Deep dive into Elliptic Curve Signatures
To popular demand, I have decided to try and explain how the ECDSA algorithm works. We've discussed a bit eliptic curve signatures before and a little bit more afte that , but it seems it's never enough. Admitedly, I've been struggling a bit to understand it properly and while I found a lot of documentation about it, I haven't really found any ECDSA for newbies anywhere. So I thought it would be good to explain in simple terms how it works so others can understand it better. Let's give it a stab ECDSA stands for Elliptic Curve Digital Signature Algorithm and it's used to create a digital signature of data (a file for example) in order to allow you to verify its authenticity, without compromising its security. Think of it like a real signature, you can recognize someone's signature, but you can't forge it without others knowing. The ECDSA algorithm is basically all about mathematics. But these maths are fairly complicated, so while I'l
