Just out of curiosity, can anyone with access to a gigabit network run some
tests and tell us the difference between using several different keys? Like
1024, 1280, 2048, 4096.
I'm curious if a bigger key really slows down the operation as Bruce Schneier
implies ("Doubling the key size roughly corresponds to a six-times speed slowdown
in software").
