this course. It is intended to be much easier to read
than the Handbook of Applied Cryptography.You are not allowed to print a copy of this book, especially not at UTSA. (The copyright holder does not allow printing the book. The printed copy will not do you much good and will waste a lot of paper. You may make an electronic copy for your own use.)
