You don't think I considered it? Really? You think that I would go through the trouble of designing and implenting a standards based encrytion application without considering that it could be cracked? You are incorrect. I certainly considered it. I just know that when brute forcing AES256 becomes feasible, a scan of mynpssport will be the last thing on anyone mind.
Brute forcing AES256 will never be feasible. Factoring your RSA key will be -- soon too.
How does this differ from SSL, and why do you think I would have to be "live on the wire" to crack it? If your entire argument is "it can be cracked at some point" then you argue against *any* type of encrytion. Postulative statements in the obvious are a waste of people's time. T
You're using a 1024 bit key here which seems a bit gutsy ;-) Without better attacks, you basically have: Brute force AES 256 -> O(2^256) Bruce force your 20 char password -> roughly O(2^(20*7)) == O(2^140) Factor your 1024 bit public modulus -> roughly O(2^80) Since a 768 bit RSA key has already been factored I'd say you only have a few years before a moderately sized cluster could factor your public key. Of course, as I write this I realize I'm about to sign this message with a 1024 bit DSA key...
