So the Dutch intelligence agency has posted a Christmas Puzzel.
It’s related to cryptography and steganography mainly.
The puzzel is in dutch, but I think a lot of them can be made by English people as well.
You can find the puzzel here:
So I did the first 2 and I think googling the Dutch version of some words having to do with the theme ‘Christmas’ might help the English people trying this.
I’d say it being a foreign language makes it a bigger challenge.
There is no guide besides what’s in the file.
