Certificate Transparency

Certificate Transparency (CT) is a security measure used to prevent malicious or misissued digital certificates for websites. It involves publicly logging all issued certificates in a transparent, tamper-proof record accessible to anyone. This allows domain owners and security researchers to monitor and verify that only legitimate certificates are issued for their sites. By making the issuance process transparent, CT helps detect and deter fraudulent certificates that could be used for impersonation or man-in-the-middle attacks, thereby enhancing trust and security in online communications.
