Thanks to the folks who answered my first question about the relative strengths of RSA and IDEA. Okay, 1024-bit RSA keys are easier to brute-force than 128-bit IDEA keys. Currently. We think. That's what I should have stressed in the first place. Aren't people more sure of what they think about the toughness of RSA, than they are of what they think about IDEA? (Less important question: how many RSA keys are there, as a function of size? I'm getting ln(2^(number of bits))^2, which can't be right.) -fnerd quote me - - cryptocosmology- sufficiently advanced communication is indistinguishable from noise - god is in the least significant bits -----BEGIN PGP SIGNATURE----- Version: 2.3a aKxB8nktcBAeQHabQP/d7yhWgpGZBIoIqII8cY9nG55HYHgvt3niQCVAgUBLMs3K ui6XaCZmKH68fOWYYySKAzPkXyfYKnOlzsIjp2tPEot1Q5A3/n54PBKrUDN9tHVz 3Ch466q9EKUuDulTU6OLsilzmRvQJn0EJhzd4pht6hSnC1R3seYNhUYhoJViCcCG sRjLQs4iVVM= =9wqs -----END PGP SIGNATURE-----
