CyberChef is really useful, and it runs locally, so you never have to send your sensitive data to some random server anymore. The “recipes” feature is quite powerful, too, but I think my favorite thing about it is that I can often just paste random data in and run the “Magic” script and it’ll try to guess the data format for me.

I love how you can build complex operations from each of the simple primitives like From Hex->Uppercase->XOR->Remove NULL->To Hex and save them as a recipe. It reminds me of the Linux command line where each program is simple but you can pipe the output of one into another to create a chain that can perform complex data processing.

I never realized it was a UK governemnt agency developing this !

Yes. GCHQ is the signals intelligence agency that grew out of the work at Bletchley Park on code breaking in WW2. So the UK's version of the NSA.

I have no way of knowing either way. Or do I? I mean, how would you know? I really don't though. At least as far as you know.

Only if they know Visual Basic.

Well, this is a GUI, so it stands to reason that they're experts in Visual Basic.

> you never have to send your sensitive data to some random server anymore

If you live in the UK you are already sending one entire month of your full personal communications, and three months of your communications metadata, to this government organisation. Pardon the off-topic rant.
