RE: Rijndael selected as AES
In the larger MODP DH groups that Tero had posted, the most/least
significant 64 bits are set in the prime. It's been suggested to me that
having the most/least significant 128 bits set may allow certain
optimizations on CPUs with a larger word size.

Subject: Re: Rijndael selected as AES
Has it occurred to anyone the silliness of adding AES to IPsec/IKE without
adding larger primes to IKE? There was a discussion in March on this list
with regards to larger primes, but it died out around the time someone
would need to have written a draft. I believe Tero did post the larger DH
primes to the list. Any volunteers to write that up?
