    Unhappy IMplementing the DES algo

    HEy Guys,

    I have been given a deadline of 2 days to write in a java program for implementing the DES Algorithm. I was wondering is someone could help me with a source code that i could modify. If you guys have done it before. Well i have seen the alogorithm and i dont think i would be bale to do it in 2 days. THough i have started with the classes i expect in the program. Need a big favor from u guys.

    Thanks
    Jk

    Do you mean implement the algorithm from scratch?
    or
    write code that uses a proven implementation of the algorithm?

    I'm a professional crypto guy, and I am not sure I could do the first in two days.

    The javax.crypto classes implement it for you, and AES (which you really should use for new code).

    There are tutorials and code examples.

    Well, seems like it from scratch, no indication has been given to using javax.crypto classes. so right now i am just implementing generation of the key part and friday is the deadline, I still dont know if i can do it all till then. I will try to look inti the class as u said ...see if i can implement from there. any other suggestion?
