  2. Security: The SHA3-256 Hash Generator uses local computing, meaning your input string is not sent over the internet. This makes it a secure option for generating SHA3-256 hashes.
  3. Efficiency: The SHA3-256 Hash Generator is a fast and efficient way to generate SHA3-256 hashes. You can generate the hash for any input string in just a few seconds.

Example Code

Here are examples of how to generate SHA3-256 hashes using the SHA3-256 Hash Generator in Python, Java, JavaScript, Golang, Ruby, and PHP:


import hashlib

input_string = "Free Online Tools"

hash_object = hashlib.sha3_256(input_string.encode())
hex_dig = hash_object.hexdigest()



import java.nio.charset.StandardCharsets;

public class SHA3Generator {
    public static void main(String[] args) throws NoSuchAlgorithmException {
        String inputString = "Free Online Tools";

        MessageDigest digest = MessageDigest.getInstance("SHA3-256");
        byte[] hash = digest.digest(inputString.getBytes(StandardCharsets.UTF_8));

        StringBuffer hexString = new StringBuffer();
        for (int i = 0; i < hash.length; i++) {
            String hex = Integer.toHexString(0xff & hash[i]);
            if(hex.length() == 1) hexString.append('0');



const inputString = "Free Online Tools";

const digest = new TextEncoder().encode(inputString);
const hash = crypto.subtle.digest("SHA-3-256", digest);

hash.then((result) => {
  console.log(new Uint8Array(result).toString());


package main

import (

func main() {
    inputString := "Free Online Tools"

    hash := sha3.Sum256([]byte(inputString))



require 'digest'

input_string = "Free Online Tools"

hash = Digest::SHA3.hexdigest(input_string, 256)

puts hash


$inputString = "Free Online Tools";

$hash = hash("sha3-256", $inputString);

echo $hash;
