I am using Drupal 7. I have a page that has a PHP body that I know does not have any dangerous tags. According to the README.txt file in Security Review I need to add this to the "security_review_known_risky_fields" system variable ? Can somebody provide an example on how to do this? I am not sure exactly what the entry in the variable table should look like.
The README says to create "a SHA-256 hash of the entity_id, entity_type, and field contents". It looks like you have to call
hash('sha256', $entity_id.$entity_type.$field_contents) and save that in the
security_review_known_risky_fields string variable, which can be done in settings.php. If there are multiple fields you want to allow, separate their respective hashes with commas.
