I’ve just made this easy to use data encryption tool. The encryption algorithm is taken from Rob Bovey’s site.

You can drop your data on to the worksheet (you can add extra worksheets too if you like) and then encrypt the data with the press of a button. You will be asked to provide a key, which you must remember. Save the file and send it out.

The receiver can then contact you for the key. When they click the decrypt button it will ask them for the key, if they enter it correctly it will return the original data. If they enter the wrong key the data will be encrypted again.

I have not tested this much, so make sure you back up your originals and remember there is not such thing a truly save data!

If you have any questions or suggestions drop me a comment.

Enjoy!
