1526 bytes

Hi,
I'm new to Java. I have an encrypted string which was encrypted with Delphi
routines and saved to my database.
I'm trying to decrypt it by using Java.
I encrypted that string by XOR with an array of bytes. lets say byte[] =
{1,2,3}. How can i decrypt it?
I tried sth like this:

int[] myKey = {1, 2, 3};
byte[] myEncryptedBytes = myEncryptedStr.getBytes();

 for (int Index = 1; Index <= EncryptedBytes.length; Index++) {
      myDecryptedBytes[Index - 1] =  ((myEncryptedBytes[Index - 1] & 0xff) ^
myKey[Index % 3]);
}

how can i convet byte[] myDecryptedBytes to String? So that i can compare it
with my check string.

thanks,
