• How to compare the current password encrypted pasword enter APEX4.1

  Hi all
  In my application uses the following package

  create or replace PACKAGE BODY app_security_pkg
  AS
  PROCEDURE login 
            (
             p_uname IN VARCHAR2
            ,p_password IN VARCHAR2
            ,p_session_id IN VARCHAR2
            ,p_flow_page IN VARCHAR2
            )
  IS
   lv_goto_page NUMBER DEFAULT 1;
  BEGIN
   
   -- This logic is a demonstration of how to redirect 
   -- to different pages depending on who successfully 
   -- authenticates. In my example, it simply demonstrates 
   -- the ADMIN user going to page 1 and all other users going
   -- to page 2. Add you own logic here to detrmin which page 
   -- a user should be directed to post authentication.
   IF UPPER(p_uname) = 'ADMIN'
   THEN
    lv_goto_page := 1;
   ELSE
    lv_goto_page := 2;
   END IF;
  
  APEX_UTIL.SET_SESSION_STATE('FSP_AFTER_LOGIN_URL');
  
   wwv_flow_custom_auth_std.login 
   (
    p_uname => p_uname,
    p_password => p_password,
    p_session_id => p_session_id,
    p_flow_page => p_flow_page || ':' || lv_goto_page
    );
  
  EXCEPTION
  WHEN OTHERS
  THEN 
   RAISE;
  END login;
  
  PROCEDURE add_user 
  (
   p_username IN VARCHAR2
  ,p_password IN VARCHAR2
  )
  AS
  BEGIN
  INSERT INTO app_users (username, PASSWORD)
      VALUES (UPPER (p_username),
          get_hash (TRIM (p_username), p_password));
  
  COMMIT;
  
  EXCEPTION
  WHEN OTHERS
  THEN 
   ROLLBACK; 
   RAISE;
  END add_user;
  
  -- Function to Perform a oneway hash of the users 
  -- passwords. This cannot be reversed. This exmaple 
  -- is a very week hash and if been used on a production 
  -- system, you may want to use a stronger hash algorithm.
  -- Read the Documentation for more info on DBMS_CRYPTO as 
  -- this is the supported package from Oracle and 
  -- DBMS_OBFUSCATION_TOOLKIT is now depricated.
  FUNCTION get_hash (p_username IN VARCHAR2, p_password IN VARCHAR2)
  RETURN VARCHAR2
  AS
  BEGIN
  RETURN DBMS_OBFUSCATION_TOOLKIT.md5 (
  input_string => UPPER (p_username) 
                  || '/' 
                  || UPPER (p_password));
  END get_hash;
  
  PROCEDURE valid_user2 (p_username IN VARCHAR2, p_password IN VARCHAR2)
  AS
  v_dummy VARCHAR2 (1);
  BEGIN
  SELECT '1'
  INTO v_dummy
  FROM app_users
  WHERE UPPER (username) = UPPER (p_username)
  AND PASSWORD = get_hash (p_username, p_password);
  EXCEPTION
  WHEN NO_DATA_FOUND
  THEN raise_application_error (-20000, 'Invalid username / password.');
  END valid_user2;
  
  FUNCTION valid_user (p_username IN VARCHAR2, p_password IN VARCHAR2)
  RETURN BOOLEAN
  AS
  BEGIN
  valid_user2 (UPPER (p_username), p_password);
  RETURN TRUE;
  EXCEPTION
  WHEN OTHERS
  THEN RETURN FALSE;
  END valid_user;
  
  END app_security_pkg;

  Here the ADD_USER procedure will convert the password and stores in the Table app_users in encrypted form.
  
  In my application, users can change their password,
  So I need to compare the password entering the Current_password field with the password encrypted in the app_users table.
  So I used the following code,

  declare
    l_x varchar2(30);
  begin
    select username into l_x
          from app_users
      where upper(username) = upper(:P7_USERNAME)
        and password = :P7_CURRENT_PASSWORD;
    return (true);
  exception
    when no_data_found then
      return (false);
  end;

  This code works fine when the password is stored without encryption, but it displays error, after encryption
  
  because the password entered is simply password and not encrypted if the two are different even if the user enters the correct password.
  
  Please tel me how encrypt the entered password to compare with the encrypted password.
  
  Thank you
  Kind regards

  Hi guru,.

  When you say comparing it is obvious that both must be in the same format, so either you have to compare both encrypted or not encrypted.

  Do you have an example on apex.oracle.com?

  Thank you

• How to jump the connection password re-boot...

  How to ignore the connection password re-boot while it self-connections me?

  In XP, TweakUI was a setting to do this, but it comes to Windows 7?

  There is an option for her, but it's pretty hidden, because it leaves your unsecured computer (anyone who circulated happens not only to all your files, but they can also get to any Web page you visited, like facebook or even your bank).

  If you are sure you want to do, here's how:
  1 - Press Windows-R to open the run, and then type the following command and press ENTER: control userpasswords2
  2 - clear the check box at the top (users must enter a password...) and then click OK
  3. set the default account, you want to connect to from the context menu that appears, and then click OK once more
  All together.

  Hi Karrah,

  You can try to check if you have any other user account on the computer and try to connect to this account and change the password for your user account.

  You can also access the link below to learn more about Microsoft's strategy concerning lost or forgotten passwords.

  http://support.Microsoft.com/kb/189126

  If you do not have any other user account on the computer, you may need to back up your data and contact the manufacturer of the computer for restore to factory settings or reinstall the operating system.

  I hope this helps.

  Thank you and best regards,
