捕获到错误 MQException：2059 - MQRC_Q_MGR_NOT_AVAILABLE.Net Core Linux Docker 容器 IBM MQ，由密码规范不匹配引起

Question

I have a .net core managed client running in a Linux docker container. I am trying to connect to the IBM message queue using SSL and it connects successfully using TLS_RSA_WITH_AES_128_CBC_SHA256. I tested again by asking them to change the server to AES_256. However, when they switch to AES_256 ie I try the same on TLS_RSA_WITH_AES_256_CBC_SHA256 I get 2059 - MQRC_Q_MGR_NOT_AVAILABLE.

In windows, you can specify default the cipher spec by going to group policy editor. example. https://docs.microsoft.com/en-us/windows-server/security/tls/manage-tls My question is how do I do that in the docker container. My image used is from Microsoft dotnet/core/aspnet:3.1-buster-slim Here is my code for reference,

 private static string _host = "GH2134";
        private static int _port = 1414;
        private static string _channel= "AES256.TEST.CHANNEL";
        private static string _qmgr= "MQMGR";
        private static string _cipherSpec = "TLS_RSA_WITH_AES_256_CBC_SHA256";
        private static string _mqUser = "mymqUser";
        private static string _mqPassword = "mymqPassword@";   
        private static string _keyRepository = "*USER";
              
        var properties = new Hashtable();
        properties.Add(MQC.TRANSPORT_PROPERTY, MQC.TRANSPORT_MQSERIES_MANAGED);
        properties.Add(MQC.HOST_NAME_PROPERTY, _host);
        properties.Add(MQC.PORT_PROPERTY, _port);
        properties.Add(MQC.CHANNEL_PROPERTY, _channel);
        properties.Add(MQC.USER_ID_PROPERTY, _mqUser);
        properties.Add(MQC.PASSWORD_PROPERTY, _mqPassword);
        properties.Add(MQC.SSL_CIPHER_SPEC_PROPERTY,_cipherSpec);         
        properties.Add(MQC.SSL_CERT_STORE_PROPERTY, _keyRepository);
          
        var queueManager = new MQQueueManager(_qmgr, properties);
        Console.Write("Connection created successfully...\n\n");       

I checked the bash for installed root@097aa5a44f52:/app# ssl cyphers -v Didn't find it TLS_RSA_WITH_AES_256_CBC_SHA256 how did I add it, like in windows group policy editor

Update: I verified with downgrading the nuget version of IBM® Message Service Client for .NET Standard (XMS .NET) 9.2.2 to 9.1.4 I was surprised to know that I get the 2059 error also with TLS_RSA_WITH_AES_128_CBC_SHA256 so I am might also guess that this could be a bug in the IBM's client library?

Answer 1

I can answer my own question. I did the tests with older library version of IBMXMS nuget packages. It did not support AES 128 as well, There is currently a bug in the official IBMXMS .net library that it does not support CYPHERSPECS TLS_RSA_AES_ 256 _WITH_RSA_SHA256 in the latest one. It supports AES128

However this is the case only in the Linux environment. In windows AES 256 works, provided that its also changed to the same spec in group policy. Here is a link on how to it https://docs.microsoft.com/en-us/windows-server/security/tls/manage-tls

Hence if you are using IBMs.Net Client Core in Linux, then only upto TLS_RSA_AES_ 128 _WITH_RSA_SHA256 unless IBM releases a new library dll or a nuget package that supports it. As of now the version I am using is from nuget, IBMXMSDotnetClient Version="9.2.2" in Openssl, there is already support
