I am currently developing a QuickFIX/J application running on Java 17, intended to establish a secure connection with an external party using provided JKS certificates. Upon attempting the connection, I am encountering a java.security.cert.CertificateException with the message Certificates do not conform to algorithm constraints.

Here are the details:

• QuickFIX/J version: 2.3.1
• Java version: 17
• Error Message: java.security.cert.CertificateException: Certificates do not conform to algorithm constraints

I have attached the relevant portions of my QuickFIX/J configuration and the stack trace of the error. Could anyone provide advice on how to resolve this certificate issue or suggest any configurations that might prevent this error?

Thank you very much for any help you can provide!

My QuickFIX/J configuration

ConnectionType=initiator
SocketConnectHost=my_ip
SocketConnectPort=my_port
SocketUseSSL=Y
CipherSuites=TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384
EnabledProtocols=TLSv1.2
SocketKeyStore=/path/cert.jks
SocketKeyStorePassword=my_passowrd
SocketTrustStore=/path-trust/truststore.jks
SocketTrustStorePassword=my_password

My error

Requirements from the party to the connection

Listing the cipher suites textually:

• TLS_ECDHE_RSA_AES_256_GCM_SHA384
• TLS_ECDHE_RSA_AES_256_CBC_SHA384
• TLS_ECDHE_RSA_AES_128_CBC_SHA256

In this post QuickFIX/J CipherSuites , I received a tip on what CipherSuites I need to inform.
