.SH DESCRIPTION
|
|
|
|
Pass a pointer to a null\-terminated string as parameter. The string should be
|
|
|
|
the format of your private key. Supported formats are "PEM", "DER" and "ENG".
|
|
|
|
|
|
|
|
The format "ENG" enables you to load the private key from a crypto engine. In
|
|
|
|
this case \fICURLOPT_SSLKEY(3)\fP is used as an identifier passed to the engine. You
|
|
|
|
have to set the crypto engine with \fICURLOPT_SSLENGINE(3)\fP. "DER" format key file
|
|
|
|
currently does not work because of a bug in OpenSSL.
|
|
|
|
|
|
|
|
The application does not have to keep the string around after setting this
|
|
|
|
option.
|
|
|
|
.SH DEFAULT
|
|
|
|
\&"PEM"
|
|
|
|
.SH PROTOCOLS
|
|
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
