Convert a message is a job description that involves encoding a message. Encoding is the process of transforming a message into a form that can be securely transmitted and decoded by the intended recipient. It is a way to protect the message from being read by unauthorized people. Encoding a message involves using a code or cipher to transform the original message into a form that is unreadable to anyone who does not have the key to decode it. This ensures that the message is secure and can only be read by the intended recipient.
