I have this solidity function below. It is supposed to return the hash of a given data, but instead I get this: 0x

 function hashData (bytes32 data) public constant returns (bytes32) {
      var hash =  keccak256(data);
      return hash;
  }

  • Works for me as well, have you put the data in like so "data" and also instead of using var hash try using bytes32 hash

      bytes32 hash =  keccak256(data);
