All the Above answers are nonsense, being java developers we all should know that there is a function called:

Java KeyStore to store the autogenerated keys Here is the code, I figured out on my own. This Code is just small piece i have posted not complete code. Just to give you guys an Idea

 final String keyStoreFile = "C:\\mykey.jceks";// Storing the Key in a Particulary.
 KeyStore keyStore = createKeyStore(keyStoreFile, "java143");
 System.out.println("Stored Key: " + (secKey));
 System.out.println("secured key: " + (keyStore));


 // store the secret key
 KeyStore.SecretKeyEntry keyStoreEntry = new KeyStore.SecretKeyEntry(secKey);
 //Padding for password
 PasswordProtection keyPassword = new PasswordProtection("pw-secret".toCharArray()); 

 keyStore.setEntry("mySecret", keyStoreEntry, keyPassword);
 keyStore.store(new FileOutputStream(keyStoreFile), "java143".toCharArray());
