php - 在 PHP 中使用 openssl_pkcs12_export 导出链

Question

是否可以使用 PHP 的 openssl_pkcs12_export() 将证书和私钥与证书链(根证书和/或中间证书)一起导出到 .pfx ？

更新:我查看了 php openssl 扩展的源代码，发现 openssl_pkcs12_export() 支持文档中的 2 个参数，friendly_name 和 >提取物。这来自 ext/openssl/openssl.c，查看第 1914-1920 行 (PHP-5.4.0):

1878 /* {{{ proto bool openssl_pkcs12_export(mixed x509, string &out, mixed priv_key, string pass[, array args])

1939 cleanup:

1943         }
1944         if (certresource == -1 && cert) {

1946         }
1947 }
1948 /* }}} */

但是，我不太确定如何将附加证书作为参数传递...有什么线索吗？

如果没有行号更容易阅读，请告诉我

这是 a bug that has been brought up将近两个月前。

谢天谢地，他为文档提供了一个示例补丁:

$args = array(
               'extracerts' => $CAcert,
               'friendly_name' => 'My signed cert by CA certificate'
              );
openssl_pkcs12_export($signed_csr, $cerificate_out, $private_key_resource, $passphrase, $args);

什么是$CAcert？在内部它被传递给一个函数 takes an array and turns it into a x509并且该函数还检测它是证书数组还是单个证书。如果传递的是数组，每个元素都应该是 x509 资源；如果传递的不是数组，则 $CAcert 应该是单个资源。 openssl_x509_read 可能是您想在此处使用的内容，因为它返回 $CAcert 中预期的 x509 资源类型。

有人说保持文档更新是 PHP 项目中最难的部分之一。如果您不擅长 C 并希望帮助 PHP 变得更好，那么这是一个很好的起点。
