Certificate Transparency is a security framework designed to improve the security of SSL/TLS certificates. It allows anyone to monitor and audit the issuance of certificates, ensuring that they are not misused or issued fraudulently. By logging certificates in public, tamper-proof logs, it helps maintain trust in the public key infrastructure. The main goal of Certificate Transparency is to prevent man-in-the-middle attacks and other security threats. When a certificate is issued, it is recorded in a log that can be accessed by anyone. This transparency helps website owners and users verify the legitimacy of certificates, enhancing overall internet security.
