Certificate used to enable SSL communication

[csolamx]

Hi,

I am using librdkafka through confluent-kafka-dotnet. I need to know what's the actual certificate being used to establish SSL/TLS communication with the Kafka brokers. I enabled the security conext for debugging and I get the following messages:

OPENSSL|rdkafka#consumer-1| [thrd:app]: Using OpenSSL version OpenSSL 3.0.8 7 Feb 2023 (0x30000080, librdkafka built with 0x30000080)
CERTSTORE|rdkafka#consumer-1| [thrd:app]: 72 certificate(s) successfully added  from Windows Certificate Root store, 0 failed
SSL|rdkafka#consumer-1| [thrd:app]: Loading public key from file *********.pem
SSL|rdkafka#consumer-1| [thrd:app]: Loading private key from file *********.pem

INIT|rdkafka#consumer-1| [thrd:app]: librdkafka v2.3.0 (0x20300ff) rdkafka#consumer-1 initialized ...

I guess this is the most information I will get from the library. Can I be sure that, with this output, the library is using the certificate I provided through SslCertificateLocation and not some certificate from the Windows Store (since it's still loading them)?

Thank you,
