How to check certificate name and alias in keystore 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 order to get all the details I had to add the -v option to romaintaz answer:

keytool -v -list -keystore <FileName>.keystore

You can run from Java code.

try {        File file = new File(keystore location);        InputStream is = new FileInputStream(file);        KeyStore keystore = KeyStore.getInstance(KeyStore.getDefaultType());        String password = "password";        keystore.load(is, password.toCharArray());        Enumeration<String> enumeration = keystore.aliases();        while(enumeration.hasMoreElements()) {            String alias = enumeration.nextElement();            System.out.println("alias name: " + alias);            Certificate certificate = keystore.getCertificate(alias);            System.out.println(certificate.toString());        }    } catch (java.security.cert.CertificateException e) {        e.printStackTrace();    } catch (NoSuchAlgorithmException e) {        e.printStackTrace();    } catch (FileNotFoundException e) {        e.printStackTrace();    } catch (KeyStoreException e) {        e.printStackTrace();    } catch (IOException e) {        e.printStackTrace();    }finally {        if(null != is)            try {                is.close();            } catch (IOException e) {                // TODO Auto-generated catch block                e.printStackTrace();            }    }

Certificate class holds all information about the keystore.

UPDATE- OBTAIN PRIVATE KEY

Key key = keyStore.getKey(alias, password.toCharArray());String encodedKey = new Base64Encoder().encode(key.getEncoded());System.out.println("key ? " + encodedKey);
