前言

在开发本库的过程中,发现了 PHP 的三个痛点,敬请各位务必要有所了解:

  1. PHP本身对其他进制转换为二进制,由于浮点数的长度特性,会造成数据丢失,这样就会造成运算结果的错误,需要自己重写;
  2. PHP的位运算符没法直接进行二进制变量的与或非运算,必须得自己重写;
  3. 碍于PHP本身的解释型、弱类型语言特点,运行速度没有C快,所以并不是最优选择。

但我们常说,看问题要有两面性。

尽管 PHP 本身有诸多问题,唱衰之声不断,但仍然发展到今天的生态规模, 很多时候,我们的实际性能需求并没有严格到要求我们去考量语言之间的速度差异,而重在功能的实现。

况且,上面提到的诸多痛点都已经被我封装在了这个库里, 性能的优化交给我来做,大家只要负责调用,来实现业务逻辑即可。

也希望大家来都来了,点个 WatchStar ,持续关注一下。在此拜谢!

特点

  1. 纯原生 PHP 代码,不额外依赖扩展项;
  2. OOP + Composer ,更优雅,安装更简单;
  3. 使用命名空间,防止变量名、方法名污染;
  4. 引入了 ComposerPSR-4 规范,进行类的自动加载;
  5. 使用 PSR-12 代码规范
  6. 代码注释完整, 可配合《 SM3密码杂凑算法 》食用, 方便进一步学习和研究本算法。

要求

  • 5.3 <= php < 7.2

7.2 之后版本理论通过,但因为 phpunit 的版本兼容性问题,没有单元测试支撑

1.x 版本之后只会作为低版本兼容,2.x 及之后版本会对 PHP 更高版本做

安装

本库优先支持 Composer 安装,但为了尊重使用习惯,也提供了直接下载压缩包的方式。 但不得不说,Composer 式的以组件、包为单位的项目管理方式更加现代化、方便和优雅。

一、源码解压(不推荐)

  1. 下载压缩包

    提供了 .zip.tar.gz 两种格式的压缩包, 压缩包已经过 Composer 包的优化

    下载地址:https://github.com/DongyunLee/SM3-PHP/releases/latest

  2. 解压到项目中的任意位置

    • Windows:

      使用 winrar/7zip/Bandizip 等工具解压

    • 类Unix:

      tar zxvf SM3-PHP.tar.gz
      # 或者
      unzip SM3-PHP.zip
    # 打包命令
    composer arch
    
    # 或 composer run-script arch

二、composer 安装(强烈推荐)

  1. 安装 composer

    详见 《如何安装 Composer

  2. 安装慢可更换中文镜像

    由于大量先前的镜像失效,所以目前(2019-11-25)推荐使用阿里云镜像

    其实配置中已经把镜像配置成了阿里云的镜像。 但有效范围毕竟只有这一个包。

    开发环境中还是建议进行下全局的配置。

    更换阿里云镜像方式详见拙笔 《向先行者致敬,迎接 Composer 的未来!

  3. composer require ch4o5/sm3-php

  4. composer install

  5. composer update

    下述 composer update 参数作为生产环境的优化,分析、调试和阅读代码无须使用

    参数简单说明:

    1. --prefer-dist:优先构建好的包,而不是源码
    2. --no-dev:不安装require-dev中定义的包,减小包的大小
    3. --no-plugins:不安装插件
    4. --with-dependencies:递归更新依赖的包
    5. --optimize-autoloader / -o:转换 PSR-0/4 autoload 到 classmap 可以获得更快的加载支持
    6. --classmap-authoritative: 推荐 使用后默认开启 -o,并对所有类加速

快速开始

在根目录中的 demo.php 中,进行了简单地调用示范:

<?php
/**
 * demo @ sm3-php
 *
 * Code BY ch4o5
 * 10月. 12th 2019
 * Powered by PhpStorm
 */

// 1. 引入项目中 Composer 的 autoload.php
require 'vendor/autoload.php';
// 2. 如果使用源码压缩包方式安装,则引入下面这句
// require '解压后的SM3-PHP目录/vendor/autoload.php';

// 直接调用提供的 sm3() 函数
$sm3 = sm3('abc');

// 使用它
echo $sm3;

你也可以在 examples/ 目录下找到更多的使用示例。

Effective Date The licenses granted in Section 2.1 with respect to any Contribution become effective for each Contribution on the date the Contributor first distributes such Contribution. 2.3. Limitations on Grant Scope The licenses granted in this Section 2 are the only rights granted under this License. No additional rights or licenses will be implied from the distribution or licensing of Covered Software under this License. Notwithstanding Section 2.1(b) above, no patent license is granted by a Contributor: (a) for any code that a Contributor has removed from Covered Software; or (b) for infringements caused by: (i) Your and any other third party's modifications of Covered Software, or (ii) the combination of its Contributions with other software (except as part of its Contributor Version); or (c) under Patent Claims infringed by Covered Software in the absence of its Contributions. This License does not grant any rights in the trademarks, service marks, or logos of any Contributor (except as may be necessary to comply with the notice requirements in Section 3.4). 2.4.

