Component body
A field that stores a unique Social Security or Tax ID number in a in a hashed field for security and maintains the last 4 digits for identification/display purposes.
The ssn storage module allows per field storage of validated unique social
security and tax id numbers.
Features:
- Unique ssn
- Basic ssn validation
- Hashed ssn
- Last 4 digits stored seperately for display
Use
Replace 'your_content_type' in examples below with the machine name of your
content
Add the field 'Social Security Number' to your_content_type/admin/structure/types/manage/your_content_type/fields
Select how you want your field to look:/admin/structure/types/manage/your_content_type/display
- Last 4 digits (####)
- Last 4 digits with hidden (***-**-####)
Security
The full social security number is hashed based on the salt in the settings.php
for drupal. If an attacker gets php eval permission or your settings.php file
is stolen along with your database it would be fairly trivial to expose hashed
social security numbers.
