Comment Re:Who generates 512-bit RSA keys these days? (Score 1) 80

>RSA for example needs two prime numbers as a keypair, so while the key length might be 512 bit, there are actually not that many from those 2^512 numbers to choose from. Also, certain key values are prone to attacks.

How many is not that many? Bruce Schneier in Cryptography Engineering calculates that 1 in 1386 numbers in the 2^2000 bit range is prime. In the 2^512 range primes are even more frequent, according to prime counting estimates.

It would get very tiresome for everyone to have to explain from axioms and first principles every opinion they held, even if they did reflect upon and study them.
Alternately, do you think people who agree with you on whatever subject have also been "culturally informed" that way?

I am, of course, not talking about capitalism, communism, chalk, or cottonballs, but wearing socks with sandals.
