|
|
.SH NAME
|
|
CURLOPT_SSLCERT_BLOB \- SSL client certificate from memory blob
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLCERT_BLOB,
|
|
struct curl_blob *stblob);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a curl_blob structure, which contains (pointer and size) a
|
|
client certificate. The format must be "P12" on Secure Transport or
|
|
Schannel. The format must be "P12" or "PEM" on OpenSSL. The format must be
|
|
\&"DER" or "PEM" on mbedTLS. The format must be specified with
|
|
\fICURLOPT_SSLCERTTYPE(3)\fP.
|
|
|
|
If the blob is initialized with the flags member of struct curl_blob set to
|
|
CURL_BLOB_COPY, the application does not have to keep the buffer around after
|
|
setting this.
|
|
|
|
This option is an alternative to \fICURLOPT_SSLCERT(3)\fP which instead
|
|
expects a filename as input.
|
|
.SH DEFAULT
|
|
NULL
|
|
.SH PROTOCOLS
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
|
|
|
This option works only with the following TLS backends:
|
|
OpenSSL, Schannel, Secure Transport and mbedTLS
|
|
.SH EXAMPLE
|
|
.nf
|
|
|
|
extern char *certificateData; /* point to data */
|
|
extern size_t filesize; /* size of data */
|
|
|
|
int main(void)
|
|
{
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode res;
|
|
struct curl_blob stblob;
|
|
stblob.data = certificateData;
|
|
stblob.len = filesize;
|
|
stblob.flags = CURL_BLOB_COPY;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
curl_easy_setopt(curl, CURLOPT_SSLCERT_BLOB, &stblob);
|
|
curl_easy_setopt(curl, CURLOPT_SSLCERTTYPE, "P12");
|
|
curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "s3cret");
|
|
res = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|
|
}
|
|
}
|
|
.fi
|
|
.SH AVAILABILITY
|
|
Added in 7.71.0. This option is supported by the OpenSSL, Secure Transport,
|
|
Schannel and mbedTLS (since 7.78.0) backends.
|
|
.SH RETURN VALUE
|
|
Returns CURLE_OK if TLS enabled, CURLE_UNKNOWN_OPTION if not, or
|
|
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
