Sony's recent security "holes" showed how unsafe it can be to store data unencrypted. As some of you may know, I 'm working on re-releasing the free CRM theme Driftwood.

What is the most secure way to store sensitive (ie non-public information) post meta in the database?

  • Could you be more specific about the type of data stored? – mfields Jun 23 '11 at 15:36
  • It could be email, phone numbers, or in some cases social security numbers. The new system allows for the site admin to store any text/media they want about/for a contact. – m-torin Jun 23 '11 at 15:41

Use bcrypt.


  • Any good resources for how to do this in php or better yet hooking into WordPress? – mfields Jun 23 '11 at 16:01
