Encrypted But Searchable Online Storage? 266
An anonymous reader asks "Is there a solution for online storage of encrypted data providing encrypted search and similar functions over the encrypted data? Is there an API/software/solution or even some online storage company providing this? I don't like Google understanding all my unencrypted data, but I like that Google can search them when they are unencrypted. So I would like to have both: the online storage provider does not understand my data, but he can still help me with searching in them, and doing other useful stuff. I mean: I send to the remote server encrypted data and later an encrypted query (the server cannot decipher them), and the server sends me back a chunk of my encrypted data stored there — the result of my encrypted query. Or I ask for the directory structure of my encrypted data (somehow stored in my data too — like in a tar archive), and the server sends it back, without knowing that this encrypted chunk is the directory structure. I googled for this and found some papers, however no software and no online service providing this yet." Can anyone point to an available implementation?

if the server cannot decipher the query it cannot execute it on a binary blob of encrypted data. FAIL.

...isn't this easy?
Plaintext: "Attack at dawn"
Ciphertext: "lkaoiuast98u;aw"
Search query: "oiua"
Result: "lkaoiuast98u;aw"
What could be simpler?
(no, I'm not an idiot, this is a joke.)

I prefer ROT26. It's got built-in steganography to boot.

Not good enough. The bartender could audit his liquor to see how much of each bottle was dispensed.
This is why when they do this sort of thing, the gentleman just serves the bartender a National Security Letter and takes more than what he wants without paying a dime.

Gee guys, isn't this a little bit too much work just to hide your porn?
Just mark the directory as hidden, your mom will not find it.

NOT TRUE! I use a combination of XOR and rot-13 encryption and I'm able to do text searches just fine. The trick is to encrypt the search string, then it'll work perfectly. This is because the encryption doesn't depend on the position within the text, but that shouldn't hurt security too much.

I tried the vi command, but I get this weird error:
'vi' is not recognized as an internal or external command,
operable program or batch file.
Does this mean ROT13 is not compatible with Windows?

It can't, that's why I use Live Search. It doesn't understand the query, the data, or the result. Unfortunately, for the OP, it doesn't support encryption.

I think so... perhaps you should try another operating system [gnu.org]?
Be aware though, it's got a weird text editor...
