Quick answer:

o Download ftp://ftp.gnupg.dk/pub/contrib-dk/idea.c

o Compile:

        gcc -Wall -O2 -shared -fPIC -o idea idea.c

o Copy "idea" into your extensions dir, e.g <.../lib/gnupg>

o Add to ~/.gnupg/options:

	load-extension idea

You can now decrypt files you may have previously encrypted with "pgp -c".

cheers,
Calum.
