If I ignore the "trust" bit in results I'm still getting just: EXP-EDH-RSA-DES-CBC-SHA 41804 6.2565 From 668168 sample. But then there is something which matches rather well the percentage: EDH-RSA-DES-CBC-SHA 75939 11.3653 (note the lack of "EXP-") -- Regards, Hubert Kario Quality Engineer, QE BaseOS Security team Web: www.cz.redhat.com Red Hat Czech s.r.o., Purkyňova 99/71, 612 45, Brno, Czech Republic
