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?
