| 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. |
