DHPublicKey不符合算法约束

DHPublicKey不符合算法约束

问题描述：

我有一个使用LDAP来验证和授权用户的Java web应用程序（点燃实时xmpp服务器）。DHPublicKey不符合算法约束

最近，LDAP服务器将其密码套件升级为更安全的密码。在我降级/jre/lib/security/java.security文件中允许的最小keySize之前，我无法让我的应用程序与此LDAP服务器通信。

#jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 2048 
jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 1024

我加了JCE 8在应用程序使用的JRE来更新密码，新密码出现了（我用this program和之前相比并后）

我能在webapp的管理控制台的密码 - 具体做法是：

> *  TLS_DHE_RSA_WITH_AES_256_CBC_SHA 

> *  TLS_DHE_RSA_WITH_AES_256_CBC_SHA256 
> *  TLS_DHE_RSA_WITH_AES_256_GCM_SHA384

我用this program看到LDAP服务器用什么密码：

结果如下：

Testing server - upgraded endpoint 
Given this client's capabilities ([SSLv3, TLSv1, TLSv1.1, TLSv1.2]),    the server prefers protocol=TLSv1.2,  cipher=TLS_DHE_RSA_WITH_AES_256_GCM_SHA384 

Testing server - non-upgraded endpoint 
Given this client's capabilities ([SSLv3, TLSv1, TLSv1.1, TLSv1.2]),  the server prefers protocol=TLSv1.2, cipher=TLS_RSA_WITH_AES_128_CBC_SHA

，该应用可能跟老LDAP（在集群中的未升级端点）具有以下java.security设置：

jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 2048

当终点是升级后（它被放在F5负载均衡器后面），我无法让应用连接，直到降级最低keySize。 LDAP的证书链（新旧终端）没有改变。

openssl s_client -connect newLDAP:636

显示了2048公钥，因为它的oldLDAP，唯一不同的是更强的密码 - 也许TLS版本1比1.2取决于我试图从OpenSSL的的s_client.First机器上的OpenSSL的版本。

该应用程序的xmpp网络应用程序：5223和管理控制台：9091也使用SSL，并且每个这些也都有2048位公钥。

在应用程序的日志文件中的错误是：

"DHPublicKey does not comply to algorithm constraints"

上面我所提到的约束相信引用jdk.tls.disabledAlgorithms java.security文件属性。

我很困惑，为什么显然更安全的密码现在需要一个较小的最小keySize为应用程序和LDAP连接工作。

我必须错过某些东西或做错事。

下面是从应用程序的日志一些堆栈跟踪：

感谢任何见解， SM

我不确定你在问什么。服务器显然是在使用2048位之前使用1024位DH组。抱怨服务器管理员。 –

如何验证服务器（我假定您的意思是LDAP）正在使用1024位组？我提到用openssl s_client和Java SSLTest程序连接到LDAP服务器。 Openssl显示公钥是2048位，SSLTest程序显示TLS版本和密码。 –

+0

带有DHE密码套件的“公钥”有两个公钥，通常是RSA的长期身份验证公钥和每个连接都会改变的DH公钥。我总是使用ssllabs.com上的服务器测试工具来获得服务器SSL功能的良好配置。 –

答

更多的背景：

我扫描的另一台服务器（如Web服务器）的背后同样的F5新的LDAP服务器也在后面，但是ssllabs可以访问......并且看到了关键的交换评级是橙色的 - 例如支持1024个DH密钥...因此网络服务器被降级到B级。这可能是我需要降低java.security设置以连接到新的LDAP服务器的原因。

我在可访问的Web服务器（未升级的F5后面）上做了相同的ssllabs扫描，旧的LDAP也很可能落后，密钥交换是绿色的，但较弱的支持密码和不安全的协议支持导致F评分。

我想，这也许可以解释的事情，假设同一密码套件跨越贵宾用于对个人F5s。

由于James K. Polk（在注释）建议一个合理的解释和SSL分析工具的建议。

答

要在我自己的问题跟进，我敢肯定，我证实，它是新的LDAP系统的临时密钥交换问题，因为最初是由James K Polk建议！他的建议SSLyze也非常有帮助。

我在新旧LDAP系统上运行了以下命令，我认为新系统只支持1024位密钥交换，而旧系统甚至可能不会进行密钥交换，这可能是为什么更强DH的keySize设置在JRE的java.security文件中工作（例如，它没有被使用）。
