PLEASE HELP!!! String conversion problem with BigInteger class

[Gandu]

Could some Java guru please point out what I am doing wrong? I have
created a simple RSA class using java.math.BigInteger. In public
static void main(...) I
have:
RSA rsa = new RSA();
rsa.genKeys();
rsa.showKeys();
String str = new String("This is RSA test");
byte [] byteArray = str.getBytes();
BigInteger bigInt = new BigInteger(byteArray);
BigInteger result = rsa.decrypt(rsa.encrypt(bigInt));
if(result != null){
String str1 = new String(result.toByteArray());
System.out.println(str1);
}

The print statement prints a starnge looking String. However, if I use
BigInteger bigInt = new BigInteger("1234567890");
instead of BigInteger bigInt = new BigInteger(byteArray); in above,
the
output is 1234567890
Could someone please point out what I am doing wrong? Thanks in
advance for
your help.

It shouldn't. Either the code you've posted isn't the one you're
running or it's not that code that does the printing. Or something
is seriously wrong with your RSA code.

The code ypu've posted looks right.
