Cryptdowner is a fun little project that encrypts a message and encodes it into the url. It allows for private sharing of information without the need for back end storage.

Try it here: cryptdowner

Usage

To use the app just enter a password and a message and hit the Encrypt button. The URL with the message will be copied automatically to your clipboard.

When you recieve a message, simply enter the URL into your browser and type the password you securely shared with the sender and hit the Decrypt button. If you have entered the correct password, the message will appear in the text field.
