Hiya People!
I have, for some time, had a specific problem in mind. I cannot, for the life of me, think of a better group to tell me my idea is crap.
In any case, I have a personal knowledge base I host facing the internet on a VPS. It is perfect for me, accessible, based on dokuwiki so its really easy to backup entire installation, the works. It is setup as a private wiki, so login is mandatory for viewing, editing, etc.
What I am looking for is mechanism for encrypting the data on the webserver when the user is not logged in. Under this scheme, the content of the server would be encrypted, only to be decrypted by the authorised password and encrypted again upon logout (or timeout).
Does this make sense? are there solutions like this out there?
I will attempt writing a plugin for dokuwiki, just wanted to make sure there is something out there that solves this problem in general.
Thank you!
If the attacker can attack your password hashes at full speed (they get access to the disk) then you would need a fairly hefty password or a random passphrase with a fair number of words in it. That fact can make the sort of protection you seem to be hoping for impractical in many cases.
Not sure I follow. What I am proposing is a way of encrypting the content of the website. Decrypted only while in use, this way, if someone gets access to the server (bug, leaked password, etc) the content is still encrypted.
