Description=Gammaprog is a bruteforce password cracker for web based e-mail address. (Currently only hotmail.com and usa.net address are supported.) The program is written in Java, so it should in theory run on any computer equiped with a Java virtual machine. It's not an applet however, it won't run from a web browser. If you don't have a Java virtual machine, you can get one at http://www.javasoft.com/products/index.html Get JDK or JRE. JRE is much smaller and if you have no java coding experience it is all you`ll probably need.
