HTTP Public Key Pinning (HPKP) is a security mechanism that allows HTTPS websites to protect against impersonation by attackers using fraudulent digital certificates. It works by delivering a set of public key hashes to the client, which must appear in the certificate chain of future connections to the same domain. However, due to its complexity and potential for misuse, browsers deprecated and removed HPKP support in 2017 in favor of Certificate Transparency.
