random pin generation

Automatical random PIN generation has been all the more common now, especially in mobile applications. There is a very good utility around by Stephen Ostermiller, that lets you generate random sequences of arbitrary length and arbitrary alphabets. You can download the latest Ostermiller Utils from and then use it directly from command line (java -classpath utils.jar com.Ostermiller.util.RandPass), or more commonly through your Java application:

String pass = new RandPass(new char[]{'A','B','C'}).getPass(8)
