HMAC Gost-crypto Generator Online

HMAC Gost-crypto Generator Online is an online tool from Website Codezi.pro that helps programmers to generate a cryptographic hash from the input of a string and a secret key. This tool uses the “gost-crypto” algorithm to generate the HMAC Gost-crypto hash. It is a useful tool for testing, comparing results to the string that the programmer has before.

HMAC Gost-crypto is an abbreviation of “Hash-based Message Authentication Code”, which is a type of message authentication code algorithm. The HMAC Gost-crypto Generator Online creates a secure and encrypted hash from a given string and secret key. The generated hash is used to verify the authenticity of the data.

The input of the HMAC Gost-crypto Generator Online is a string and secret key. The string is the data that needs to be verified, while the secret key is a secret code that the user provides. The secret key is used to generate the HMAC Gost-crypto hash which is then compared to the original string.

The HMAC Gost-crypto Generator Online is a useful tool for developers who need to generate and verify cryptographic hashes. The secure and encrypted hash generated by the tool can be used to ensure the integrity of the data. It is recommended that the secret key should be kept secure and not be shared with anyone.

HMAC Gost-crypto Generator Online is an easy to use tool and can be used to quickly generate and verify cryptographic hashes. It is a valuable tool for developers who need to verify the authenticity of data. With its help, the user can easily generate a secure and encrypted hash from a given string and secret key.

Php HMAC Gost-crypto Example

<?php 

$key = "1234567890abcdef";
$message = "This is a test message";

$hmac = hash_hmac('gost-crypto', $message, $key);

echo "HMAC gost-crypto: {$hmac}";

?>

Nodejs HMAC Gost-crypto Example

const crypto = require('crypto');

const key = "1234567890abcdef";
const message = "This is a test message";

const hmac = crypto.createHmac('gost-crypto', key).update(message).digest('hex');

console.log(`HMAC gost-crypto: ${hmac}`);

Java HMAC Gost-crypto Example

import javax.crypto.Mac;
import javax.crypto.spec.SecretKeySpec;
import java.nio.charset.StandardCharsets;
import java.util.Base64;

public class HMACGost {

    public static void main(String[] args) throws Exception {
        String key = "1234567890abcdef";
        String message = "This is a test message";
        Mac sha256_HMAC = Mac.getInstance("GOST-CRYPTO");
        SecretKeySpec secret_key = new SecretKeySpec(key.getBytes(StandardCharsets.UTF_8), "GOST-CRYPTO");
        sha256_HMAC.init(secret_key);

        byte[] hmac = sha256_HMAC.doFinal(message.getBytes());
        String encodedHmac = Base64.getEncoder().encodeToString(hmac);
        System.out.println("HMAC gost-crypto: " + encodedHmac);
    }

}

Dart  Example

import 'dart:convert';
import 'package:crypto/crypto.dart';

void main() {
  final key = '1234567890abcdef';
  final message = 'This is a test message';
  final hmac = Hmac(GostCrypto(), utf8.encode(key)).convert(utf8.encode(message));
  print('HMAC gost-crypto: ${hmac.toString()}');
}

Python HMAC Gost-crypto Example

message = "This is a test message"

hmac = hmac.new(key.encode('utf-8'), message.encode('utf-8'), hashlib.gost_crypto).hexdigest()

print("HMAC gost-crypto: " + hmac)
