I beg to differ.
dd ... | gpg -c > /tmp/output works
Use gpg -d /tmp/output to decrypt the file.
or
dd ... | openssl aes-256-cbc -salt -out /tmp/output
Use openssl aes-256-cbc -d -in /tmp/output to decrypt the file.

There are multiple options, first use the persistent bootoption, see
http://wiki.grml.org/doku.php?id=persistency
OTOH you can place debs in a specific folder/partition and they will be
installed automatically. See
http://grml.org/config/grml-autoconfig.1.html for the list of
bootoptions.
