Returns Keccak-256 (not the standardized SHA3-256) of the given data.

Note: web3_sha3 takes in a hexadecimal number, not a direct string. So, if you wanted to convert "hello world" to its Keccak-256 hash you would need to input the hex number for "hello world", which is "0x68656c6c6f20776f726c64".

PARAMETERS

Data - (required) The data in hex form to convert into a SHA3 hash.
