fyi/fwiw: Buried in the abstract for http://eprint.iacr.org/2017/566 is 

"A side product of our implementation effort is a new optimized circuit 
for SHA256 with less than a quarter than the number of AND gates of the 
best previously publicly available one. Our new SHA256 circuit may be of 
independent use for circuit-based MPC and FHE protocols that require 
SHA256 circuits."

[ i take MPC and FHE to be "multi-party computation" and "Fully 
homomorphic encryption", fwiw ]
