• I made a Caesar ciphered birthday greeting card for the daughter of a friend of mine, for her 10th birthday, along with a “key” made of two rotatable concentric paper strips with the alphabet on them. No instructions or anything. She deciphered it in like 30 minutes. She was super excited about it once she figured out what to do!

        Somehow one of the most fulfilling things I’ve done in years.

      Same, I love the idea of cryptography and breaking it but I’m not that good and don’t really have the time, so I dabble a bit and mostly enjoy from afar. I’ve made a few pen and paper ciphers but don’t know how to have anyone test them.

          Yeah I thought so, but I feel weird asking people to solve my random cipher (I feel like a Reddit sub had a rule against asking that). I don’t actually know if it’s good or bad or ridiculous. I barely know the terms. I will have to look around more I guess. I’m sure there people who are the opposite and want to break random ciphers.

      If you want to learn lock picking, get a job at an escape room. People destroy and abuse locks regularly and you’re expected to fix them or unlock them before the next person comes in. Also lockpickinglawyer
