Hello, Everyone In This Post I Will Guide You How To Make A Random Password Generate App In Sketchware.

At First Open You Sketchware App And Create A New Project As Shown In Below.


Now,After New Project Created Let's Start To Create Main UI Of Our App, So Follow Below Image And Put All Widget As Shown In Image .


After Completing Of Above UI Part ,Now We Have To Set Its ID.So,Select Each Widget And Change Its ID In Widget Properties As Per Given Below.

Change Check Box ID As Given Below:-

Check Box 1 Id As "upper"
Check Box 2 Id As "lower"
Check Box 3 Id As "num"
Check Box 4 Id As "sym"

Now,Change EditText1 Id As "max_length"

After All Id Set Now Create A New More Block With Name "PassGene" and Set It In OnCreate As Shown In Below.


Inside This More Block Put ASD Block And Put Below Code In ASD Block.


Code :-

}
private static String generateRandomPassword(int max_length, boolean upperCase, boolean lowerCase, boolean numbers, boolean specialCharacters)
{
String upperCaseChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
String lowerCaseChars = "abcdefghijklmnopqrstuvwxyz";
String numberChars = "0123456789";
String specialChars = "!@#$%^&*()_-+=<>?/{}~|";
String allowedChars = "";
Random rn = new Random();
StringBuilder sb = new StringBuilder(max_length);
/*code by Developer Partha*/
//this will fulfill the requirements of atleast one character of a type.
if(upperCase) {
allowedChars += upperCaseChars;
sb.append(upperCaseChars.charAt(rn.nextInt(upperCaseChars.length()-1)));
}
if(lowerCase) {
allowedChars += lowerCaseChars;
sb.append(lowerCaseChars.charAt(rn.nextInt(lowerCaseChars.length()-1)));
}
if(numbers) {
allowedChars += numberChars;
/*code by Developer Partha*/ sb.append(numberChars.charAt(rn.nextInt(numberChars.length()-1)));
}
if(specialCharacters) {
allowedChars += specialChars;
sb.append(specialChars.charAt(rn.nextInt(specialChars.length()-1)));
}
//fill the allowed length from different chars now.
for(int i=sb.length();i < max_length;++i){
/*code by Developer Partha*/ sb.append(allowedChars.charAt(rn.nextInt(allowedChars.length())));
}
return sb.toString();
}

{




After Set Above Code Go To Button 1 And Set Below Code In ASD Block

String pass = generateRandomPassword(Integer.parseInt(max_length.getText().toString()), upper.isChecked(), lower.isChecked(), num.isChecked(),sym.isChecked());

textview2.setText(pass);

This Will Generate The Random Password.

Now At Last Few Step In Button 2 Put CopyToClipBoard Block Along With TextView 2 As Shown Below.

All Done.So,Now Run Your App And Generate Random Password..

  1. Hey, I just see this good tutorial, and I've seen that there's a little exploit : When we generate a random password, it is not reeaaaally random, if you see some pictures, we can see that if you select upper char., lower char. and number, the password obligatory start with an upper char., then a lower char, and next a number. I think there's a little mistake in the code.

  2. Okay I think i've fix it :
    }
    private static String generateRandomPassword(int max_length, boolean upperCase, boolean lowerCase, boolean numbers, boolean specialCharacters)
    {
    String upperCaseChars = "ABCDEFGHIJKLMNOPQRSTUVWXYZ";
    String lowerCaseChars = "abcdefghijklmnopqrstuvwxyz";
    String numberChars = "0123456789";
    String specialChars = "!@#$%^&*()_-+=<>?/{}~|";
    Random random = new Random();
    String allowedChars = "";
    StringBuilder sb = new StringBuilder(max_length);

    if(upperCase){
    allowedChars += upperCaseChars;
    }

    if(lowerCase){
    allowedChars += lowerCaseChars;
    }

    if(numbers){
    allowedChars += numberChars;
    }

    if(specialCharacters){
    allowedChars += specialChars;
    }

    for(int i = sb.length(); i < max_length; i++){
    sb.append(allowedChars.charAt(random.nextInt(allowedChars.length())));
    }

    return sb.toString();

    }

    {
