Using OutputStream Class In Java 6 or below, you can use the OutputStream class to manually copy data from InputStream to a file as shown below: try (InputStream inputStream = new FileInputStream(new File("input.txt")); OutputStream outputStream = new FileOutputStream(new File("output....

FileInputStream keyfis = new FileInputStream(args[0]); byte[] encKey = new byte[keyfis.available()]; keyfis.read(encKey); keyfis.close(); Now the byte arrayencKeycontains the encoded public key bytes. You can use aKeyFactoryclass in order to instantiate a DSA public key from its ...
