When requesting a block cipher in stream cipher mode (for example; AES in CFB or OFB mode), a client may optionally specify the number of bits to be processed at a time, by appending this number to the mode name as shown in the following sample transformations:Cipher c1 = Cipher....
other by sending and receiving byte streams over a connection. To send a message from your application to another application, you need to know the IP address as well as the port number of the socket of the other application. In Java, a socket is represented by the java.net.Socket class...

This works fine in one class. In another class we use Raw InputStream is = Class.class.getResourceAsStream(FILENAME); Because that class is a singleton and is set up with static methods so getClass() won't work. We also tried Classloader.getResourceAsStream(FILENAME) but that didn't...
