   Shamir cracked the knapsack encryption scheme, not the RSA.  I don't
remember the details offhand (there was a talk at Crypto 82 about it,
but I don't have the extended abstract at hand) but if you iterated the
encryption method, Shamir's attack would fail.  Adelman claims to have
gotten around this; again I don't know details.
   As far as I know, RSA is still secure if you pick your numbers right.
