Hello,<BR>
<BR>
I am trying to use pycrypto to decrypt a file using AES in CTR mode. Currently I have a file with a counter value store in the first 16 bytes of the file. I see in most of the examples the first 8 bytes are stored in the counter value as part of a prefix with the last section starting with zero and incrementing up. My question is that if I want to have a truly random counter value. Do I need to create my own count class to handle the increment or can i use Crypto.Util.counter class.<BR>
<BR>
I am trying to use the Crypto.Util.counter class but i keep getting errors on CTR: counter returned not 16 bytes.<BR>

Thanks,<BR>
