I have some code for my app that creates a keystore in android,
creates some default keys then saves the keystore.
Later on the code tries to reload the keystore, on the emulator this
runs fine however when run on a phone I get an EOFException. Any
advice on where I'm going wrong?
An out take of the code is below:
In the class I have the following variables
static KeyStore keyStore;
String filenameKeyStore = "KeyStore.kstore";
Then the following two functions
public KeyHandler(Context context) {
if(keyStore == null) {
Log.d("KeyStore", "Keystore is null so loading");
if(initialiseKeyStore(context) == false) {
// KeyStore failed to initialise
Log.e("ERROR", "Store failed to initialise");
}
}
}
private boolean initialiseKeyStore(Context context) {
FileInputStream input = null;
try {
// Get an instance of KeyStore
keyStore = KeyStore.getInstance("BKS");
// Load the KeyStore file
try {
// Try and open the private key store
input = context.openFileInput(filenameKeyStore);
} catch (FileNotFoundException e) {
// If the file doesn't exist then create the
file, a ECDH key and
store the key
Log.w("Warning","File does not exist, creating
new file");
try {
// Load the default Key Store
keyStore.load(null, null);
// Create the file
FileOutputStream output =
context.openFileOutput(filenameKeyStore, 0);
// Reset private key
resetPrivateKey(context);
// Save the key
keyStore.store(output,
"password".toCharArray());
// Close the keystore and set the input
stream
output.close();
input =
context.openFileInput(filenameKeyStore);
// Reset the keyStore
keyStore = KeyStore.getInstance("BKS");
} catch (FileNotFoundException ee) {
Log.e("ERROR", "File not found, even
though we just created it");
return false;
} catch (NoSuchProviderException e1) {
// BC isn't working exit
e1.printStackTrace();
System.exit(1);
} catch (InvalidAlgorithmParameterException e1)
{
Log.e("ERROR", "The algorithm used for
secure algorithm is
incorrect");
e1.printStackTrace();
return false;
}
}
// Load the store
keyStore.load(input, "password".toCharArray());
} catch (KeyStoreException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
} catch (CertificateException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
} catch (EOFException e) {
// Where the exception is caught
e.printStackTrace();
return false;
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
} catch (NoSuchAlgorithmException e) {
// TODO Auto-generated catch block
e.printStackTrace();
return false;
} catch (NoSuchProviderException e) {
// Serious error, return
e.printStackTrace();
System.exit(1);
}
return true;
}
