ssl - 无法连接到 WMQ 服务器 v7.0.1.14 的 TLS channel

Question

我的 Web 应用程序托管在 Websphere Application Server 中。对于所有传出连接，我们在服务器级别配置了动态 SSL 出站。目前，由于打补丁，SSLv3 已被禁用。现在，即使我们升级了出站 SSL 以支持 TLSV1.2，并使用基于 TLS 的 channel MQ channel ，与 WMQ 的连接仍然失败。详情如下。有人可以帮忙吗？

JAVA 中使用的密码套件 - SSL_RSA_WITH_AES_128_CBC_SHA256

Answer 1

WAS JVM 似乎无法与您在 MQ channel 上使用的密码套件一起使用。我的猜测是它在提示 SHA-2 签名算法。您可能需要使用无限制/无限制的导出策略文件。查看 IBM WAS manual 处的说明和 IBM Java SDK Security Guide .
