RandomPassword is a Java 1.4 application to generate random passwords given an alphabet (list of available characters), the length of each password (in characters), and the number of passwords required. The default alphabet uses letters and digits that most people can distinguish when written down on a piece of paper. This alphabet does not have to be unique, and may repeat characters so they are more likely to appear.
Java strings are encoded in UTF-16 format. Since this program randomly selects text from a string, you should not use characters above Unicode U+FFFF in your alphabet, or else an unmatched half may be taken from a surrogate pair. The correction for Java 5.0 or later is left as an exercise.
