PHP base64+gzinflate压缩编码和解码代码
base64+gzinflate压缩编码(加密)过的文件通常是以 <? eval(gzinflate(base64_decode( 为头的一个php文件。以下我们给出了相关的编码解码(加密解密)代码。
压缩编码(加密)代码:
复制代码 代码如下:
<?php function encode_file_contents($filename) { $type=strtolower(substr(strrchr($filename,'.'),1)); if('php'==$type && is_file($filename) && is_writable($filename)){// 如果是PHP文件 并且可写 则进行压缩编码 $contents = file_get_contents($filename);// 判断文件是否已经被编码处理 $pos = strpos($contents,'/*Protected by 草名 http://www.crazyi.cn Cryptation*/'); if(false === $pos || $pos>100){ // 去除PHP文件注释和空白,减少文件大小 $contents = php_strip_whitespace($filename); // 去除PHP头部和尾部标识 $headerPos = strpos($contents,'<?php'); $footerPos = strrpos($contents,'?>'); $contents = substr($contents,$headerPos+5,$footerPos-$headerPos); $encode = base64_encode(gzdeflate($contents));// 开始编码 $encode = '<?php'." /*Protected by 草名 http://www.crazyi.cn Cryptation*/\n eval(gzinflate(base64_decode(".$encode.")));\n /*Reverse engineering is illegal and strictly prohibited- (C)草名 Cryptation 2008*/ \n?>"; return file_put_contents($filename,$encode); } } return false; } //调用函数 $filename='g:\我的文档\桌面\test.php'; encode_file_contents($filename); ?> <?php function encode_file_contents($filename) { $type=strtolower(substr(strrchr($filename,'.'),1)); if('php'==$type && is_file($filename) && is_writable($filename)){// 如果是PHP文件 并且可写 则进行压缩编码 $contents = file_get_contents($filename);// 判断文件是否已经被编码处理 $pos = strpos($contents,'/*Protected by 草名 http://www.crazyi.cn Cryptation*/'); if(false === $pos || $pos>100){ // 去除PHP文件注释和空白,减少文件大小 $contents = php_strip_whitespace($filename); // 去除PHP头部和尾部标识 $headerPos = strpos($contents,'<?php'); $footerPos = strrpos($contents,'?>'); $contents = substr($contents,$headerPos+5,$footerPos-$headerPos); $encode = base64_encode(gzdeflate($contents));// 开始编码 $encode = '<?php'." /*Protected by 草名 http://www.crazyi.cn Cryptation*/\n eval(gzinflate(base64_decode(".$encode.")));\n /*Reverse engineering is illegal and strictly prohibited- (C)草名 Cryptation 2008*/ \n?>"; return file_put_contents($filename,$encode); } } return false; } //调用函数 $filename='g:\我的文档\桌面\test.php'; encode_file_contents($filename); ?>
压缩解码(解密)代码:
复制代码 代码如下:
<?php $Code = '这里填写要解密的编码'; // base64编码 $File = 'test.php';//解码后保存的文件 $Temp = base64_decode($Code); $temp = gzinflate($Temp); $FP = fopen($File,"w"); fwrite($FP,$temp); fclose($FP); echo "解密成功!"; ?>
