There's a new biggest known RSA modulus.
It is (in hexadecimal notation):

FF...(total of 9289166 F's)...FFDFF...(total of 1488985
F's)...FF800...(total of 9289165 0's)...001

It is guaranteed to be the product of two different large primes,

Are the primes actually known, or just "guaranteed to exist"?

and it has more than 80 million bits. Impressive security...

In what sense is this "impressive security"?

I have to agree that it is impressive, in the same way that having a nickname "Tripod" is impressive. Doesn't actually mean much in terms of reality neither is all that useful, or realistic for actual use. Joe
