Hi,

just started a fork to add VIA padlock harware accelaration for the sha256 functionality.  Find the git tree at:

  [removed dead link]

This is a very clean patch currently, only adding a few lines to cryptopp/sha.cpp .  Should be much cleaner (and more generic) then the code posted before here:

  http://bitcointalk.org/index.php?topic=355.0

Note that the code by Sgtstein even had a possible corruption bug when IRQs interrupted the crypto engine.

Still verifying whether it works.  Would be grateful for comments.

cheers,

David

the sha256 instruction will automaticlly restart after an interrupt much like any rep instruction. I am quite sure it is correct as is
