Encrypt and decrypt messages

 
How to use:
  1. paste or type the text you want to encrypt into the large input field.
  2. Then enter a keyword.
  3. Press the encrypt button and
  4. Copy the encrypted text into an email or chat or wherever.

Be sure to give the keyword to the recipient so that they can decrypt the text. I suggest to use a safer way than email to deliver the keyword (chat, txt, voice maybe). To decrypt a text use the same way and press the decrypt button. None of the data you enter is saved or even being sent to the server, the encryption happens in your browser (via JavaScript).
