Keylength is an stays the most important countermeasure against all the crypto - hacking the NSA and the Chinese have in their secret labs nowadays. I'm up to 8kb long keys since last year.

So have a nice next 20 years NSA and China should you ever put your fingers on one of my external hard-drives.

I never was a real fan of asymmetric crypto anyways and elliptic curves are often hacked beforehand so no trust from me into that too.
