Custom Password Rules for EBS 12.1.3

@#$%^&amp

Hi,

We want to implement following Password rules for EBS 12.1.3 instance;

Password must contain atleast 1 character from the following 4 types;
    a) Upper case letters (e.g., A, B...Z)
    b) Lower case letters (e.g., a, b...z)
    c) Numbers (e.g., 0, 1...9)
    d) Special characters (~`!@#$%^&amp;*()-_+=}{][|\;:"<>,./?)

The doc - ID 362663.1 is not available for public view, created SR to make it accessible,

I have tried to modify and implement a class file based on the below blog link;

having trouble to enforce the special character, the password sans special characters were getting accepted;
