• NoClassDefFoundError with Bouncy Castle Library

  Hello

  I build and preverified Bouncy Castle bccore and bcpkix libraries and included in a BlackBerry project in Eclipse using the 7.1.0 plugin SDK BlackBerry.

  When you try to instantiate the CMSSignedData class I see a NoClassDefFoundError exception throw.  The exception returns nothing of getMessage() and printStackTrace() shows simply "no trace of the stack.

  Any ideas?

  Thank you.

  The problem is now resolved.  When there is a problem with the help of the Bouncy Castle code (even with it included directly in the source code in my test application) attached to the BB JDE 7.1.0.  Rebuild the project against the BB JDE 7.0.0 solves the problem.

• Wireless LAN on Equium A210-1AS connection with WPA-TKIP encryption problem

  I have a 1AS Equium A210 with Vista but cannot connect to the internet via a wireless router cable modem NTL using WPA-TKIP encryption and 5600 philips.

  The laptop shows the base station wireless with a beep sound intense but said that the base of the station is not responding or is hidden when I try to connect to the internet.

  I'm using the correct password.
  I am able to connect to the internet via the base station when connected via the ethernet cable. Other old computers connect wireless with no problems.

  I heard that some combinations of chipsets with Vista can be the cause of some of these issues.

  Clear advice or ideas on what I could try to get wireless internet would be greatly appreciated.

  Have you checked to connect the laptop to the router WLan with WPA encryption settings? Please do. You must disable the WLan encryption to test the WLan connection

  If the laptop could connect properly, then encryption is certainly the reasons why the laptop can not establish the WLan.

  Maybe your wireless network card does not like this on the encryption support or you simply have to update the Windows operating system and the driver WLan.

• zBook 15 - SSD encryption problem

  Good afternoon everyone,

  I get the error message below.

  "An error occurred during initialization authentication pre-seed. (0x9a00).

  The problem is the following:

  1. Image, pushed to the machine using the Clonezilla software. It is a standard construction we have on most laptops.
  2. On-board HP encryption enabled. Recovery stored on USB key.
  3. Laptop has been used for a few weeks.
  4. Someone tried to install software of BeCrypt encryption on the machine.
  5. This, as expected (I wish they'd asked first), completely messed up the machine.
  6. When starting, we still got the encryption authentication screen. After the password, he would try to start windows and BSOD.
  7. To try to remedy the situation, I entered the password encytption and before she started windows, open a CMD window.
  8. Using DiskPart I wiped the drive and reinstalled Windows 7 from CD.
  9. The machine worked, would start through encryption (password entered as usual) and then in the new installation of Windows 7.
  10. Thinking that everything was OK, I relayed the Clonezilla image once more (without disabling the encryption)
  11. The machine now give the error at the top of the pole and the recovery key refuses to play ball

  No matter what anyone thinks could work to solve this problem and save the SSD?

  Thanks in advance

• XTEA encryption problems

  I'm trying to implement the XTEA encryption for a project, but the values that I receive does not correspond really. Is there a known problem with this implementation

  I managed to solve the problem. The encryt implementation, mentioned in vi is false, and all you have to do is to remove the forloop and send data directly key.

  Dell support has finally got to level 3 or 4 they and used a (locksmith) program files unlocked.  The laptop will have to be re-partitioned, reformatted and windows reinstalled to the laptop on the right.  It works but has errors at startup and do other functions but not terribly annoying because the files could be recovered without encryption.

• Encrypted problem

  Mr President, I got Windows7 installed on my machine. I have some encrypted files by using the right click. Then I got Windows7 and again once installed. But now I am unable to access. It shows that you don't have the permission to access. Help, please

  BitLocker is good. It does not distinguish between a foreigner and you. You have a certificate or you can't read encrypted files (which is exactly what you had in mind when you your files encrypted). Take a look at this thread Bitlocker topic:

  http://social.answers.Microsoft.com/forums/en-us/w7security/thread/19f28028-EACE-4878-b5e5-8cd78c19f6f3

  The only way you'd be able to use your encrypted files would be if you have saved your file recovery certificate and your certificate of personal encryption (and private keys) and the data recovery agent certificate to regain access.

