An interactive intro to Elliptic Curve Cryptography
Summary
An interactive introduction to Elliptic Curve Cryptography explains how public-key cryptography works and why elliptic curves offer similar security with smaller keys. It walks through the math of points on curves, finite-field arithmetic, and the double-and-add algorithm, then demonstrates practical protocols like ECDH, ECDSA, and ECIES, and discusses curve choices and quantum threats. The piece emphasizes the security and efficiency benefits of ECC for modern IT systems.
