Summary: blog posting claims most of the Tor network is still running
older software that uses 1024 bit Diffie-Hellman.

I'm not sure how cheap it actually would be to routinely crack DH key
exchanges, but it does seem like it would be valuable for
most Tor nodes to be running newer software anyway.
