There has been some solutions about keeping personal informations of your iPhone from the App Store, but those solution could refuse jailbroken iPhone. Thanks to Folks over iJailbreak, they have just introduced two methods for encrypting your personal information and messages with Cydia apps: Crypt 2.0 and its counterpart Decrypt 2.0.

One of the benefits of Crypt 2.0 is that it can be used anywhere, not just in a dedicated app.

The encryption plugins work anywhere you can enter text. All you need to do is type in your message and highlight it, use the context menu (by default used for copy and paste), and select the option for Crypt 2.0. The program will ask you to remember the encryption key and will spit out a string of numbers. To turn the numbers back into text, highlight the message, activate Decrypt 2.0 from the context menu, and you’ll see the translated message in a dialog box.

The encryption keys are pretty simple, usually a value like “550″, which will be easy to remember and use, but I’m guessing will be less powerful than the military-grade encryption that other services offer (including services in the app store). Just a tip: you probably don’t want to send the encryption keys through the same channel you’re sending encrypted messages from.

You might be better off with an encryption scheme that takes more than a thousand guesses to crack.

Both plugins can be found in the BigBoss repository. Crypt 2.0 is a paid plugin, available for $1, while the decrypt plugin is free. That said, you might be better off duping Foxygram (freemium) into thinking your iPhone, iPad, or iPod Touch isn’t jailbroken with xCon (a free circumvention tweak). The encryption should be far stronger, to the point where MIT’s Technology Review fears it could lead to a future of untraceable criminal activity. But if you’re just trying to keep noisy friends from snooping around in your diary, Crypt 2.0 should provide more than enough cryptographical muscle.
