Visit https://gchq.github.io/CyberChef and try this: U U D D L R L R B A

I'm annoyed my mouse cursor also didn't get the same effect...

By the way, lots of websites use this shortcut for fun stuff (my own applications usually open the internal dev tools when you use it, at least for desktop/frontend applications), so you should randomly try it from time to time :)

What do you mean by "try this"? Is "U U D D L R L R B A" some kind of shortcut combination?

It is the Konami code.

Ha, that is a fun Easter egg :)

Check the console for another one.

It doesn't seem to work for me?

Don't use the letters, use your arrow keys to represent (U)p, (D)own, (L)eft, (R)ight and 'B' and 'A' respectively. e.g. ↑↑↓↓←→←→ B A

Love it. Lots of websites intermittently have included it to add some fun to the site. [0].

Ha ha, great one. Thank you.

I’ve used this a lot and it’s very helpful; way easier than looking up random converters online that may or may not be what I want, or figuring out what the terminal command for what I want is (if there is one)

One of my most-used web-based tools. Down the bottom of the list are a lot of very useful generic file/media/string conversion tools too.

Actual website: https://gchq.github.io/CyberChef

That's the hosted web app. If you download the distribution, you can run it locally.

Open the web inspector in the app and note the console log if you want to start on a very elaborate and long easter egg hunt.

How long? I've rushed through to #12 and it seems still simple. (You do always the same things up until now).

But how many "challenges" are there?

I don't want to spent the whole day decoding files even it seems kind of funny.

Besides that, really great tool! Didn't know about it until now.

Hah, I've reached 12 too and I'm currently stuck there with no idea how to move forward....

Shame it doesn't change URL for different tools, would be useful for bookmarking

It should be set up to change the URL hash field with each different recipe you create. For instance, the URL for 'From_Base64' is:

https://gchq.github.io/CyberChef/#recipe=From_Base64('A-Za-z...

Let us know if it's not working on your device, :)

Cheers brother

Bookmarks are supported, but they work with input and recipe. I.E.:

https://gchq.github.io/CyberChef/#recipe=To_Base64('A-Za-z0-...

A use case could be to build a recipe to encrypt a message with your public key. Post the link on your website, now anyone can click the link and encrypt a message to you.

Becareful with that approach. I saw a company that used the QR generator function to setup MFA/TOTP codes on phones. I filed a bug since they were sending the TOTP seeds to a third party. It's a little silly in this case, since cyberchef is open source and the seed shouldn't leave the browser, but it's still a third party and it's easy to generate the codes in your own page.

I was expecting some food ; (
