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

function hashData (bytes32 data) public pure returns (bytes32) {
      bytes32 hash =  keccak256(data);
      return hash;

hope this helps
