delphi MD5 SHA1加密

MD5 SHA1 SHA2 能夠引用System.Hash單元

procedure TForm4.Button1Click(Sender: TObject);
var
  md5: THashMD5;
begin
  Edit2.Text := md5.GetHashString(Edit1.Text); //生成32字符長度的MD5
  Edit3.Text := md5.GetHMAC(Edit1.Text, 'jack'); //生成32字符長度的HMAC.
end;

procedure TForm4.Button2Click(Sender: TObject);
var
  sha1:THashSHA1;
begin
  Edit2.Text := sha1.GetHashString(Edit1.Text); //生成32字符長度的MD5
  Edit3.Text := sha1.GetHMAC(Edit1.Text, 'jack'); //生成32字符長度的HMAC.
end;
