CURLOPT_SSLKEY_BLOB(3) libcurl CURLOPT_SSLKEY_BLOB(3)
NAME
CURLOPT_SSLKEY_BLOB - private key for client cert from memory blob
SYNOPSIS
#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLKEY_BLOB,
struct curl_blob *blob);
DESCRIPTION
Pass a pointer to a curl_blob structure, which contains information
(pointer and size) for a private key. Compatible with OpenSSL. The for-
mat (like "PEM") must be specified with CURLOPT_SSLKEYTYPE(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_SSLKEY(3) which instead
expects a file name as input.
DEFAULT
NULL
PROTOCOLS
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
EXAMPLE
CURL *curl = curl_easy_init();
if(curl) {
struct curl_blob blob;
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
blob.data = certificateData;
blob.len = filesize;
blob.flags = CURL_BLOB_COPY;
curl_easy_setopt(curl, CURLOPT_SSLCERT_BLOB, &blob);
curl_easy_setopt(curl, CURLOPT_SSLCERTTYPE, "PEM");
blob.data = privateKeyData;
blob.len = privateKeySize;
curl_easy_setopt(curl, CURLOPT_SSLKEY_BLOB, &blob);
curl_easy_setopt(curl, CURLOPT_KEYPASSWD, "s3cret");
curl_easy_setopt(curl, CURLOPT_SSLKEYTYPE, "PEM");
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
AVAILABILITY
Added in 7.71.0. This option is supported by the OpenSSL 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.
