title: Simple JavaScript encryption & decryption without using key
body: <p>I would like to know if it is possible to encrypt and decrypt a text, using pure JavaScript. <strong>I don't want to use a key</strong>. It may be an entry lever solution. But I simply want to encode a text "my-name-1" into some text format and want to retrieve the text from it. Is this possible, <strong>without using any js libraries</strong>?</p>
