shrib it up!

Here's another treat for the ubiquitous internet user: you can now lock your notes! This new feature widens the range of applications for this web tool.

Locking your notes provides you with the following benefits:

• your notes are encrypted with the AES CBC algorithm. The encryption code is not only open source, but can actually be looked at right in your browser by viewing the page source code - it is entirely written in Javascript.
• depending on the length of your password, it can take someone else up to years to unlock your text
• neither your password nor your text content are visible to anyone outside your PC. The password as well as your (readable) text only exist in your PC's memory. The only thing transmitted over the internet to save is the locked (encrypted) text.

Please note:

• the locking feature is only available in Javascript-enabled browsers. Specifically, notes saved with a Javascript-enabled browser will never be readable with a browser without Javascript support!
• All previously available features are still Javascript-independent.
• Remember your password! Losing your password is equivalent to losing your data.
• This website is still just a non-profit personal website, so use this service at your own risk. No guarantees are given on anything. Especially:
• Note that the above claims become invalid if your browser or PC is altered in any adverse way. E.g., if you have a key logger, root kit, manipulated browser, other concurrently open malicious javascript pages, or other malicious software on the PC you are using, your "secrets" may become compromised. However, the data sent to the shrib.com server is encrypted and as safe as the strength of your password.

I pride myself to have incorporated this very powerful feature into this tool in a very sleek way, but all respect and honor should go to John Walker who has brought us JavaScrypt, the basis of this implementation!

Thank you John.

More thanks for personal advice and enlightenment go to the crypto masters Dominik Raub and Ueli Maurer at the ETH in Zurich. Thank you for patiently explaining the bare minimum about symmetric encryption to the layman!

And by the way: I also changed the layout a bit, with the intention to improve it.

Please make comments, send me your feedback, and shrib away!
