I am using keccak hashing algorithm for converting documents to hashes, the algorithm is producing hashes like: **8185f41244d1a00110cff37b60732228623a82e7da905cac00777029887816ff**

I want to store this hash in a smart contract in bytes32 rather than string (bytes32 consumes less gas then string) but I am getting error message as: Given parameter is not bytes


Given parameter is not bytes

You have to add 0x at starting of your hash 8185f41244d1a00110cff37b60732228623a82e7da905cac00777029887816ff like this "0x8185f41244d1a00110cff37b60732228623a82e7da905cac00777029887816ff".
