CURLOPT_SSLKEY_BLOB - private key for client cert from memory blob
#include <curl/curl.h> CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLKEY_BLOB, struct curl_blob *blob);
CURLOPT_SSLKEY_BLOB(3) curl_easy_setopt options 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.
