HI..

I got this wired problem, I'm writing a module to send encrypted
packet over a tunnel.. sort of like freeswan(IPSec), but much simpler.

I use blowfish for encryption and decryption. The problem occures when
which I need to do pad the packet in order to apply blowfish.

Now, my module works if a) no padding needed, b) need to pad even number
of bytes. when I need to pad odd number of bytes, the receiver does not
respond(sender is ping).

I had a sniffer running on the receiver and it shows the receiver does
receive the packet, and decrypted it correctly back to the original
packet. (I dump the packet to the screen on sender before encryption and
on receiver after decryption. they showed up same.)


does anyone know what could be the problem ? I don't understand why
even pad works and odd pad doesn't...


Thanks in Advance..
