+# Ejemplo de creación de una credencial con verificaciones previas
+
+Al momento de crear una *credencial* (`Credential`), es posible que queramos verificar la creación con
+una lista detallada de errores. Si bien esto puede significar una doble verificación, es posible implementarlo
+con el siguiente código de ejemplo:
+
+```php
+<?php
+
+declare(strict_types=1);
+
+use Exception;
+use PhpCfdi\Credentials\Certificate;
+use PhpCfdi\Credentials\Credential;
+use PhpCfdi\Credentials\Internal\SatTypeEnum;
+use PhpCfdi\Credentials\PrivateKey;
+use Throwable;
+
+function createCredential(
+    string $certificateFile,
+    string $privateKeyFile,
+    string $passPhrase,
+    string $expectedRfc,
+     SatTypeEnum $expectedType
+): Credential {
+    try {
+        $certificate = Certificate::openFile($certificateFile);
+    } catch (Throwable $exception) {
+        throw new Exception('El archivo de certificado no se pudo abrir.', 0, $exception);
+    }
+    if ($certificate->rfc() !== $expectedRfc) {
+        throw new Exception(sprintf('El certificado no pertenece al RFC %s.', $expectedRfc));
+    }
+    if ($certificate->validOn()) {
+        throw new Exception('El certificado no es vigente en este momento.');
+    }
+    if ($expectedType->isFiel() && ! $certificate->satType()->isFiel()) {
+        throw new Exception('El certificado no corresponde a una eFirma/FIEL.');
+    }
+    if ($expectedType->isCsd() && ! $certificate->satType()->isCsd()) {
+        throw new Exception('El certificado no corresponde a un CSD.');
+    }
+
+    try {
+        $privateKey = PrivateKey::openFile($privateKeyFile, $passPhrase);
+    } catch (Throwable $exception) {
+        throw new Exception('El archivo de llave privada no se pudo abrir, el archivo o la contraseña son incorrectos.', 0, $exception);
+    }
+    if (! $privateKey->belongsTo($certificate)) {
+        throw new Exception('La llave privada no es par del certificado.');
+    }
+
+    return new Credential($certificate, $privateKey);
+}
+```
