ActiveMQ bad certificate when introduce SSL - ssl

Question

I am trying to use openwire+ssl in my ActiveMq. I am using the docker images provided by rmohr/activemq.
What I ran the following commands to generated necessary files since the broker_localhost.cert has expired.
keytool -genkey -alias broker -keyalg RSA -keystore broker.ks
keytool -export -alias broker -keystore broker.ks -file broker_cert
keytool -genkey -alias client -keyalg RSA -keystore client.ks
keytool -import -alias broker -keystore client.ts -file broker_cert
keytool -export -alias client -keystore client.ks -file client_cert
keytool -import -alias client -keystore broker.ts -file client_cert
Then in the activemq.xml I added:
<sslContext keyStore="file:${activemq.base}/certs/ActiveMq/broker.ks"
keyStorePassword="password" trustStore="file:${activemq.base}/certs/ActiveMq/broker.ts"
trustStorePassword="password"/>
as well as:
<transportConnector name="openwire+ssl" uri="ssl://0.0.0.0:61617?transport.enabledProtocols=TLSv1"/>
When I run docker compose to create the ActiveMQ instance I added an environment variable as:
environment:
- ACTIVEMQ_SSL_OPTS="-Djavax.net.ssl.keyStore=/opt/activemq/certs/ActiveMq/broker.ks -Djavax.net.ssl.keyStorePassword=password -Djavax.net.ssl.trustStore=/opt/activemq/certs/ActiveMq/broker.ts -Djavax.net.ssl.trustStorePassword=password -Djavax.net.debug=ssl,handshake"
After that I import the broker_cert generated in the previous steps in Windows Manage user certificates as Trusted Root Certification Authorities.
Then I build my Asp.Net Core project to access the ActiveMQ broker
var uri = new Uri(#"ssl://localhost:61617?trace=true&needClientAuth=true&transport.serverName='MoveQ Broker'");
ITransportFactory sslTransportFactory = new SslTransportFactory();
((SslTransportFactory)sslTransportFactory).SslProtocol = "Tls";
ITransport transport = sslTransportFactory.CreateTransport(uri);
_connection = new Connection(uri, transport, new IdGenerator());
((Connection)_connection).UserName = "username";
((Connection)_connection).Password = "password";
_session = _connection.CreateSession(AcknowledgementMode.AutoAcknowledge);
However I keep getting
activemq | WARN | Transport Connection to: tcp://172.17.0.1:35356 failed: javax.net.ssl.SSLHandshakeException: Received fatal alert: bad_certificate
Can anyone help to see what step(s) I may miss?

If you just need 1-way SSL and you're using self-signed certificates then you don't need a truststore on the broker or a keystore on the client. You just need a keystore on the broker and a truststore on the client. Generate these resources like so:
keytool -genkey -keystore broker-keystore.ks
keytool -export -keystore broker-keystore.ks -file broker.cer
keytool -import -keystore client-truststore.ks -file broker.cer
Then use broker-keystore.ks on the broker and client-truststore.ks on the client.