Representation Each Contributor represents that the Contributor believes its Contributions are its original creation(s) or it has sufficient rights to grant the rights to its Contributions conveyed by this License. 2.6. Fair Use This License is not intended to limit any rights You have under applicable copyright doctrines of fair use, fair dealing, or other equivalents. 2.7. Conditions Sections 3.1, 3.2, 3.3, and 3.4 are conditions of the licenses granted in Section 2.1. 3. Responsibilities ------------------- 3.1. Distribution of Source Form All distribution of Covered Software in Source Code Form, including any Modifications that You create or to which You contribute, must be under the terms of this License. You must inform recipients that the Source Code Form of the Covered Software is governed by the terms of this License, and how they can obtain a copy of this License. You may not attempt to alter or restrict the recipients' rights in the Source Code Form. 3.2. Distribution of Executable Form If You distribute Covered Software in Executable Form then: (a) such Covered Software must also be made available in Source Code Form, as described in Section 3.1, and You must inform recipients of the Executable Form how they can obtain a copy of such Source Code Form by reasonable means in a timely manner, at a charge no more than the cost of distribution to the recipient; and (b) You may distribute such Executable Form under the terms of this License, or sublicense it under different terms, provided that the license for the Executable Form does not attempt to limit or alter the recipients' rights in the Source Code Form under this License. 3.3. Distribution of a Larger Work You may create and distribute a Larger Work under terms of Your choice, provided that You also comply with the requirements of this License for the Covered Software. If the Larger Work is a combination of Covered Software with a work governed by one or more Secondary Licenses, and the Covered Software is not Incompatible With Secondary Licenses, this License permits You to additionally distribute such Covered Software under the terms of such Secondary License(s), so that the recipient of the Larger Work may, at their option, further distribute the Covered Software under the terms of either this License or such Secondary License(s). 3.4. Notices You may not remove or alter the substance of any license notices (including copyright notices, patent notices, disclaimers of warranty, or limitations of liability) contained within the Source Code Form of the Covered Software, except that You may alter any license notices to the extent required to remedy known factual inaccuracies. 3.5. Application of Additional Terms You may choose to offer, and to charge a fee for, warranty, support, indemnity or liability obligations to one or more recipients of Covered Software. However, You may do so only on Your own behalf, and not on behalf of any Contributor. You must make it absolutely clear that any such warranty, support, indemnity, or liability obligation is offered by You alone, and You hereby agree to indemnify every Contributor for any liability incurred by such Contributor as a result of warranty, support, indemnity or liability terms You offer. You may include additional disclaimers of warranty and limitations of liability specific to any jurisdiction. 4. Inability to Comply Due to Statute or Regulation --------------------------------------------------- If it is impossible for You to comply with any of the terms of this License with respect to some or all of the Covered Software due to statute, judicial order, or regulation then You must: (a) comply with the terms of this License to the maximum extent possible; and (b) describe the limitations and the code they affect. Such description must be placed in a text file included with all distributions of the Covered Software under this License. Except to the extent prohibited by statute or regulation, such description must be sufficiently detailed for a recipient of ordinary skill to be able to understand it. 5. Termination -------------- 5.1. The rights granted under this License will terminate automatically if You fail to comply with any of its terms. However, if You become compliant, then the rights granted under this License from a particular Contributor are reinstated (a) provisionally, unless and until such Contributor explicitly and finally terminates Your grants, and (b) on an ongoing basis, if such Contributor fails to notify You of the non-compliance by some reasonable means prior to 60 days after You have come back into compliance. Moreover, Your grants from a particular Contributor are reinstated on an ongoing basis if such Contributor notifies You of the non-compliance by some reasonable means, this is the first time You have received notice of non-compliance with this License from such Contributor, and You become compliant prior to 30 days after Your receipt of the notice. 5.2. If You initiate litigation against any entity by asserting a patent infringement claim (excluding declaratory judgment actions, counter-claims, and cross-claims) alleging that a Contributor Version directly or indirectly infringes any patent, then the rights granted to You by any and all Contributors for the Covered Software under Section 2.1 of this License shall terminate. 5.3. In the event of termination under Sections 5.1 or 5.2 above, all end user license agreements (excluding distributors and resellers) which have been validly granted by You or Your distributors under this License prior to termination shall survive termination. ************************************************************************ * * * 6.

Effect of New Versions You may distribute the Covered Software under the terms of the version of the License under which You originally received the Covered Software, or under the terms of any subsequent version published by the license steward. 10.3. Modified Versions If you create software not governed by this License, and you want to create a new license for such software, you may create and use a modified version of this License if you rename the license and remove any references to the name of the license steward (except to note that such modified license differs from this License). 10.4. Distributing Source Code Form that is Incompatible With Secondary Licenses If You choose to distribute Source Code Form that is Incompatible With Secondary Licenses under the terms of this version of the License, the notice described in Exhibit B of this License must be attached. Exhibit A - Source Code Form License Notice ------------------------------------------- This Source Code Form is subject to the terms of the Mozilla Public License, v. 2.0. If a copy of the MPL was not distributed with this file, You can obtain one at http://mozilla.org/MPL/2.0/. If it is not possible or desirable to put the notice in a particular file, then You may include the notice in a location (such as a LICENSE file in a relevant directory) where a recipient would be likely to look for such a notice.
