java 1.8中无服务器响应的SSL握手

Question

我正在使用Progress DataDirect(光荣...)Microsoft SQL Server 2012的JDBC驱动程序

我现在正在尝试使用具有适当java.security文件、罐子、无限强度密码套件的符合FIPS的信任存储与我的java客户端应用程序连接到它们。信任存储包含我自己的CA的自签名证书。使用的算法是RSA。

使用JDK 1.7.0_。之后，它只是通过连接重置断开连接。

此外，我还尝试过在不同的组合中单独设置这些属性，但是在JDK 1.8中没有一个有效。

• -Dhttps。协议=TLSv1
• -Dcom.sun.net.ssl。enableECC=false
• -Djdk.tls.client.protocols=TLSv1

JDBC 连接属性也是开/关的不同组合：

• 加密协议版本=TLS v 1.2
• 主机名称证书=my.host.com

我尝试了TLS 1.2、1.1和1，但都不起作用。

因为它与JDK 1.7一起工作，我倾向于认为JDK 1.8打破了这个机制。

JDK 1.8的调试日志包含此日志条目，这与JDK 1.7完全不同

我还能尝试什么来解决这个问题？不幸的是，切换回1.7对我来说不是一个选择，也不是可能的。

    properties.setProperty("CryptoProtocolVersion", "TLSv1.2");

    return properties;
  }

Answer 1

对我来说，升级到JDK8（更新191）失败了，因为它对允许（TLS）加密算法的更严格政策。我只是通过修改我的${jdk.home}/jre/lib/Security/java.security文件再次启用了3DES_EDE_CBC：

jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, \
    EC keySize < 224, 3DES_EDE_CBC

至：

jdk.tls.disabledAlgorithms=SSLv3, RC4, MD5withRSA, DH keySize < 768, \
    EC keySize < 224

或以编程方式：

java.security.Security.setProperty("jdk.tls.disabledAlgorithms", 
    "SSLv3, RC4, MD5withRSA, DH keySize < 768, EC keySize < 224");

或在Spring：

<bean class="org.springframework.beans.factory.config.MethodInvokingFactoryBean">
    <property name="targetClass" value="java.security.Security" />
    <property name="targetMethod" value="setProperty" />
    <property name="arguments">
        <list>
            <value>jdk.tls.disabledAlgorithms</value>
            <value>SSLv3, RC4, MD5withRSA, DH keySize &lt; 1024, EC keySize &lt; 224</value>
        </list>
    </property>
</bean>
