I haven't made it through your crypto challenges, so perhaps someone could explain this to me

https://github.com/mothran/bunny/blob/master/proposal.txt :

> To detect a bunny specific packet, each outbound packet is resized to match pre determined pack_len % mod = remainder values. Then when looking for packet bunny just tests each packets length against the modulus and remainder values.

https://github.com/mothran/bunny/blob/master/libbunny/SendRe... :

    if (round( (size - 4) % MODULUS, 2) == REMAINDER):
        print "pack num: %d, " % n 

https://github.com/mothran/bunny/blob/master/libbunny/config... :

    MODULUS = 1.21
    REMAINDER = 0.85

What?!
