Re: [fpc-pascal] HMAC_SHA1 and FPC

[silvioprog]

My function is more fast that cHash (
http://fundementals.sourceforge.net/dl.html). The comparison result is:

HMAC: 00:00:01:689 cHash: 00:00:02:038

My final unit is:

http://pastebin.com/4484g9i8

The code used in comparison:

uses
  HMAC, cHash;

procedure TForm1.Button1Click(Sender: TObject);
var
  i: Integer;
  b, e: TDateTime;
  x: string;
begin
  b := now;
  for i := 0 to 300000 do
    x := HMACSHA1('secret', 'The quick brown fox jumped over the lazy
dog.');
  e := now;
  Edit1.Text := 'HMAC: ' + FormatDateTime('hh:nn:ss:zzz', b - e);
  b := now;
  for i := 0 to 300000 do
    x := SHA1DigestToHex(CalcHMAC_SHA1('secret', 'The quick brown fox
jumped over the lazy dog.'));
  e := now;
  Edit1.Text := Edit1.Text + ' cHash: ' + FormatDateTime('hh:nn:ss:zzz', b
- e);
end;

I reinvented the wheel, but I can run faster now. :)

Thanks guys!
