This applet uses the latest cryptography API available in JAVA, it's safe and no informations are transmitted outside the client JVM.
I developed this applet to access my sensitive personal data from all over around the world, even using an Internet cafè computer.
So how can you safely get your passwords from everywhere you are?
1) Crypt your document using the applet
2) Upload the crypted document somewhere in the web
... from an Internet cafè ...
3) Copy the encrypted document text and paste to the applet
...but honestly it's very likely I'm the only user of this applet... :)
