[ale] split with encryption?

[Greg Freemyer]

All,

We often run a script that does something like:

dd if=/dev/sda | split

It would be really nice if could end up with encrypted files.

My ultimate goal is to create a boot CD that would have only the
public key on it that would allow the script to be run.

So it would be

dd if=/dev/sda | split --encrypt --public-key=key

I want the individual segment files could be decryptable individually,
so this is NOT useable:

   dd if=/dev/sda | gpg-like-tool | split

So does anyone know a split and encrypt tool pre-existing?

Thanks
Greg
