Key key = keystore.getKey(alias, keyPassword) Keystore.load(new FileInputStream(keystoreFile), keyStorePassword) KeyStore keystore = KeyStore.getInstance(keyStoreType) īASE64Encoder encoder = new BASE64Encoder() Note that when the alias is not specified in the command, keytool will prompt you for it. The result will be the same keystore minus the deleted entry for the specified alias. This entry contains the private key and the certificate provided by the -in argument.
