base64+gzinflate壓縮編碼（加密）過的文件通常是以 <? eval(gzinflate(base64_decode( 為頭的一個php文件。以下我們給出了相關的編碼解碼（加密解密）代碼。
壓縮編碼（加密）代碼：
復制代碼 代碼如下:
<?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 並且可寫 則進行壓縮編碼
$contents = file_get_contents($filename);// 判斷文件是否已經被編碼處理
$pos = strpos($contents,'/*Protected by 草名 http://www.crazyi.cn Cryptation*/');
if(false === $pos || $pos>100){ // 去除PHP文件注釋和空白，減少文件大小
$contents = php_strip_whitespace($filename);
// 去除PHP頭部和尾部標識
$headerPos = strpos($contents,'<?php');
$footerPos = strrpos($contents,'?>');
$contents = substr($contents,$headerPos+5,$footerPos-$headerPos);
$encode = base64_encode(gzdeflate($contents));// 開始編碼
$encode = '<?php'." /*Protected by 草名 http://www.crazyi.cn Cryptation*/\n eval(gzinflate(base64_decode(".$encode.")));\n /*Reverse engineering is illegal and strictly prohibited- (C)草名 Cryptation 2008*/ \n?>";
return file_put_contents($filename,$encode);
}
}
return false;
}
//調用函數
$filename='g:\我的文檔\桌面\test.php';
encode_file_contents($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 並且可寫 則進行壓縮編碼
$contents = file_get_contents($filename);// 判斷文件是否已經被編碼處理
$pos = strpos($contents,'/*Protected by 草名 http://www.crazyi.cn Cryptation*/');
if(false === $pos || $pos>100){ // 去除PHP文件注釋和空白，減少文件大小
$contents = php_strip_whitespace($filename);
// 去除PHP頭部和尾部標識
$headerPos = strpos($contents,'<?php');
$footerPos = strrpos($contents,'?>');
$contents = substr($contents,$headerPos+5,$footerPos-$headerPos);
$encode = base64_encode(gzdeflate($contents));// 開始編碼
$encode = '<?php'." /*Protected by 草名 http://www.crazyi.cn Cryptation*/\n eval(gzinflate(base64_decode(".$encode.")));\n /*Reverse engineering is illegal and strictly prohibited- (C)草名 Cryptation 2008*/ \n?>";
return file_put_contents($filename,$encode);
}
}
return false;
}
//調用函數
$filename='g:\我的文檔\桌面\test.php';
encode_file_contents($filename);
?>
壓縮解碼（解密）代碼：
復制代碼 代碼如下:
<?php
$Code = '這裡填寫要解密的編碼'; // base64編碼
$File = 'test.php';//解碼後保存的文件
$Temp = base64_decode($Code);
$temp = gzinflate($Temp);
$FP = fopen($File,"w");
fwrite($FP,$temp);
fclose($FP);
echo "解密成功！";
?>
