I'm studying cryptography and creating a website with resources to help people learn about digital signatures and encryption. I'm looking for like-minded people who are interested in this area. I need support. 1) My mathematical abilities are insufficient. I may make annoying mistakes. 2) Some things have become obvious to me, and my explanations are no longer sufficient. I'm sure this is the most pressing issue in our world. If you relate to this, please join me.
