This gives you two options. One, use brute force to break

I think you may mean something slightly differently; given any large
prime p, I can factor it completely extremely quickly:

p = 1 * p

There are no other factors; this *is* the prime factorization. :) Bill
Gates made the same mistake in his book _The Road Ahead_. Factoring
large primes is trivial; the prime factorization of large numbers is
hard, and I guess that's what you meant.

The whole security of encryption rests on the belief that prime factorization isn't possible in a reasonable time, and it may well have been solved.

Need we tell you again?

READ THE DEFINITION OF A PRIME NUMBER. Here's a site with a good definition:


A prime number, BY DEFINITION, cannot be factored. Factoring products of large primes - for example,


- is believed to be a Hard problem, and that's what RSA is based on.

(The factorization is at the bottom of this message.)

Why would any government admit that it had cracked RSA security and its derivates?

It wouldn't. Partially because:

 - Governments use RSA too.

 - Businesses use RSA as well.

Declaring RSA broken would kill e-commerce overnight.

I realise that we are getting into the realms of conspiracy theories now, however history shows that the UK did not wish it to be made public during the war that it had cracked the Enigma code. Why should it be any different now?

Because we aren't at war with Rivest, Shamir, and Adleman?

A prime is defined as being divisible by itself and 1 only, so for the purpose of the definition, 1 is not a factor.

Okay, so you do remember your elementary school math. So explain how "prime factorization" is possible, then.

Even if Embryonic Stem Cell Research yielded medical treatments, how could enough eggs be obtained to make them viable? We can't even get enough organs for transplant donation.

Easily. Eggs are much easier to obtain than organs.

Since you scrolled down to see it: Mathematica factors
