I think I should implement it when it is in the draft.  Due to the
patent problems there is no IDEA support.  The symmetric encryption
was the first piece I wrote and I replaced IDEA by BLowfish - even
before I know about OpenPGP and the new packets.  I guess that is
the reason that there is no support for this.  I will test whether
IDEA is available and then use it instead of the default cipher -
using MD5 should be no problem at all.
