= HPKP: Public Key Pinning Extension for HTTP =
See [[http://tools.ietf.org/html/rfc7469 RFC7469]].
HPKP is an ' ''experimental''' HTTP header sent by a server to a client, to indicate that some certificates related to the site should be pinned in the client. The client would thus refuse to establish a connection to the server if the pining does not comply.
Due to its experimental nature, HPKP is currently '''not''' recommended on production sites. More informations can be found on the [[https://developer.mozilla.org/en-US/docs/Web/Security/Public_Key_Pinning MDN description page]].
