SSL certificate configured , how to make sure works

How to make sure ssl certificate we have configured on LTM is working?

 

Or how do I verify the certificates that I have recently configured is working properly ?

    Check that the MD5 sum of the cert and key match

    openssl x509 -noout -modulus -in /path/to/certificate.crt | openssl md5
    openssl rsa -noout -modulus -in /path/to/key.key | openssl md5
    

    Also, Navigate to the VIP URL and check if you get an SSL errors in chrome or firefox

    Greetings,

     

    The best test will be to simply connect with the popular web browsers and ensure:

     

    • The browser shows a green lock (or however that browser indicates a secure connection).
    • There are no warnings.
    • It is in fact the certificate you installed.

    There are also a number of "ssl certificate checker" sites available to test your URL.

     

    Hope this is what you were after and is somewhat helpful!
