Soln to the previous prob

this is pretty easy...n practically it was in use till very recently by banks...


wat u do... lock it in a box using ur own lock n key...n then send it across to the destination..kepin the key wid u..at the destination the intended receiver puts anothr lock on it and sends it back kepin the key wid himself..

wen it comes back the first u open the first lock..so the 2nd one is stil in place..n send it across..

at the receivin end...its opened by their own key..

how you achieve it practically depends on particular needs...bt its definitely simple n practical...


now why am i talkin about it ...jus think if you cud use such a thing in emails...fool proof security...
