Hi,
I need to write a method in Java for
encrypt a String with DES.
the interface is:
public String encrypt(String nameofthestringtoencript);
the return String have to be DES(nameofthestringtoencript)
What is the procedure to follow and the java methods
to do it?
Thanks in advance.

How odd... you'd expect the name of that parameter to be
"thestringtoencript", not "nameofthestringtoencript". Can you discuss with
your tutor (for extra points ;-)

Depends on which JDK you carry out your exercises. The solution could get
low-level if you're on a pre-1.4 platform.

Does the Java Tutorial not have a section on the security API?

Or maybe the Java Almanac...

I suggest getting a textbook. Trying to use the API without a guide is
daunting.
