Hello, I'm MrOllie. I wanted to let you know that one or more external links you added to Cryptanalysis have been removed because they seemed to be inappropriate for an encyclopedia. If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page, or take a look at our guidelines about links.  MrOllie (talk) 18:33, 13 July 2021 (UTC)
