It doesn't have to be because Ly> there are hidden flaws in DES. But not all govt material requires (or is given) protection that should last for 50 years. While some information may be of crucial importance for several days (say) it will become worthless shortly thereafter. Isn't the point that breaking a cypher - be it DES or any other - would endanger vital short term information too. Information should be classified by its sensitivity alone (though automatic declassification should be possible once it has passed its 'sell by' date. Therefore, no highly classified material ought to be entrusted to any system where there is doubt as to its medium term security. It would seem that the US and other major governments take that view. In my opinion, commercial users bearing appreciable levels of threat to their information security (e.g. hi-tech R&D, financial institutions, pharmecutical and bio-engineering companies) would be well advised to take a similar view. ___ Blue Wave/QWKv2.11
