| Description: | Command line program that allows a server to broadcast audio to a client. The server is started with java AudioServer and displays its address on the command line. Then the client can connect to the server with java AudioClient serverIp serverPort. After the connection took place, the microphone of the server records audio and sends it to the client where it is played back. The client can stop listening by pressing "q" which sends a disconnect message to the server. Connection is done via TCP. In the current implementation only a single client can connect to the server. |

| Description: | This command line program allows the user to hide a message in a
png image file. The program iterates over the pixels of the image. It
consequitively writes three bits of the message to each parsed pixel
until the whole message is hidden in the image. To do that the last bit
of each of the three color channels of a pixel is used to store a
single bit of the message. This manipulates the colors of the image in
a way that can not be recognized by the human eye. The syntax is as follows:
