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...

Actually it's 2048, which I was comfortable with.  And don't forget the 16bit salt on that password ;)
