Take the following problem home.
Suppose the encrypted form of a password is stored as an array of
The above array is fully formed, and ready to send somewhere over a Socket.
Your job is to transmit the encrypted password as a sequence of
Color objects. Recall each Color object has
three 8-bit fields that indicate how much red, green, and blue is
in the Color.
While we won't try to compile your solution, please express your
answers in Java and pseudocode, in sufficient detail so the TAs can figure
out how you will do the above things.
Turn in the take-home part by 4 PM Monday, 7 April 2003 to my

First, show how a sequence of Color objects will represent the
above byte array. Try to be efficient in your use of the Color objects,
using all three, 8-bit fields if possible.
- You must then devise two protocols for transmitting
- (25 points) One sends the data in binary -- the data is
not printable ASCII characters in this case. The recipient must somehow
know how many Colors you will be transmitting, so be sure to include
that in your protocol.
- (25 points) The other sends the Color objects in ASCII, as a printable String.
Here, you can use a space or some kind of terminating character to mark
the end of what you transmit. The data you transmit must consist only
of lower-case letters and digits (ASCII 0, 1, 2, ... 9)
