I've been looking into making a completely private Wordpress blog and have found useful blogs/tutorials along the way that have helped such as David Hewsons pretty detailed walkthrough.
I currently have a system in place (online) that is nice and private and requires login credentials to access the blog, now here-in lies the problem. I'm worried that if my web server is hacked in some way (I'm not going to be ignorant to the fact that this may occur) and my database accessed then all of my posts will be viewable - thus defeating all of the front-end privation work.
I've looked for pre-built solutions to encrypt the posts themselves but nothing exists yet, what I need is a helping hand in the right direction for writing a Wordpress plugin as I haven't a clue where to start in relation to coding plugins in Wordpress, any help/tutorial links would be appreciated.
I do have quite extensive knowledge of PHP/MySQL albeit not in the Wordpress fashion of API's etc.
