| 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. |
| |
| If curl is built against OpenSSL library, and the engine pkcs11 is available, |
| then a PKCS#11 URI (RFC 7512) can be used to specify a certificate located in |
| a PKCS#11 device. A string beginning with "pkcs11:" will be interpreted as a |
| PKCS#11 URI. If a PKCS#11 URI is provided, then the --engine option will be set |
| as "pkcs11" if none was provided and the --cert-type option will be set as |
| "ENG" if none was provided. |
| |
| (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. |
| |
| (Schannel only) Client certificates must be specified by a path |
| expression to a certificate store. (Loading PFX is not supported; you can |
| import it to a store first). You can use |
| "<store location>\\<store name>\\<thumbprint>" to refer to a certificate |
| in the system certificates store, for example, |
| "CurrentUser\\MY\\934a7ac6f8a5d579285a74fa61e19f23ddfe8d7a". Thumbprint is |
| usually a SHA-1 hex string which you can see in certificate details. Following |
| store locations are supported: CurrentUser, LocalMachine, CurrentService, |
| Services, CurrentUserGroupPolicy, LocalMachineGroupPolicy, |
| LocalMachineEnterprise. |
| |
| If this option is used several times, the last one will be used. |
