    intr Univer is best

    using a double transposition cipher with 4 rows and 4 columns, using the row permutation

    (1, 2, 3, 4) → (2, 4, 1, 3)

    and the column permutation

    (1, 2, 3, 4) → (3, 1, 2, 4)

    Do you actually know how to do "double transposition cipher" on paper?
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.

    Then (1) write down the steps you would do if you were doing it yourself (2) have the computer do each of those steps (3) done.
