A differentiation between WP and CP is that CP is business-focused by being an application development platform, not just for blogging. Part of business operation would be to store personal information which may need encryption due to GDPR recommendations or actual enforcement by data privacy laws. This petition suggests to include 2 functions to encrypt and decrypt data ( i.e. wp_encrypt() and wp_decrypt() ) which can be added in the formatting.php file under wp-includes folder.
A sample encryption and decryption function can be accessed at Line 72 onwards at https://github.com/ray-ang/open-nis-patient-care-summary/blob/master/functions.php
