def keccak256( input )
## todo/fix: check if input is binary string 
##    (convert to bytes - why? why not?)
##    should really always use hex_to_bin !!! 
##    and convert the result in the end only - why? why not??

  str = Types::String.new( input )

  ## fix: convert hexdigest to binary
  '0x' + Digest::KeccakLite.hexdigest( str.as_data, 256  )
end
