This assumes you have reviewed Getting Started with IBM Global Security Key (GSKit).

Before viewing the details of a certificate in a Key Database, you will almost always first list the certificates in the Key Database.

~]# ${install_root}/gsk8/bin/gsk8capicmd_64 -cert -list -db /path/to/example.kdb -stashed
Certificates found
* default, - personal, ! trusted, # secret key
-  my_root_ca
-  my_intermediate_certificate
*- my_server_certificate

The -validate flag can then be used to determine if the certificates in the Key Database are valid.

~]# ${install_root}/gsk8/bin/gsk8capicmd_64 -cert -validate -db /path/to/example.kdb -stashed
my_root_ca : OK
my_intermediate_certificate : OK
my_server_certificate : OK

In this example, the details of my_server_certificate will be displayed.

~]# ${install_root}/gsk8/bin/gsk8capicmd_64 -cert -details -db /path/to/example.kdb -stashed
-label my_server_certificate
