以下是我在organizationalUnit OU字段值<this is a test>中使用括号创建的示例CSR，phpseclib似乎无法返回此值。有没有解决这个问题？

使用phpseclib解析字段时，我得到以下输出：

[2] => Array
    (
        [0] => Array
            (
                [type] => id-at-organizationalUnitName
                [value] => Array
                    (
                        [utf8String] => 
                    )

            )

    )

通过命令行进行本地openssl读取OU字段没有问题。

openssl req -text -noout -verify -in ouissue.txt
verify OK

通过使用htmlentities();显示脚本标记解决，否则浏览器只是将其读取为html。

e.g。 echo htmlentities($x509->getDNProp('OU'));
