PHP HMAC SHA256

$s = hash_hmac('sha256', 'Message', 'secret', true); echo base64_encode($s);

Java HMAC SHA256

import javax.crypto.Mac; import javax.crypto.spec.SecretKeySpec; import org.apache.commons.codec.binary.Base64; public class ApiSecurityExample { public static void main(String[] args) { try { String secret = "secret"; String message = "Message"; Mac sha256_HMAC = Mac.getInstance("HmacSHA256"); SecretKeySpec secret_key = new SecretKeySpec(secret.getBytes(), "HmacSHA256"); sha256_HMAC.init(secret_key); String hash = Base64.encodeBase64String(sha256_HMAC.doFinal(message.getBytes())); System.out.println(hash); } catch (Exception e){ System.out.println("Error"); } } }

Groovy HMAC SHA256

C# HMAC SHA256

using System.Security.Cryptography; namespace Test { public class MyHmac { private string CreateToken(string message, string secret) { secret = secret ?? ""; var encoding = new System.Text.ASCIIEncoding(); byte[] keyByte = encoding.GetBytes(secret); byte[] messageBytes = encoding.GetBytes(message); using (var hmacsha256 = new HMACSHA256(keyByte)) { byte[] hashmessage = hmacsha256.ComputeHash(messageBytes); return Convert.ToBase64String(hashmessage); } } } }

Objective C and Cocoa HMAC SHA256

Go programming language - Golang HMAC SHA256

package main import ( "crypto/hmac" "crypto/sha256" "encoding/base64" "fmt" ) func ComputeHmac256(message string, secret string) string { key := []byte(secret) h := hmac.New(sha256.New, key) h.Write([]byte(message)) return base64.StdEncoding.EncodeToString(h.Sum(nil)) } func main() { fmt.Println(ComputeHmac256("Message", "secret")) }

Ruby HMAC SHA256

require 'openssl' require "base64" hash = OpenSSL::HMAC.digest('sha256', "secret", "Message") puts Base64.encode64(hash)

Python (2.7) HMAC SHA256

import hashlib import hmac import base64 message = bytes("Message").encode('utf-8') secret = bytes("secret").encode('utf-8') signature = base64.b64encode(hmac.new(secret, message, digestmod=hashlib.sha256).digest()) print(signature)

Perl HMAC SHA256

use Digest::SHA qw(hmac_sha256_base64); $digest = hmac_sha256_base64("Message", "secret"); # digest is currently: qnR8UCqJggD55PohusaBNviGoOJ67HC6Btry4qXLVZc # Fix padding of Base64 digests while (length($digest) % 4) { $digest .= '='; } print $digest; # digest is now: qnR8UCqJggD55PohusaBNviGoOJ67HC6Btry4qXLVZc=
