The string should be +the file name of your pinned public key. The format expected is "PEM" or "DER". + +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. +.SH DEFAULT +NULL +.SH PROTOCOLS +All TLS based protocols: HTTPS, FTPS, IMAPS, POP3, SMTPS etc. +.SH EXAMPLE +.nf +CURL *curl = curl_easy_init(); +if(curl) { + curl_easy_setopt(curl, CURLOPT_URL, "https://example.com"); + curl_easy_setopt(curl, CURLOPT_PINNEDPUBLICKEY, "/etc/publickey.der"); + + /* Perform the request */ + curl_easy_perform(curl); +} +.fi +.SH PUBLIC KEY EXTRACTION +If you do not have the server's public key file you can extract it from the +server's certificate. +.nf +openssl x509 -in www.test.com.pem -pubkey -noout > www.test.com.pubkey.pem +.fi +The public key is output in PEM format and contains a header, base64 data and a +footer: +.nf +-----BEGIN PUBLIC KEY----- +[BASE 64 DATA] +-----END PUBLIC KEY----- +.fi +.SH AVAILABILITY +Added in 7.39.0 for OpenSSL, GnuTLS and GSKit.
