Examples in Programming Languages

Here are some examples of how to use the Keccak 256 Hash Tool in various programming languages:

Python

import hashlib

def keccak_256(string):
    hash = hashlib.sha3_256()
    hash.update(string.encode('utf-8'))
    return hash.hexdigest()

print(keccak_256('IToolkit')) # Output: 01fa8b547c0d475372831afd9b72aa7d0b6b9591da2e6a10222ccdbd67a84967

Java

import java.security.MessageDigest;

public class Keccak256 {
    public static String hash(String string) throws Exception {
        MessageDigest md = MessageDigest.getInstance("SHA3-256");
        md.update(string.getBytes("UTF-8"));
        byte[] digest = md.digest();
        return bytesToHex(digest);
    }

    private static final char[] HEX_ARRAY = "0123456789abcdef".toCharArray();
    public static String bytesToHex(byte[] bytes) {
        char[] hexChars = new char[bytes.length * 2];
        for (int i = 0; i < bytes.length; i++) {
            int v = bytes[i] & 0xFF;
            hexChars[i * 2] = HEX_ARRAY[v >>> 4];
            hexChars[i * 2 + 1] = HEX_ARRAY[v & 0x0F];
        }
        return new String(hexChars);
    }

    public static void main(String[] args) throws Exception {
        System.out.println(hash("IToolkit")); // Output: 01fa8b547c0d475372831afd9b72aa7d0b6b9591da2e6a10222ccdbd67a84967
    }
}

JavaScript

const crypto = require("crypto");

function keccak256(string) {
  return crypto.createHash("sha3-256").update(string).digest("hex");
}

console.log(keccak256("IToolkit")); // Output: 01fa8b547c0d475372831afd9b72aa7d0b6b9591da2e6a10222ccdbd67a84967

PHP

function keccak256($string) {
    return hash('sha3-256', $string);
}

echo keccak256('IToolkit'); // Output: 01fa8b547c0d475372831afd9b72aa7d0b6b9591da2e6a10222ccdbd67a84967
