# Bookmarklet

A bookmarklet is *a bookmark stored in a web browser that contains JavaScript commands that add new features to* the browser.

They are stored as the [URL](https://en.wikipedia.org/wiki/Uniform_Resource_Locator) of a bookmark in a [web browser](https://en.wikipedia.org/wiki/Web_browser) or as a [hyperlink](https://en.wikipedia.org/wiki/Hyperlink) on a [web page](https://en.wikipedia.org/wiki/Web_page). Bookmarklets are usually small snippets of [JavaScript](https://en.wikipedia.org/wiki/JavaScript) executed when the user clicks on them. When clicked, bookmarklets can perform a wide variety of operations, such as running a search query from selected text or extracting data from a table.

The code given here is a variation of the Vignere Cipher.

Upon clicking this bookmarklet, the code is copied.

I then simply run the code in the console to get flag.
