PHP_EOL; $html .= "<br> BLENC file to encode: " . $file_name . PHP_EOL; //file_put_contents('blencode-log', "---\nFILE: $file_name\nSIZE: ".strlen($contents)."\nMD5: ".md5($contents)."\n", FILE_APPEND); $redistributable_key = blenc_encrypt($contents, TARGET_DIR . '/blenc/' . $file_name, $unencrypted_key); $html .= "<br> BLENC size of content: " . strlen($contents) . PHP_EOL; /** * Server key * key_file.blenc */ file_put_contents(TARGET_DIR . '/blenc/' . 'key_file.blenc', $redistributable_key . PHP_EOL); $html .= "<br> BLENC redistributable key file key_file.blenc updated." . PHP_EOL; exec("cat key_file.blenc >> /usr/local/etc/blenckeys"); echo $html; ?> 另一个php加密扩展https://github.com/liexusong/php-beast 和这个差不多。 php-beast 加密代码使用方法如下，在cli下运行 <?php function getext($file) { $list = explode('.', $file); return strtolower($list[count($list)-1]); } function encrypt_project($project, $new_project) { $project = rtrim($project, '/'); $new_project = rtrim($new_project, '/'); if (!file_exists($new_project)) { if (!mkdir($new_project)) { printf("[failed] failed to call `mkdir()' function\n"); return false; } } $hdl_o = opendir($project); $hdl_n = opendir($new_project); if (!$hdl_o || !$hdl_n) { if ($hdl_o) closedir($hdl_o); if ($hdl_n) closedir($hdl_n); printf("[failed] failed to call `opendir()' function\n"); return false; } while (($file = readdir($hdl_o)) !== false) { if ($file == '.' || $file == '..') { continue; } $path = $project.'/'.$file; if (is_dir($path)) { encrypt_project($path, $new_project.'/'.$file); } elseif (is_file($path) && getext($file) == 'php') { beast_encode_file($path, $new_project.'/'.$file); } else { copy($path, $new_project.'/'.$file); } } closedir($hdl_o); closedir($hdl_n); return true; } $stdin = fopen("php://stdin", "r"); $stdout = fopen("php://stdout", "w"); if (!$stdin || !$stdout) { if ($stdin) fclose($stdin); if ($stdout) fclose($stdout); exit("[failed] failed to open I/O stream\n"); } fwrite($stdout, "Please enter project path: "); $project = fgets($stdin); $project = trim($project); fwrite($stdout, "Please enter output project path: "); $new_project = fgets($stdin); $new_project = trim($new_project); $start = time(); fwrite($stdout, "Encrypting...\n"); encrypt_project($project, $new_project); /* encrypt project */ $spend = time() - $start; fwrite($stdout, "Finish encrypt, spend {$spend} seconds.\n"); ?> good: <?php /** * FileName: encrypt_project.php * Desc: php源码加密 * Author: Lenix * Email: yangyb@itv.cn * HomePage: http://www.itv.com.cn * Version: 1.0 * LastChange: 2015-08-03 13:34:56 * History: */ function getext($file) { $list = explode('.', $file); return strtolower($list[count($list)-1]); } function encrypt_project($project, $new_project) { $unencrypted_key='itvyyb';//个人密钥 $project = rtrim($project, '/'); $new_project = rtrim($new_project, '/'); if (!file_exists($new_project)) { if (!mkdir($new_project)) { printf("错误，不能调用 `mkdir()' 函数\n"); return false; } } $hdl_o = opendir($project); $hdl_n = opendir($new_project); if (!$hdl_o || !$hdl_n) { if ($hdl_o) closedir($hdl_o); if ($hdl_n) closedir($hdl_n); printf("错误，不能调用`opendir()' 函数\n"); return false; } while (($file = readdir($hdl_o)) !== false) { if ($file == '.' || $file == '..') { continue; } $path = $project.'/'.$file; if (is_dir($path)) { encrypt_project($path, $new_project.'/'.$file); } elseif (is_file($path) && getext($file) == 'php') { $source_code = file_get_contents($path); $contents = preg_replace(array('/^<(\?|\%)\=?(php)?/', '/(\%|\?)>$/'), array('',''), $source_code); $redistributable_key = blenc_encrypt($contents, $new_project.'/'.$file, $unencrypted_key); file_put_contents( 'key_file.blenc', $redistributable_key .
