I dont know how to use counter-mode cipher.
What is the difference between couter-mode and block mode?

To say the truth, I am not expert to encryption methods
so I can’t explain you the differences. The only difference
I know is that the counter mode cipher is not block aligned.

If you need a counter mode implementation, look
for a free implementation on the net
(e.g. www.libtomcrypt.org)

To make the encrypt device transparent ,I cant force the encryted files
aligned to 8 bytes.

Yes, you can. Another question is if you must.
This is a question of how you’ll design your
encryption software.
