+Long: proxy-pinnedpubkey
+Arg: <hashes>
+Help: FILE/HASHES public key to verify proxy with
+Protocols: TLS
+---
+Tells curl to use the specified public key file (or hashes) to verify the
+proxy. This can be a path to a file which contains a single public key in PEM
+or DER format, or any number of base64 encoded sha256 hashes preceded by
+\'sha256//\' and separated by \';\'
+
+When negotiating a TLS or SSL connection, the server sends a certificate
+indicating its identity. A public key is extracted from this certificate and
+if it does not exactly match the public key provided to this option, curl will
+abort the connection before sending or receiving any data.
+
+If this option is used several times, the last one will be used.
