If you are looking for an online SHA-256 hash generator that is free and easy to use, this tool is perfect for you. With no dependencies and a simple interface, this tool allows you to obtain the SHA-256 hash of any string in seconds, ensuring data security and local computing. In this manual, we will introduce the tool's features, guide you on how to use it, and provide sample code for popular programming languages such as Python, Java, JavaScript, node js, and PHP.

Features

• Online and free, no system and software dependencies
• Can clear input, copy output, and provide sample inputs
• Data security and local computing

Tool Introduction

The tool provides a simple interface where you can input the text string that you want to hash. Once you have input the string, simply click the "Generate" button, and the tool will generate the SHA-256 hash of the input string. You can then copy the generated hash by clicking the "Copy" button or clear the input by clicking the "Clear" button.

How to use

1. Go to the SHA-256 hash tool website
2. Input the string that you want to hash in the input field
3. Click the "Generate" button
4. Copy the generated SHA-256 hash by clicking the "Copy" button or clear the input by clicking the "Clear" button

Example Codes

Python

import hashlib

input_string = "IToolkit"
hashed_string = hashlib.sha256(input_string.encode()).hexdigest()
print(hashed_string)

Java

import java.nio.charset.StandardCharsets;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;

public class SHA256HashGenerator {
    public static void main(String[] args) throws NoSuchAlgorithmException {
        String inputString = "IToolkit";
        MessageDigest digest = MessageDigest.getInstance("SHA-256");
        byte[] encodedHash = digest.digest(inputString.getBytes(StandardCharsets.UTF_8));
        StringBuffer hexString = new StringBuffer();
        for (byte hash : encodedHash) {
            String hex = Integer.toHexString(0xff & hash);
            if (hex.length() == 1) hexString.append('0');
            hexString.append(hex);
        }
        System.out.println(hexString.toString());
    }
}

JavaScript

const sha256 = require("js-sha256");

let inputString = "IToolkit";
let hashedString = sha256(inputString);
console.log(hashedString);

Node.js

const crypto = require("crypto");

let inputString = "IToolkit";
let hashedString = crypto
  .createHash("sha256")
  .update(inputString)
  .digest("hex");
console.log(hashedString);

PHP

$inputString = "IToolkit";
$hashedString = hash('sha256', $inputString);
echo $hashedString;
