使用PHP中的openssl_pkcs12_export导出链

Question

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

更新:我已经看了php openssl扩展的源代码,发现它openssl_pkcs12_export()支持2个args而不是文档中的那些,friendly_name和extracerts.这是来自ext/openssl/openssl.c,查看1914-1920行(PHP-5.4.0):

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

1902                 return;
1903         }
1904         priv_key = php_openssl_evp_from_zval(&zpkey, 0, "", 1, &keyresource TSRMLS_CC);

1919                 ca = php_array_to_X509_sk(item TSRMLS_CC);
1920         /* end parse extra config */
1921 
1922         p12 = PKCS12_create(pass, friendly_name, priv_key, cert, ca, 0, 0, 0, 0, 0);

1924         bio_out = BIO_new(BIO_s_mem());

1930                 ZVAL_STRINGL(zout, bio_buf->data, bio_buf->length, 1);
1931 
1932                 RETVAL_TRUE;
1933         }
1934 
1935         BIO_free(bio_out);
1936         PKCS12_free(p12);
1937         php_sk_X509_free(ca);
1938 
1939 cleanup:
1940 
1941         if (keyresource == -1 && priv_key) {
1942                 EVP_PKEY_free(priv_key);
1943         }
1944         if (certresource == -1 && cert) {
1945                 X509_free(cert);
1946         }
1947 }
1948 /* }}} */

但是,我不太确定如何将附加证书作为参数传递......任何线索？

如果没有行号,它是否更容易阅读,请告诉我

Answer 1

这是近两个月前提出的一个错误.

值得庆幸的是,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$CAcert？在内部,它被传递给一个函数,该函数接受一个数组并将其转换为x509,该函数还检测它是一个证书数组还是一个证书.如果要传递数组,则每个元素应为x509资源;如果未传递数组,则$ CAcert应为单个资源.openssl_x509_read很可能你想在这里使用它,因为它返回了预期的x509资源类型$CAcert.

有人说保持文档更新是PHP项目中最难的部分之一.如果你对C不好,并希望帮助PHP变得更好,那么这是一个好的开始.
