<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">screw plus是一个开源的php扩展，<span style="color: black;">功效</span>是对php文件进行加密，网络上<span style="color: black;">供给</span>php加密的服务<span style="color: black;">非常多</span>，但大多都只是混淆级别的加密，被人拿到加密文件问只要有足够耐心就能破解，与之<span style="color: black;">区别</span>的是，screw plus采用扩展来加解密，<span style="color: black;">况且</span>是<span style="color: black;">全世界</span>金融业流行的高强度AES256加密，除非破解了服务器，否则黑客拿到了加密文件<span style="color: black;">亦</span>只是一堆乱码。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">同一个加密级别的有ioncube和官方的zend guard，但这两款都是收费的，一年至<span style="color: black;">少许</span>千元的<span style="color: black;">花费</span>并不值得普通<span style="color: black;">研发</span>者去尝试，而<span style="color: black;">运用</span>screw plus，你不<span style="color: black;">必须</span>多花一分钱。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">下面以LNMP一键安装环境为例演示下screw plus的配置</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">首要</span>克隆一份代码到服务器</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">git clone <a style="color: black;"><span style="color: black;">https://</span><span style="color: black;">git.oschina.net/splot/p</span><span style="color: black;">hp-screw-plus.git</span></a></p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">进入项目目录，<span style="color: black;">而后</span>执行php的phpize文件，phpize是官方<span style="color: black;">供给</span>的可执行文件用于动态生成扩展<span style="color: black;">研发</span>环境，<span style="color: black;">通常</span>在php的bin目录下<span style="color: black;">能够</span>找到。lnmp的phpize在/usr/local/php/bin/phpize</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">/usr/local/php/bin/phpize</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Configuring for:</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">PHP Api Version: 20100412</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Zend Module Api No: 20100525</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Zend Extension Api No: 220100525</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">执行成功后<span style="color: black;">能够</span>看到当前的php api版本，扩展api版本等。下一步就<span style="color: black;">能够</span><span style="color: black;">起始</span>配置了。配置命令为 ./configure --with-php-config=, <span style="color: black;">通常</span><span style="color: black;">亦</span>在php的bin目录下，写绝对路径就<span style="color: black;">能够</span>了。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">./configure --with-php-config=/usr/local/php/bin/php-config</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">倘若</span>没报错，说明配置成功了，<span style="color: black;">能够</span><span style="color: black;">起始</span>下一步编译了。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">编译之前，<span style="color: black;">咱们</span><span style="color: black;">能够</span>修改加密的key，打开php_screw_plus.h<span style="color: black;">能够</span>看到开头<span style="color: black;">便是</span> #define CAKEY "..." ,把里面的值改为一个足够<span style="color: black;">繁杂</span>的key，最好16位以上，<span style="color: black;">例如</span>：9mqss6q7WsBpTMOZ</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">vi php_screw_plus.h</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">修改完毕之后，直接<span style="color: black;">起始</span>编译，执行make命令，<span style="color: black;">倘若</span>最后<span style="color: black;">表示</span>Build complete.说明编译成功，扩展在modules里面，<span style="color: black;">倘若</span>报错请<span style="color: black;">按照</span>提示进行修复，<span style="color: black;">而后</span>make clean之后重新编译。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">make</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">...</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">Build complete.</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">上面<span style="color: black;">咱们</span>编译的是解密程序，而加密程序<span style="color: black;">亦</span><span style="color: black;">必须</span><span style="color: black;">咱们</span>手动编译一下，进入tools目录执行make命令<span style="color: black;">就可</span>。<span style="color: black;">倘若</span><span style="color: black;">无</span>报错，则扩展就<span style="color: black;">所有</span>编译完<span style="color: black;">成为了</span>。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">cd tools/ && make</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">而后</span><span style="color: black;">必须</span>把扩展的路径加入到php.ini中，你<span style="color: black;">能够</span>把modules/php_screw_plus.so复制到php扩展目录<span style="color: black;">亦</span><span style="color: black;">能够</span>直接在ini中加入绝对路径，我<span style="color: black;">通常</span>倾向于绝对路径<span style="color: black;">这般</span>修改编译了扩展<span style="color: black;">亦</span>不<span style="color: black;">必须</span>重新复制过去。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">vi php/etc/php.ini</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">加入绝对路径例如</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">extension=/home/php_screw_plus-1.0/modules/php_screw_plus.so</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">而后</span>重启php服务 <span style="color: black;">此时</span><span style="color: black;">能够</span>放个php文件输出phpinfo信息，<span style="color: black;">倘若</span>看到以下提示说明扩展生效了。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">下面还有最后一步，加密程序。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在扩展的tools目录，执行./screw [路径]，[路径]<span style="color: black;">能够</span>是单个文件<span style="color: black;">亦</span><span style="color: black;">能够</span>是文件夹，<span style="color: black;">而后</span>就<span style="color: black;">能够</span>实现加密了。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">加密完成后查看源码，<span style="color: black;">能够</span><span style="color: black;">发掘</span>除了开头的几个英文字符外，其余的都<span style="color: black;">成为了</span>乱码。</p>
<p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">然则</span>打开网站，php运行正常，<span style="color: black;">倘若</span><span style="color: black;">无</span>加密<span style="color: black;">同样</span>。经过测试，解密速度大约为100M每秒，对php<span style="color: black;">自己</span>的性能损失非常小，<span style="color: black;">通常</span>不到20毫</p>
