需要安装对应PHP版本的gnupg扩展
// 设置gnupg在你本机的路径
putenv('GNUPGHOME=/root/.gnupg');
try {
//获取公钥
$publicKey = file_get_contents('application/report/pubkey.txt');
//初始化gpg
$gpg = new gnupg();
//开启调试
$gpg->seterrormode(gnupg::ERROR_EXCEPTION);
//导入公钥
$info = $gpg->import($publicKey);
//获取公钥指纹
$gpg->addencryptkey($info['fingerprint']);
//获取需要加密的文件
$uploadFileContent = file_get_contents($filename);
//加密文件
$enc = $gpg->encrypt($uploadFileContent);
//保存文件到本地
$filename = 'application/report/'.'file_xls' . '.gpg';
file_put_contents($filename, $enc);
} catch (Exception $e) {
//log something
return $e->getMessage();
}
