This online tool you can use to secure your online messages. As you can see below there is a password field, a message field and a output field. Just you need to write your message and enter your password. Then press the Encode button to generate the encrypted message. If anyone gets the encrypted message, she/he can not decrypt it until she/he gets the password. To decrypt the message just copy and paste the encoded message in the "Encoded Message" textbox and press the Decode button. Find the Demo below.
