这个库用于根据 SUNAT 规范对电子凭证进行签名。

需要 .PEM 格式的证书，可以参考以下示例将证书 .PFX 转换为其他格式：转换证书 .PFX。

安装

使用 composer 从 packagist 安装。

composer require greenter/xmldsig

示例

use Greenter\XMLSecLibs\Sunat\SignedXml;

require 'vendor/autoload.php';

$xmlPath = '20600995805-01-F001-1.xml';
$certPath = 'certifcate.pem'; // Antes convertir pfx -> pem (public+private key) 

$signer = new SignedXml();
$signer->setCertificateFromFile($certPath);

$xmlSigned = $signer->signFromFile($xmlPath);

file_put_contents("signed.xml", $xmlSigned);
