Hi,

How do I Generate AES key with seed value so that whenever I generate key with same seed value,I shud be able to get the same AES key?
Please help.

Thanks.

net.rim.device.api.crypto.AESKey(byte [] data) or other similar constructors.

Yes,I have used the same.
Actually,whenever the encrypted text is generated,its different everytime.How can I generate same encrypted text everytime?

How are you encrypting the data? I used this KB article to start.

Hi,
Thanks for reply.
I am encrypting data in follwing manner:


System.out.println("Message to be encrypted >>> "+message);
AESKey key = new AESKey();
byte [] aesByte = key.getData();

AESstring = new String(aesByte);

AESEncryptorEngine encryptionEngine = new AESEncryptorEngine(key);

PKCS5FormatterEngine formatterEngine = new PKCS5FormatterEngine( encryptionEngine );

ByteArrayOutputStream outputStream = new ByteArrayOutputStream();

BlockEncryptor encryptor = new BlockEncryptor( formatterEngine, outputStream );

encryptor.write( message.getBytes() );

encryptor.close();

encryptedData = outputStream.toByteArray();

Well, there's your problem. from the API documentation AESKey() "Creates a new random 128-bit key". So it is not surprising that you get different cyphertext each time.

Hi again,
Coming back to my previous thread...

I am not able to generate AES key with AESKey(keyData) .

Also whenever I print it either in the form of String or byte[] , I am not able to generate it.(print it) Actual key is never printed.

What can be done to get the key?

Please help,badly stuck in this issue.
