Now open the encryptor-decryptor, and enter the key based on your bot, cipher text the one I gave in the message that has a header of ##### Encrypted: decrypt with http://www.fourmilab.ch/javascrypt/, and press decrypt.
While an encryption program such as JavaScrypt protects your message from being read by those not in possession of the key, sometimes you wish to obscure the very fact you're sending an encrypted message at all.
An encoded message just screams you're using encryption, which may attract unwanted attention to your activities even if snoopers cannot read the text of your messages.
Steganography attempts to conceal the presence of an encrypted message; over history a wide variety of techniques have been used:
secret compartments in objects, invisible ink, microdots, grilles used to hide letters of a message among innocent text, and, in the digital age, embedding messages as imperceptible noise in images and audio files.
