How to check certificate name and alias in keystore files?

To check the certificate name and alias in a keystore file, you can use the keytool utility that comes with the Java Development Kit (JDK).

Here's the basic syntax for listing the contents of a keystore file:

keytool -list -keystore keystore_filename

Replace keystore_filename with the name of your keystore file. When you run this command, keytool will prompt you for the keystore password.

This will list the aliases of all the certificates in the keystore, along with some other information about each certificate. To display the certificate for a particular alias, you can use the -v option:

keytool -list -v -keystore keystore_filename -alias alias_name

Replace alias_name with the alias of the certificate you want to view. This will display the certificate chain for the specified alias, along with some other information about the certificate.

You can also use the -keystore and -alias options with other keytool commands to perform other operations on the keystore and its certificates. For example, you can use -importcert to import a certificate into the keystore, or -delete to delete a certificate from the keystore.

For more information about using keytool, you can use the keytool -help command or consult the Oracle documentation.
