      Certificate Transparency

      Introduction

      HTTPS connections use cryptographic functions to provide confidentiality and integrity. It can provide features like domain validation, end-to-end encryption, and a trust chain from certificate authorities down to the end-user. Any flaws can endanger these goals, like the impersonation of a system, man-in-the-middle (MitM) attacks, and website spoofing. This project helps to find flaws and improve the overall security of our internet.
