Jason,
IV size is cipher-dependent, and it usually equals to cipher's block
size, e.g DES is 64 bit block and AES is 128 bits block.
Both AES-128-CBC and AES-256-CBC use 128 bits IV. Original AES can
support various block size in its submission to competition to standard
cipher, but it only suppo
I was reading the OpenVPN security overview which states that an
Explicit IV is used to ensure that two packets with the same plaintext
do not encrypt to the same ciphertext. However, the Overview did not
state the size of the Initialization Vector. I found this page
