import fs from 'node:fs'
// input as an array of bits:
let output = sha3.hash([1,0,1,0,1,1,0,0], 'sha3-256')
// input as a file:
let file = fs.readFileSync('filename.txt')
let inputBits = sha3.byteArrToBitArr(file)
output = sha3.hash( inputBits, 'sha3-256')
// get the output as hex digits:
output = sha3.bitArrToByteArr(output.hash).map(byte => byte.toString(16))
// Supported variants: 'sha3-224', 'sha3-256', 'sha3-384', 'sha3-512',
