And if anyone want to verify that it does.

Just do:

$ mcr ssl1$exe:openssl enc -aes-256-cbc -k MySuperSecretPassPhrase -P 
-md sha1

on your favorite OS a few times.

I got:

iv =0E38C5B4A04DAD98965D95161268ECDB
iv =51D9A670DEB1BF1E56745D28A6441A3C
iv =26E6C8F59628C12A7A4EBFC3BF340727
iv =E4609B2D4AFD0B8190101A87F8CA83DB
iv =9350E05D92C0915B229048B251E3C663

They look quite different to me.
