Increase your knowledge: check SSL certificate expiration date


Hi. I think the best way to check SSL certificate expiration date is by use of commands unique to each operating system. In case you are facing problems, they can be due to some other error In SSL certificate which can be checked with the help of an online SSL checker tool.

It is used to find out issues related to the validity, installation and whether the certificate is from a trusted source or not. The tool can be found and used from and then type in the server hostname and click on the button check SSL. Next, there are some commands which can be used to check the expiration date of the certificates which can be checked online or from websites such as IBM support.

Talking about the type of certificates,

• PEM certificate- When SSL engine connections are enabled, these certificates are used by the TWS.

• KDB certificate- These are used by the TWS to either verify the dynamic agents or to check the KDB Files

• JKS certificate- TWS ewas master, backup master, etc. use these certificates and stored in TWS 8.5.0 and 8.51 folders.
