The mathematics may be sound. But one question remains: <strong>why should you believe the key belongs to that server?</strong></p> <p>An attacker can generate a convincing key pair too. If your browser accepts whichever public key arrives first, encryption may protect the conversation beautifully—between you and the attacker.</p> <p>Public key infrastructure, or PKI, exists to solve that identity problem at scale. It combines public-key cryptography with certificates, trusted authorities, policies, repositories, and lifecycle controls. The result is not blind trust in a key. It is a repeatable way to decide whether a key is acceptable for a particular identity and purpose.</p>
