What is the fastest public SHA256^2 code for x86?

2

I am asking about the double SHA256 hashing function - the one that bitcoin uses.

Which publicly available implementation is the fastest one out there?

It can be in assembler, as long as it is for x86, also 64 bit.

I suspect, that since SHA256 has no real weaknesses, you can't do 2x SHA256 faster than twice the time of one SHA256... – Janus Troelsen – 2014-03-11T11:13:03.917
