这篇文章主要介绍了PHP实现加强版加密解密类,实例分析了php加密解密的相关实现技巧,具有一定参考借鉴价值,需要的朋友可以参考下

本文实例讲述了PHP实现加强版加密解密类。分享给大家供大家参考。具体如下:

enkey=$key; } } //设置密钥 public function set_key($key){ $this->enkey=$key; } private function keyED($txt,$encrypt_key) { $encrypt_key = md5($encrypt_key); $ctr=0; $tmp = ""; for ($i=0;$ienkey; } srand((double)microtime()*1000000); $encrypt_key = md5(rand(0,32000)); $ctr=0; $tmp = ""; for ($i=0;$ikeyED($tmp,$key)); $r=str_replace('=',$this->rep_char,$r); return $r; } //解密字符串 public function decrypt($txt,$key='') { $txt=str_replace($this->rep_char,'=',$txt); $txt=base64_decode($txt); if(!$key){ $key=$this->enkey; } $txt = $this->keyED($txt,$key); $tmp = ""; for ($i=0;$i

希望本文所述对大家的php程序设计有所帮助。
