This Visual Basic program is a passwords cracker where it can generate possible passwords and compare each of them with the actual password; and if the generated password found to be equal to the actual password, login will be successful. In this program, a timer is inserted into the form and it is used to do a repetitive job of generating the passwords.
generating procedure is put under the timer1_Timer () event so that the
procedure is repeated after every interval. The interval of the timer
can be set in its properties window where a value of 1 is 1 millisecond,
so a value of 1000 is 1 second; the smaller the value, the shorter the
interval. However, do not set the timer to zero because if you do that,
the timer will not start. The Timer1.Enabled property is set to false so
that the program will only start generating the passwords after you
click on the command button. Rnd is a VB function that generates a random number between 0 and 1.
Multiplying Rnd by 100 will obtain a number between 0 and 100. Int is a VB
function that returns an integer by ignoring the decimal part of that
