hi,Ladislav!
Thanks a lot for your response.
Yes , I use block mode cipher to encrypt file data.
I dont know how to use counter-mode cipher.
What is the difference between couter-mode and block mode?
To make the encrypt device transparent ,I cant force the encryted files
aligned to
8 bytes.

You are using block mode cipher, right ?
Block length for DES is 8 bytes.
Use a counter-mode cipher or make your
encrypted files aligned to 8 bytes.
