======================

if you're paranoid about RSA, then there's no reason to go to ECC since 
the math behind it is still young and uncertain. while a 1024 bit RSA key 
~may~ not be secure for a long time, it's old age is due only to computing 
horsepower, not a "break" in the math behind it. as such, a larger RSA key 
buys time... and only time will tell if it buys "enough" time for a 
particular need.

gpg does support RSA-2048/SHA-256 (or even RSA-4096/SHA-512) which is what 
i've been using for a while now. i'll sign this email with 
RSA-2048/SHA-256 (my default on this key) just to show what it looks like. 
it's a big signature block, but not ridiculous and on a reasonably 
powerful computer it's hardly a noticeable delay to work with such keys.
