Er... As far as I knew, don't OpenPGP use RSA by default ?
Well...
a) OpenPGP uses symmetric ciphers to encrypt the actual data packets and the asymmetric algo is "just" used to encrypt the session-key-packet which holds the key used with the symmetric cipher.

b) The OpenPGP standard doesn't mandate default algos (just some subsets that implementations must support), and RSA is e.g. just the choice of GnuPG (and perhaps also others).

Thank you alot for your answer. I would appreciate very much getting your
script, to understand how you do things.
See the attachment, which is provided "as is".
Not that this is really made for the keyscripts framework provided with Debian (and stealing distros like *buntu), but of course you can modify them to work with anything you need. Also not, if you use them with Debian: The maintainer didn't accept to include them because... well I never really understood just a single point why,... but if he changes other cryptsetup scripts, mine might not longer work without being updated, too.


Cheers,
Chris.
