We updated the VHDL package of Keccak to be compliant with its new padding rule. In fact, the VHDL code itself has not changed since version 2.0, as the underlying permutation was not modified. But we updated the testing program in C to be in line with the new padding rule and to support input messages of any bit length.
The new package can be downloaded here.
