Password Validation in Oracle APEX with Example

Before the start,  we give you a suggestion that you should learn REGEXP_LIKE first then started this implementation or if you already know about REGEXP_LIKE then you can easily understand Password Validation implementation.

In this implementation, we follow some patterns for password validation in Oracle APEX

  • ^.*[0-9]
  • ^.*[a-z]
  • ^.*[A-Z]
  • ^.*[!@#$%^&*()_]

Now we are explaining the above regular expressions pattern.

  • ^ This pattern used for Matches the beginning of the string.
  • .  This pattern used for Matches any character except NULL.
  • * This pattern used for Matches zero or more occurrence.
  • [] This pattern used for the specified matching list with the help of this pattern you can match any of the characters in the list.
  • c This pattern used for matches case-sensitive.
We will follow the below password policies in this section.
  • Password Length must be 8 characters and not more than 15 characters.
  • The password must have one numeric value.
  • The password must have one LowerCase.
  • The password must have one UpperCase.
  • The password must have one special character.


Now follow the below steps for Password Validation in Oracle Apex with Example.

Step 1:-Create a Page with a Password field Item and also create a button. Below Screenshot will help you out for better understand. But here I am choosing a text field item because at the end of the post I will share a demo link where you can easily do testing.


Step 2:- Now choose password type item, right-click with the mouse, and create a validation. The below screenshot will help you out to better understand.



Step 3:-After creating a validation choose PL/SQL Function Returning Error Text validation type and add below PL/SQL code in function returning error text section. Below Screenshot will help you out.


BEGIN
IF 8 <= LENGTH(:P22_PASSWORD) AND  LENGTH(:P22_PASSWORD) <= 15  THEN
    IF REGEXP_LIKE(:P22_PASSWORD, '^.*[0-9]') THEN
 IF REGEXP_LIKE(:P22_PASSWORD, '^.*[a-z]', 'c') THEN
 IF REGEXP_LIKE(:P22_PASSWORD, '^.*[A-Z]', 'c') THEN
 IF REGEXP_LIKE(:P22_PASSWORD, '^.*[!@#$%^&*()_]', 'c') THEN
 RETURN '';
 ELSE
    RETURN 'Password has not one special character';
 END IF;
 ELSE
    RETURN 'Password has not one UpperCase';
 END IF;   
 ELSE
    RETURN 'Password has not one LowerCase';
 END IF;
 ELSE
    RETURN 'Password has not a numeric value';
 END IF; 
ELSE
RETURN 'Password Length Must be min 8 char and max 15 char
and your password length is'||' '||LENGTH(:P22_PASSWORD);
END IF;

END;

Step 4:- Now you have to run your page and check that if you write the correct password then it will display a success message otherwise, it will display an error message. Below Screenshot will help you out for better understand.
