We need help with designing an encryption strategy for file and database storage. We propose using something similar to: http://stackoverflow.com/questions/18346054/how-does-megas-encryption-work-for-sharing To give you an understanding of our applications infrastructure: User A: Stores user file and database data User B and User A become friends and allow each other to share their file and database data. The encryptions will need to be END to END. ----- I propose: Symmetric Master Key and Private RSA Key encrypted using hash from user password, this will be stored in the central database so a user can login from another application and still access their data. User Files and DB data will be encrypted using a Symmetric session key. The session key will be encrypted using the owners Symmetric master key for use by the owner of the files and with the friends public RSA key for when sharing it with a friend. Encrypted Session keys are also stored in the database so they can be accessed by the same user on different clients. -------- We will also need a demo application created which shows encryption/decryption of files and string using the strategy.

Inside our clients Wordpress site they have things occurring that lead us to believe there is malware. This corrupt code keeps getting inserted inside the site, messing up the content management, and plugins cannot be added or updated. Due to potential malware on one of our sites we need to do a backup of our database, and wp-content folder. Then create a new Managed Wordpress site and do a manual migration to the new site with overriding the new database with our own, then overwrite the wp-content folder with our own. We need to ensure the core files of wordpress will be clean. The next step after doing that would be to get setup with Sitelock, or any other malware removal tool, to help clean out whatever may possibly be inside the database/content files (if any).
