How to check certificate name and alias in keystore files

Question

I have a bunch of  keystore files and need to find one with specific CN and alias  Is there a way to do it with keytool  jarsigner or some other tool  I found a way to check if specific keystore was used to sign a specific apk  but I also need to get the alias and certificate name in each of the files

You can run the following command to list the content of your keystore file (and alias name):

keytool -v -list -keystore .keystore

If you are looking for a specific alias, you can also specify it in the command:

keytool -list -keystore .keystore -alias foo

If the alias is not found, it will display an exception:

keytool error: java.lang.Exception: Alias does not exist

In a bash-like environment you can use   keytool -list -v -keystore cacerts jks   grep  Alias name     grep -i foo   This command consist of 3 parts  As stated above  the 1st part will list all trusted certificates with all the details and that s why the 2nd part comes to filter only the alias information among those details  And finally in the 3rd part you can search for a specific alias  or part of it   The -i turns the case insensitive mode on  Thus the given command will yield all aliases containing the pattern  foo   f e  foo  123 FOO  fooBar  etc  For more information man grep
