Title: To generate random password string
Question: How can I generate the random password in own program?
Answer:
In last holidays I wrote a small dialog for random password generation. It's a simple but results is very useful:))
Try it:
function TfrmPWGenerate.btnGenerateClick(Sender: TObject): string;
{max length of generated password}
const
intMAX_PW_LEN = 10;
var
i: Byte;
s: string;
begin
{if you want to use the 'A..Z' characters}
if cbAZ.Checked then
s := 'ABCDEFGHIJKLMNOPQRSTUVWXYZ'
else
s := '';
{if you want to use the 'a..z' characters}
if cbAZSmall.Checked then
s := s + 'abcdefghijklmnopqrstuvwxyz';
{if you want to use the '0..9' characters}
if cb09.Checked then
s := s + '0123456789';
if s = '' then exit;
Result := '';
for i := 0 to intMAX_PW_LEN-1 do
Result := Result + s[Random(Length(s)-1)+1];
end;
initialization
Randomize;
The sample results:
IBbfA1mVK2
tmuXIuQJV5
oNEY1cF6xB
flIUhfdIui
mxaK71dJaq
B0YTqxdaLh
...
I think that it's no bad:)) Of course, you can add the some additional crypt methods and check of unique.
