Use HMAC or RSA to sign data for Laravel and lumen;

Install

For Laravel < 5.5, please use the tag 0.2.10

laravel

composer require kangyasin/signature

lumen

• bootstrap/app.php

    $app->register(Kangyasin\Signature\Facade\Signature::class);
  

config

• you can use these in your ENV

    // default driver
    SIGNATURE_DRIVER
  
    // hmac algo and key
    SIGNATURE_HMAC_ALGO (default sha256)
    SIGNATURE_HMAC_KEY (default null)
  
    // rsa algo, public_key, private_key
    SIGNATURE_RSA_ALGO (default sha256)
    SIGNATURE_RSA_PUBLIC_KEY
    SIGNATURE_RSA_PRIVATE_KEY
  

• if you want to use config

    laravel
    php artisan vendor:publish
  
    lumen
    copy vendor/kangyasin/signature/src/config/config.php config/signature.php
  

Usage

sign

$signature = Signature::sign('foobar');

$signature = Signature::setKey('foobar')->sign(['foo'=>'bar']);

$signature = Signature::signer('hmac')
    ->setAlgo('sha256')
    ->setKey('foobar')
    ->sign(['foo'=>'bar']);

$signature = Signature::signer('rsa')
    ->setPrivateKey('./private.pem')
    ->sign(['foo'=>'bar']);

verify

// true or false

Signature::verify($signature, 'foobar');

Signature::setKey('foobar')->verify($signature, ['foo'=>'bar']);

Signature::signer('hmac')
    ->setAlgo('sha256')
    ->setKey('foobar')
    ->verify($sign, ['foo'=>'bar']);

Signature::signer('rsa')
    ->setPublicKey('./public.pem')
    ->verify($signature, ['foo'=>'bar']);

Sign Steps

• convert array data

    // origin
    $data = [
        'z' => 1,
        'a' => [
            'c' => 'c',
            'b' => 'b',
            'a' => [
                'b' => 'b',
                'a' => 'a'
            ]
        ],
    ];
  
    // ksort and convert to string
    $data = [
        'a' => [
            'a' => [
                'a' => 'a'
                'b' => 'b',
            ]
            'b' => 'b',
            'c' => 'c',
        ],
        'z' => '1',
    ];
  
    // json_encode
    {"a":{"a":{"a":"a","b":"b"},"b":"b","c":"c"},"z":"1"}
  

• sign string。

    hmac  => hmac($algo, $convertData, $key);
    // outputs lowercase hexits
  
    rsa => base64_encode(openssl_sign_string);
