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。文中给出了编码和解码的代码。

php压缩编码(加密)源代码：

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  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

$encode = '<?php '." /*Protected Cryptation*/\n eval(gzinflate(base64_decode(".$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);

?>

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 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

$encode = '<?php '." /*Protected by  Cryptation*/\n eval(gzinflate(base64_decode(".$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压缩解码(php解密)源代码：

$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！";

?>
