Delphi dasturlash tilida tasodifiy parollar generatorini tuzish yo'llari

Bugun siz bilan Delphi dasturlash tilida tasodifiy parollar generatorini tuzishni ko’rib chiqamiz.

Delphi dasturlash tili uchun birorta IDE ni ishga tushiramiz. Men doimgiday Delphi7 ni ishga tushirdim.

Endi Ikkita Button va bitta Label qo’yib olamiz. Bular bizga protseduralarni ishga tushirish va tasodifiy parollarni chiqarish uchun kerak bo’ladi.

Bizda bosh class mavjud o’shani ichida public maydonida ikkita funksiya hosil qilamiz.

Bular :

    function RandomPassword(PLen: Integer): string;

    function RandomWord(dictSize, lngStepSize, wordLen, minWordLen: Integer): string;

endi bu funksiyalarni hosil qilish uchun ularni ustiga sichqonchani olib borib,

Shift+Ctrl+C tugmalarini bosing. O’shanda dastur kodida tepadagi funksiyalar hosil bo’ladi va ularni ichiga yozishimiz mumkin bo’ladi.

Sizga dasturni barcha kodini keltiraman :

    { Public declarations }

    //Bizga kerakli funksiyalarni e'lon qilamiz

    function RandomPassword(PLen: Integer): string;

    function RandomWord(dictSize, lngStepSize, wordLen, minWordLen: Integer):string;

 //Funksiya nomlarini o’zingiz hoxlagancha nomlashingiz mumkin.

  end;

var

  Form1: TForm1;

implementation

{$R *.dfm}

procedure TForm1.Button1Click(Sender: TObject);

begin

  //Label1 ni Caption xususiyatiga tasodifiy parollarni chiqaramiz

  Label1.Caption := RandomPassword(10);

end;

procedure TForm1.Button2Click(Sender: TObject);

begin

  //Form1 ni Caption xususiyatiga tasodifiy parollani chiqaramiz

  Caption := RandomWord(33, 54, Random(12), 2);

end;

function TForm1.RandomPassword(PLen: Integer): string;

var

   str: string; //harflar joylashishi uchun

begin

   Randomize; // Tasodifiy sonlar generatsiyasini ishga tushirish

   //Quyidagi kiritilgan harflardan foydalanib parol hosil qilamiz

   str  := 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ';

   Result := '';

   repeat

     Result := Result + str[Random(Length(str)) + 1];

   until (Length(Result) = PLen)

end;

function TForm1.RandomWord(dictSize, lngStepSize, wordLen,

  minWordLen: Integer): string;

begin

   Result := '';

   if (wordLen < minWordLen) and (minWordLen > 0) then

     wordLen := minWordLen

   else if (wordLen < 1) and (minWordLen < 1) then wordLen := 1;

   repeat

     Result := Result + Chr(Random(dictSize) + lngStepSize);

   until (Length(Result) = wordLen);

end;

end.

Ishlatish endi sizga, agar bu dasturga qo’shimchalar qilishni hoxlasangiz, izoh qoldiring!

Funksiyalarga tushunmagan bo’lsangiz, izoh qoldiring!

Eng avvalo tushunishga harakat qiling!

Savollaringiz bo’lsa izoh berish joyida qoldiring!  Birgalashib ishlaymiz!
