Did you know all messages sent via email are publicly accessible? In fact, your message can easily be intercepted while in transit, or it can be read as part of a normal text file by system administrators. Even worse, your message can legally be used against you shall you ever be on trial. To prevent eavesdroppers from reading your mail, you can encrypt it before sending the message. When the true recipient receives the email, he/she can decrypt the message, and read the messages as you sent it. This script does a pretty good job of encrypting messages, and any eavesdroppers will have an extremely difficult time deciphering the message without knowing your key.

To use this script, you first must come up with a key. Both you and the person you would like to contact should know this key. However, it is not recommended that you email the key, for an eavesdropper could intercept it very easily. Instead, we recommend that you tell the key to the recipient by another means, such as the telephone (although this is not entirely secure, either) or in person. Once you come up with a key, enter it into the "key" box below. Then, enter your message into the "message" box. Upon clicking on "Encrypt," the script will encipher your message in a unique way based on your key. The recipient should also type in the key, but place the encyphered message (ciphertext) into the "message" box. Upon clicking on "Decrypt," the decrypted (plaintext) message will be shown. The key to this encryption message is to keep your key private. Make sure no one knows your key besides yourself and anyone you send messages to. If you would like to automatically have the encyphered message sent to someone, enter both the recipient's email address and your email address in the boxes provided in the "Autosend Information" box.