  I wanted to know from someone who has this model, if the problem is present.
  Thank you

  Hello

  I put t have it, but best friend of my girlfriend had it and I installed and configured this machine so I got it in my hands and I must say that the keyboard is OK, and I didn't notice anything unusual.

  Also, talk with your local dealer to return option. In my country I have 14 days to return the product if I don't like it. Maybe you have the same option in your country. Check it out.

  In any case, I must also say that the Satellite Pro L670 is good laptop for all activities of the day. Nice design, very good material and enough power/performance. With other words: nice piece of hardware for the money.

• TECRA M2 and WPA/WPA2 encryption?

  I use a Macintosh Time Capsule as a router, but cannot connect with a Tecra M2 with card Intel (R) PRO/Wireless 2100 has LAN Mini PCI Adapter. The router uses WPA/WPA2 encryption? Why am I not able to connect?

  When I click on the network (which appears on the available networks), he doesn't want the network key.

  What is an encryption problem? This computer with this card cannot support encryption WPA/WPA2?

  In the wireless connection settings, you should see what Wlan encryption is supported by the wireless network adapter
  If the WPA/WPA2 encryption is not listed it then you will not be able to use it.

  In this case, you must change the encryption on the router WLan or will need to purchase an external Wlan (WLan USB key) that would support the WPA/WPA2 encryption.

• Plain AES using

  Hi all

  I have to use AESEncryptorEngine.encrypt () to encrypt data using the AES algorithm. But the times when I have try it, BB throws IllegalArgumentException. There is no detailed in the exception message and stacktrace.

  I've seen examples where CBCEncryptorEngine & operated PKCS5FormatterEngine with AESEncryptorEngine. It works fine, but I need to use only the AES and without fill.

  What is the wrokaround for this?

  Can you suggest me some third party encryption library. I tried the J2Me of Bouncy Castle version, it is not compiling in BB.

  Thank you.

  I think the problem here is plain and encrypted text must match the length of the block for the algorithm.  So do both these 16 bytes and do this test one another.

• Compilation of obscured using CAP jar file

  Hello

  I have the following problem:

  -J' have a midlet application that uses Bouncy Castle for cryptographic operations.

  -Bouncy Castle defines classes Java, java.io.FilterOutputStream, etc. in his jar.

  -To compile this code I use aggressive obfuscation so that package names are also obfuscated, otherwise the application will not build.

  -J' use Java Platform Micro Edition SDK Version 3.0

  -I want to generate a file of cod for the deployment of Blackberry using the CAP directly from the jar/jad file.

  -I do not use a specific product of the rim api.

  -I'm not using the - import in the CAP command option.

  -When I run the CAP tool, I get a bunch of warnings saying:

  java.lang.String: WARNING! : not found definition

  java.lang.Throwable: WARNING! : not found definition

  Finally, I get the error:

  Error! : class: java.lang.String has no members: equals

  What's not here?

  Hello

  Thanks a lot to all of you for your help. Actually I just tried add import = net_rim_api.jar to my options of Cap.

  Which seemed to have solved the errors/warnings of compilation.

  But right now I'm stuck with another question. In other words, when I try to install OTA application hosted on my web server for the Simulator I get an error "failed to save the Push 911." Any idea? My application uses a registry to statically recorded.

  Thank you

• XP Remote Desktop can only connect to Vista once by restarting: error 0xc00002fd

  I am running XP SP3 and by connecting to a computer running Windows Vista by using RDP 6.1 (also tried 7.0) with NLA.  I did the configuration of the registry for SINGLE sign-on (although it reproduced without these registry entries with new credentials).  The first logon works perfectly.  That I disconnect the Vista machine.  Then the second connection comes with "an authentication error has occurred (0xc00002fd)."  I can never get another connection to work.  I reboot XP and it works again, once.  The error seems to be a sort of encryption problem.  If CredSSP is cached something that does not work?  Any help is greatly appreciated!
