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 compare the LDAP password

    Hello

    I am able to bind to the LDAP connection using the program java and able to search the DN of the user and get the userPassword attribute. I get encrypted password. My question is what is the encryption algorithm should I use to convert my password in plain text to compare with the password LDAP attribute?

    You do not compare the password entered with the LDAP password. You try to authenticate to the LDAP server as long as that user with the entered password. If you succeed, the password is correct. This is what is called an LDAP "bind" operation, not to be confused with the JNDI 'bind '. In JNDI, it's a reconnect().

  • Satellite P20-304 - how to remove the BIOS password

    Hi all

    a girlfriend of mine got a Satellite P20 304 with Phoenix Bios.
    She wanted that I remove the Bios password that must be entered directly after the Toshiba start screen.
    So, I entered Bios with F2, went to security, entered the old password and press enter two times to a new blank password.

    The Bios then showed that user password is not defined.
    I saved the changes and started to laptop came out, and asked me again a password.
    Now no entry (only press enter) or the old password works, still displays "wrong password".

    What I did wrong?

    I am a COMPUTER technician, but never had a problem like this.
    This problem is related to the Bios Phoenix or Toshiba? And how to solve the problem?

    Can anyone help? Would be fine, girlfriend needs urgent laptop.

    Thanks for the comments!

    Hello

    I have a password for the Toshiba Satellite A110-260, but I can't reset the password of the battery

    Please help me!

    How to reset the bios password

    You cannot remove the BIOS password. Something like that is not possible on Toshiba laptops.
    A special procedure is required and this can be done ONLY by a (certified partner) ASP.

    So my advice is to contact the ASP in your country and ask for help!
