Tell us how many years or centuries it will take. (Hint: Rivest and Schneier have done these

RSA-129 is 129 decimal digits, not 129 bits. This computes to about 425 bits, which is actually more difficult than the 384-bit Blacknet key.

I'm not having much luck on this example, am I? The RSA-129 I remembered correctly as being 129 decimal digits, but I spaced out on the 384-bit key and mislabelled it as "RSA-384." It'll be _many_ years before a 384-decimal-digit number is factored, I suspect. Let alone a 600-digit modulus, with or without the mysterious "transphaser" technology mentioned by Anitro. --Tim May Views here are not the views of my Internet Service Provider or Government. ---------:---------:---------:---------:---------:---------:---------:---- Timothy C.
