Use the keccak-256 hash algorithm to calculate the hash value of a given string.

Call:

Web3.sha3 (string, options)

Parameters:

String: String-the string passed in that needs to be hashed using the Keccak-256 SHA3 algorithm.

Options: Object-optional settings. If you are parsing a hexadecimal string in hex format. You need to set encoding to hex. Because 0x is ignored by default in JS.
