创建加密解密类

直接上代码吧

<?php
/**
 * 加解密类

namespace App\Utils;

class Encrypt{

    protected static $instance = [];
    public $set = [];

    /*
     * 初始化加密类型
     * @param string $type
     * @param array $set
     * @return object
     */
    public static function init($type,$set){
        if (isset(self::$instance[static::class])) {
            return self::$instance[static::class];
        } else {
            return self::$instance[static::class] = new static($type,$set);
        }
    }

    /*
     * 初始化加密类型
     * @param string $type
     * @param array $set
     */
    public function __construct($type,$set){
        switch (strtolower($type)){
            case 'aes' :
                $this->set = $set;
                break;
            case 'uuid' :
                $this->set = $set;
                break;
            default :
                break;
        }
    }

    /*

     * (AES/CBC/PKCS5Padding或AES/CBC/PKCS7Padding)
     *
     * @param string $str 待加密/解密的恶字符串

     * @return string
     */
    public function aes($str,$type = 'enc'){
        $key = $this->set['key'];
        $iv = $this->set['iv'];
        switch (strtolower($type)){
            case 'dec' ://解密
                return openssl_decrypt(base64_decode($str), 'AES-128-CBC', $key, OPENSSL_RAW_DATA, $iv);
                break;
            default ://加密
                return base64_encode(openssl_encrypt($str, 'AES-128-CBC',$key, OPENSSL_RAW_DATA , $iv));
                break;
        }
    }

    /*

     */
    function uuid($uuid = null,$type = 'enc')
    {
        switch (strtolower($type)){
            case 'dec' ://解密
                $rez=Array();
                $u=explode("-",$uuid);
                if(is_array($u)&&count($u)==5) {
                    $rez=Array(
                        'time'=>hexdec($u[0]),
                        'micro'=>(hexdec($u[1])/65536),
                        'sid'=>substr($u[4],0,4),//前4位
                        'ip'=>long2ip(hexdec(substr($u[4],4))),//4位后面的数据(8位)
                    );
                }
                return $rez;
                break;
            default ://加密
                $t=explode(" ",microtime());
                $u = substr(uniqid(),-8);//13位截取后8位

                return sprintf( '%08s-%04s-%04s-%04s-%04x%08s',
                    substr("00000000".dechex($t[1]),-8),   // get 8HEX of unixtime
                    substr("0000".dechex(round($t[0]*65536)),-4), // get 4HEX of microtime
                    substr($u,0,4),//前4位
                    substr($u,-4),//后4位
                    $this->set['sid'],//$serverID,
                    dechex(ip2long(request()->getClientIp())));
                break;
        }
    }

}

使用方法

// Aes加密解密
$aes = Encrypt::init('aes', ['key' => '12345678','iv' => '1111111111111111',]);
$mi = $aes->aes('Hello World');
$ming = $aes->($mi,'dec')
// uuid加密解密
$uu = Encrypt::init('uuid', ['sid' => '1']);
$uuid = $uu->uuid();
$ming = $uu->($uuid,'dec')

结语

都是简单实现了一下哈，如果业务需求，可以扩展哦！升级更多功能 ～ 喜欢就点赞吧！
