How to Check Certificate Name and Alias in Keystore Files

Are you struggling to find the right keystore file among a bunch of .keystore files? Do you need to locate a specific CN (Common Name) and alias within these files? Fear not, for we have just the solution for you!

The Problem

Let's say you have multiple keystore files and you need to identify one that contains a specific CN and alias. You may have been wondering if there is a way to accomplish this using tools like keytool, jarsigner, or any other utility. Although you found a method to check if a particular keystore was used to sign a specific APK file, you also require the alias and certificate name within each of these mysterious .keystore files.

The Solution

You'll be relieved to know that you can achieve your goal using the trusty keytool utility. 🛠️

Here's how you can do it:

1. Open your command-line interface or terminal.

2. Navigate to the directory where your .keystore files are located.

3. Execute the following command:

   keytool -list -v -storepass [your_keystore_password] -keystore [keystore_file_name]

   Replace [your_keystore_password] with the actual password for your keystore file and [keystore_file_name] with the name of the keystore file you want to inspect.

4. Press Enter to run the command.

That's it! The keytool utility will display detailed information about the keystore, including the alias and certificate name.

Example Usage

Let's say you have a keystore file named my_keystore.jks with the password my_password. To check the certificate name and alias within this file, you would execute the following command:

keytool -list -v -storepass my_password -keystore my_keystore.jks

The output will provide you with a wealth of information about the keystore file, including the desired alias and certificate name.
