rot13 Text Area encryption


v0.0.1 What it does: Encrypts the contents of a text box using rot13 cipher when you click on the "e13" button next to the textbox. See the example below.
Click on the e13 button

Why was this created?
Many a times, I have encoded contents of some textbox on sites like orkut.com just to attain some privacy and some fun. I used to do this using a C program.
So, this Greasemonkey script makes life easier for those who want to use the cipher frequently by allowing easy access within the browser.
Why rot13?
rot 13 is symmetric, which means that encryption and decryption can be done by the same algorithm!
Does it work?
Tested on many sites and works well!
