sending an encrypted byte array through a socket

Hi all,
I'm trying to send an encrypted byte array through a socket. The other side (the client) has to read it and decrypt it. The problem is that the client is not receiving the encrypted byte array correct. Below follows the code I have:
---- sending the encrypted byte array (server side)
byte[] data = "test".getBytes();
byte[] result = cipher1.doFinal(data);
BufferedOutputStream bos = new BufferedOutputStream(connection.getOutputStream());
bos.write(result);
bos.flush();
----- receiving the encrypted byte array (client side)
BufferedInputStream bin = new BufferedInputStream(connection.getInputStream());
byte[] input = new byte[64];
for(int i = 0; i < input.length; i++) {
int b = bin.read();
if(b == -1) break;
input[i] = (byte) b;
}

When I check if input is equal to result, I get a no as answer. Is anything wrong with my code?
Thanks a lot.
Alessandro.

When you decrypt the received bytes, do you decrypt the entire array of 64 bytes? If so, you're adding a bunch of zeros that weren't in the original cyphertext.

If not that, did you compare the two byte arrays to see if you at least received the correct bytes?

You can use in.readFully...
