Reading and writing to java KeyStore
-

Question
My app needs only to read private keys(with associated public cert), no writing to KeyStore, no password changing, no changes at all - just reading. Does anybody know for sure that for reading I can use this code:
///doing some actions
KeyStore store = KeyStore.getInstance("foo", "bar");
store.load(iaminputstream, iampwd); // I'M JUST LOADING, I'M NOT GONNA STORE IT!
PrivateKey pk = (PrivateKey) store.getKey(iamalias, iamkeypass);
Certificate cert = store.getCertificate(iamalias);
///contnuing some actions
instead of this:
///doing some actions
KeyStore store = KeyStore.getInstance("foo", "bar");
try{
store.load(iaminputstream, iampwd); //I'VE LOADED
PrivateKey pk = (PrivateKey) store.getKey(iamalias, iamkeypass);
Certificate cert = store.getCertificate(iamalias);
} finally {
store.store(iamoutputstream, iampassword); //AND I'VE SAVED!
}
///contnuing some actions
Prove link is highly appreciated!
La solution
You don't need to save it of course. Just don't forget to handle exceptions. Take a look at javadoc - there is nothing about required saving after load() call.
Autres conseils
If you are not storing anything, you don't have to call store.store()
But do remember to close the inputstream and handle exceptions.
