Wordpress encryption for HIPAA compliance

Hi,

I'm wondering to what extent encryption of parts of the wordpress database is possible. Any use of wordpress for medical/patient interaction will require any patient information to be encrypted (HIPAA compliance), and unfortunately I haven't come across a solution in my search so far.

For example, a patient's email address, physical address, name, time of appointment, messages (pretty much anything that could identify them) will need to be encrypted on the wordpress database. Then when the user logs in, decrypted and displayed. Is this possible?

I've come across the following on wordpress support:

Obviously a SSL certificate needs to also be in place, and while encryption won't stop someone from eventually getting the data, it offers the site owner legal protection. Any advice would be appreciated! Thanks
