CURLOPT_SSLCERT_BLOB(3) Library Functions Manual CURLOPT_SSLCERT_BLOB(3)
NAME
CURLOPT_SSLCERT_BLOB - SSL client certificate from memory blob
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLCERT_BLOB,
struct curl_blob *stblob);
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 CURLOPT_SSLCERTTYPE(3).
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 CURLOPT_SSLCERT(3) which instead
expects a filename as input.
DEFAULT
NULL
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
EXAMPLE
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);
}
}
AVAILABILITY
Added in 7.71.0. This option is supported by the OpenSSL, Secure
Transport, Schannel and mbedTLS (since 7.78.0) backends.
RETURN VALUE
Returns CURLE_OK if TLS enabled, CURLE_UNKNOWN_OPTION if not, or
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
