Hello,
We are using Kafka for data uploading via SSL. While doing the SSL certificate
expiry test, we found that Kafka checks the expiry of keystore and does not
start when the current date exceed the validity end date of keystore and dump
the following exception in server.log
Hello,
Can anyone help me provide the below information:
Kafka SSL checks the validity of which SSL certificate: keystore or trust store
while checking the expiry condition?
Thanks in advance!
Best regards,
Deepak

Hello fellow Kafka users,
I have came across this behaviour of kafka while using it in SASL_SSL mode. My
observations are:
When we exclude the host.cer => Expiry date of certificate[1] in certificate
chain of Keystore is consider.
When we include the host.cer => No expiry is check even for all
Hi Luke,
We are using Kafka 2.8.1 Broker/Client system in our prod env. Due to the Log4j
vulnerability CVE-2021-44228, CVE-2021-45046, CVE-2021-4104 and CVE-2021-45105,
we are waiting for kafka to upgrade to Log4j 2.17. However, we came across
following link in which there is a preview for the
e.org/cve-list
If you are using non-upstream Kafka distro that includes log4j2, then check
with that vendor for additional information
I hope this helps

Hi Deepak,
The PR to upgrade to log4j 2 is already under review. And so far it looks good.
So I think it's possible to be merged into v3.2.0
Hi Luke,
Our application uses Java 8 but it seems the java 8 support is deprecated from

Kafka upcoming release 3.1.1?

backlashing the special character in the passwords and etc), but the issue

Please help us to understand the issue and provide any solution.
