Hmac-SHA1 in many language

 

Hmac-SHA1

 

1. In C#:

using System;

using System.Security.Cryptography;

using System.Text;

private static string HmacSHA1(string input, string secretKey)

        {

            var enc = Encoding.UTF8;

            HMACSHA1 hmac = new HMACSHA1(enc.GetBytes(secretKey));

            byte[] hash = hmac.ComputeHash(enc.GetBytes(input));

            return Convert.ToBase64String(hash);

        }

 

 

2. In Java:

import java.security.SignatureException;

import java.util.Base64;

 

import javax.crypto.Mac;

import javax.crypto.spec.SecretKeySpec; 

 

public static String hmacSHA1(String value, String secretKey) throws java.security.SignatureException {

            String result;

            try {

String HMAC_SHA1_ALGORITHM = "HmacSHA1";

                  SecretKeySpec signingKey = new SecretKeySpec(secretKey.getBytes(), HMAC_SHA1_ALGORITHM);

                  Mac mac = Mac.getInstance(HMAC_SHA1_ALGORITHM);

                  mac.init(signingKey);

                  byte[] hash = mac.doFinal(value.getBytes());

                  result = new String(Base64.getEncoder().encode(hash));

            } catch (Exception e) {

                  throw new SignatureException("Failed to generate HMAC : " + e.getMessage());

            }

            return result;

      }

 

 

3. In Python:

import base64

import hashlib

import hmac

 

def _hmac_sha1(input_str,key):
    inputRaw = input_str.encode("utf-8")
    keyRaw = key.encode('utf-8')
    hashed = hmac.new(keyRaw, inputRaw, hashlib.sha1)
    return base64.encodebytes(hashed.digest()).decode('utf-8')

 

 

 

4. In dart

import 'dart:convert';

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

static String hmacSHA1(String input, String secretKey) {

  var bytes = utf8.encode(input);

  var key = utf8.encode(secretKey);



  crypto.Hmac hmacSha1 = new crypto.Hmac(crypto.sha1, key); 

  crypto.Digest digest = hmacSha1.convert(bytes);



  return base64.encode(digest.bytes);

}
