can i install and how can i call from my sender adapter?? Please Help.
Thanks

If these things are already done then u need juz few modification in the adapter configuration.

Javax.crypto.BadPaddingException in DES encrypt/decrypt algorithm

I am using DES algorithm, the default provided by J2ME to encrypt and decrypt some text. My problem is that I can encrypt the text but when I decrypt I get javax.crypto.BadPaddingException. I used a sample code from this forum I suppose and modified it to some extend.
Here's the output -
Plain Text :debayandas
Cipher Text :Æ2�Ü°*Yð´4}�f¥
Recovered Plain Text :javax.crypto.BadPaddingExceptionAnd here's the J2ME code -
Declaration part:
private boolean midletPaused = false;
        private static String algorithm = "DES";
     private static byte[] secretKey = {(byte) 0x2b, (byte) 0x7e, (byte) 0x15, (byte) 0x16,
                                                  (byte) 0x28, (byte) 0xae, (byte) 0xd2, (byte) 0xa6 };
     private static String secretKeyAlgorithm = "DES";
     private static byte[] iv = "DES".getBytes();
     private static byte[] plainText = null;
     private Key key = null;
     private static Cipher cipher = null;
     private static int ciphertextLength = 512;
        private static byte[] cipherText = new byte[ciphertextLength];
        private static int decryptedtextLength = 1024;
        private static byte[] decryptedText = new byte[decryptedtextLength];commandAction:
public void commandAction(Command command, Displayable displayable) {
        if (displayable == form) {
            if (command == exitCommand) {
                exitMIDlet();
            } else if (command == okCommand) {
                plainText=textField.getString().getBytes();
                encrypt();
                decrypt();
    } Encrypt:
public void encrypt()
            try
                key = new SecretKeySpec(secretKey,0,secretKey.length,secretKeyAlgorithm);
          cipher = Cipher.getInstance(algorithm);
                cipher.init(Cipher.ENCRYPT_MODE, key);
                cipher.doFinal(plainText, 0, plainText.length, cipherText, 0);
          System.out.println("Plain Text :"+new String(plainText));
          System.out.println("Cipher Text :"+new String(cipherText));
            catch(Exception e)
                System.out.println(""+e);
    }Decrypt:
public void decrypt()
        try
//            cipher = Cipher.getInstance(algorithm);
            cipher.init(Cipher.DECRYPT_MODE,key);
            cipher.doFinal(cipherText,0,cipherText.length,decryptedText,0);
            System.out.println("Recovered Plain Text :"+new String(decryptedText));
        catch(Exception e)
            System.out.println(""+e);
    }Where am I going wrong?

I am asking as there isn't one default implementation in J2ME and as far as I am aware it is not included in any Configurations or Profiles of J2ME.
You might be using [Bouncycastle library|http://www.bouncycastle.org/java.html] or any other third party implementation of DES, in which case please refer to the documentation of it to see in which methods throw BadPaddingException and in what circumstances, in order to pinpoint the problem.

How to resolve bug RC4 encrypt-decrypt on iPAD with AIR15 only

Hi everybody,
I have some trouble with AIR15 only, In the past, I created a small game on iPad It could send or receive messge from server. I used lib as3crypto.swc encrypt or decrypt message (RC4). But when I upgrade to AIR15 encrypt-decrypt cannot work ( Another thing about this crash is that it only happens with a release (adhoc or appstore) build but NOT with a debug build). I check so many time but i don't know what is problem here.
Please help me, thanks so much any advice.
P/S: My game have many swf files (code and resource). I must combine multiple SWF files into one.
Class RC4.as
import com.hurlant.crypto.prng.ARC4;
import com.hurlant.util.Base64;
import com.hurlant.util.Hex;
import flash.utils.ByteArray;
public class RC4
private static const key:String = "keytest";
private static var byteKeys:ByteArray = Hex.toArray(Hex.fromString(key));
private static var rc4:ARC4 = new ARC4();
public static function encrypt(clearText:String):String
var byteText:ByteArray = Hex.toArray(Hex.fromString(clearText));
rc4.init(byteKeys);
rc4.encrypt(byteText);
return Base64.encodeByteArray(byteText);
public static function decrypt(encryptedText:String):String
var byteText:ByteArray = Base64.decodeToByteArray(encryptedText);
rc4.init(byteKeys);
rc4.decrypt(byteText);
return Hex.toString(Hex.fromArray(byteText));

Sorry, exact message is "this movie could not be played".
There are hundreds of posts about this message but no one states a clear solution to the problem.
Your help will be much appreciated.
Thank you.

Help ! Need PCI Encryption/Decryption Controller Driver for New HP 355 G2 (AMD) w/Win 7 Pro 64 Bit

Just rebuilt new HP 355 G2 to Win 7 64 bit. The ONLY driver I can not locate or get to work is the PCI Encryption/Decryption Controller. I installed all latest drivers for this model/OS from both HP and AMD sites still no luck. AMD autodetect utility and Catalyst software installed all other drivers successfully except this one and when completes says all drivers, including chipset, are installed successfully and current.
I am at a complete loss where to get this driver from a OEM site, can you help ?
Device ID's:
PCI\VEN_1022&DEV_1537&SUBSYS_15371022&REV_00
PCI\VEN_1022&DEV_1537&SUBSYS_15371022
PCI\VEN_1022&DEV_1537&CC_108000
PCI\VEN_1022&DEV_1537&CC_1080
Thanks !!!
This question was solved.

Hi:
You need to run this driver and then manually install it.
http://h20565.www2.hp.com/hpsc/swd/public/detail?swItemId=vc_133833_1
To manually install the driver go to the device manager and click on the PCI Encryption/Decryption Controller needing the driver.
Click on the driver tab. Click on Update Driver.
Select the Browse my computer for driver software option, and browse to the driver folder that was created when you ran the file.
That folder will be located in C:\SWSetup\sp66974.
Make sure the Include Subfolders box is checked, and the driver should install.
Then reboot.

Better Encryption/Decryption Method - SMIME or PGP ?
