Secure enough that encryption and decryption using javascript

Question

this is javascript library: jsencryption.js

I want to use it for:

• Encrypt user data on my site, and then send it to the database server.
• send the encrypted data from the database to the client browser, the user will put keyand

then show the source data.

3. The database does not save the key, therefore it is more secure.

I want to know how safe or insufficient it is, and what about http://www.passpack.com/en/home/

and How passpack.comto save a password.

thank
