Rijndael encryption

[Eugen Feraru]

Hello,
I am looking at using the Rijndael cryptography class on the dot net side,
and the use a peer algorithm written in C language. It is not clear to me -
by reading the Advanced Encryption System (AES) based on Rijndael - how is
the IV (initialization vector) part of the algorithm. The spec talks about
an Input and a Cipher Key, and does not specify anything about an
initialization vector.

I would greatly appreciate feedback.

Thanks,
Eugen

Think of the IV as a seed. Its just a bunch of random bytes that gets
combined with the first block of your data.
