Go through the code /* Brute Force Engine , by koby ( koby () in gr ) * * http://www.codecraft.tk * Finds every possible combination of ASCII * characters, which are between 33 - 126. The * characters between 33-126 are all of the * possible chars allowed on our keyboard * including special chars. * If you want to print those strings on screen, * remove the // on line 81 and notice the * difference with the time elapsed ... * Copyright (c) 2003 * koby and www.CodeCraft.tk.
