Whirlpool is not specified by OpenPGP and thus not supported by gpg.

FWIW, Libgcrypt has support for Whirlpool and thus can be used by other
applications (e.g. S/MIME as supported by gpgsm)

Let us know when you are done with the patch.  I'd be interested in
trying it out -- that would make one person who could verify your
signature!

The addition of Whirlpool would require the effective 'patching' of 11
Files.  I am fooling with it in My spare time but haven't completed it
as yet.

I haven't devoted much time to this as there would be very few instances
where it would be practical to implement. What would be accomplished by
using a Hash that would prevent anyone from verifying My Sig?

Not that I know of.  Note that Whirlpool is not specified for OpenPGP,
so that is a major barrier.

There is a project to add Whirlpool to OpenPGP going on at the moment
(also the Camellia cipher, by the way).  When that happens, Whirlpool
makes more sense than it does now.
