Add Password-based Public-key Encryption to Drupal 8

The goal of this project is to provide a role-based data encryption feature for securely storing highly sensitive data in Drupal 8. Accordingly, ownCloud’s Data Encryption Model will be used in this project which is proven to be truly secure and highly scalable. An end-user will just enable this new encryption mechanism for the sensitive fields in his website. And then even in the case of a full database breach, he’ll have the surety that his sensitive data is still well protected.
