To build-up trust in the encryption-algorithm, you can verify the encrypted data-files with GnuPG (http://www.gnupg.org) for example.

Just call

$> gpg –-list-packets <datafile>

on command line or test de- and encrypting directly:

$> gpg --decrypt <datafile> > tmp

$> gpg --symmetric --armor --cipher-algo AES tmp

$> <kiskis-start-command> tmp.asc

$> rm -i tmp*
