How to make the generator selective.

One more time, the simplest way to make our generator capable of creation of passwords with any combination of upper case letters, lower case letters... etc. is to make 4 buttons that control the value of 4 variables, one for every category of chars:

  • variable upp for upper case letter;
  • variable low for lower case letter;
  • variable num for numbers;
  • variable symb for symbols;

each variable can be "on" or "off"; status "on" means that the associated type of chars are enabled, status "off" means that the same are disabled. For example if upp="on", low="off", num="off", symb="on" then will be generated a password which contains only upper case letters and symbols.
But how these variables work? For every variable (i.e. for every category of symbols) it is associated a own "mini-alphabet", and precisely:

  • upper case letters -> upp -> "ABCDEFGHJKILMNOPQRSTUVWXYZ"
  • lower case letters -> low -> "abcdefghjkilmnopqrstuvwxyz"
  • numbers -> num -> "0123456789"
  • symbols -> symb -> "|!£$%&/()=?^'ìè+òàù-.,<é*ç°§;:_>[]@#{}"

the final alphabet is the sum of the 4 mini-alphabets. By putting "off" one of the 4 variables we exclude one mini-alphabet; for example if, as above, upp="on", low="off", num="off", symb="on", then the final alphabet will be:
and in the password generated will appear only those chars.

The new code is:

    m = 0;
password = "";
if (upp=="on") {
} else {
alf1 = "";
if (low=="on") {
alf2 = "abcdefghkjilmnopqrstuvwxyz";
} else {
alf2 = "";
if (num=="on") {
alf3 = "1234567890";
} else {
alf3 = "";
if (symb=="on") {
alf4 = "|!£$%&/()=?^'ìè+òàù-.,<é*ç°§;:_>[]@#{}";
} else {
alf4 = "";
alphabet = alf1+alf2+alf3+alf4;
alphL = alphabet.length;
for (m=0; m rn = Math.floor(Math.Random()*(alphL-1));
password = password+alphabet.charAt(rn);

this code must be associated to the "generate" button on the movie, as on(release) event.

» Description: Hmm... what to say about this one? It's reminiscent of the closing notes of the opening music from the Three Stooges done in a church organ style with a closing cymbal crash. I'll give this one away gratis, but feel free to check out my free loops and potential upcoming license-mandated ones over in the respective part of Flashkit.
