+Tells curl to use the specified client certificate file when getting a file
+with HTTPS, FTPS or another SSL-based protocol. The certificate must be in
+PKCS#12 format if using Secure Transport, or PEM format if using any other
+engine.  If the optional password isn't specified, it will be queried for on
+the terminal. Note that this option assumes a \&"certificate" file that is the
+private key and the client certificate concatenated! See --cert and --key to
+specify them independently.
+
+If curl is built against the NSS SSL library then this option can tell
+curl the nickname of the certificate to use within the NSS database defined
+by the environment variable SSL_DIR (or by default /etc/pki/nssdb). If the
+NSS PEM PKCS#11 module (libnsspem.so) is available then PEM files may be
+loaded. If you want to use a file from the current directory, please precede
+it with "./" prefix, in order to avoid confusion with a nickname.  If the
+nickname contains ":", it needs to be preceded by "\\" so that it is not
+recognized as password delimiter.  If the nickname contains "\\", it needs to
+be escaped as "\\\\" so that it is not recognized as an escape character.
+
+(iOS and macOS only) If curl is built against Secure Transport, then the
+certificate string can either be the name of a certificate/private key in the
+system or user keychain, or the path to a PKCS#12-encoded certificate and
+private key. If you want to use a file from the current directory, please
+precede it with "./" prefix, in order to avoid confusion with a nickname.
+
+If this option is used several times, the last one will be used.
