Saw an interesting article from Gmail on their inbound email statistics. Over 91% is authenticated with either DKIM or SPF.
What percentage of that is using 512-bit keys?
They didn't say. (And the threat model for spam protection probably doesn't include spammers cracking RSA keys, so 512-bit would be perfectly adequate, but I'd hope people were using 1024.)
