sha3Raw

The sha3Raw function is a utility method provided by the web3.utils module that calculates the Keccak-256 hash of the input data and returns the hash value as a string. Unlike the sha3 function, sha3Raw will always return a string value, even if the input data is an empty string or a buffer of zero length.

The function takes a single parameter:

• data, which is the input data to be hashed. The data parameter can be a string or a buffer of bytes.

The sha3Raw function returns a string representation of the Keccak-256 hash of the input data. If the input data is an empty string or a buffer of zero length, the function returns a string value that is not undefined.

Here's an example of how the sha3Raw function can be used:

In this example, the sha3Raw function is called with a string data and an empty string emptyData. The function returns a string representation of the Keccak-256 hash of the input data for both calls, with the hash value being different for each input.
