+# NAME
+
+CURLOPT_SSLKEY_BLOB - private key for client cert from memory blob
+
+# SYNOPSIS
+
+~~~c
+#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 format (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
+filename as input.
+
+# DEFAULT
+
+NULL

+# %PROTOCOLS%
+
+# EXAMPLE
+
+~~~c
+
+extern char *certificateData; /* point to cert */
+extern size_t filesize; /* size of cert */
+
+extern char *privateKeyData; /* point to key */
+extern size_t privateKeySize; /* size of key */
+
+int main(void)
+{
+  CURL *curl = curl_easy_init();
+  if(curl) {
+    CURLcode res;
+    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");
+    res = curl_easy_perform(curl);
+    curl_easy_cleanup(curl);
+  }
+}
+~~~
+
+# %AVAILABILITY%
+
+# RETURN VALUE
+
+curl_easy_setopt(3) returns a CURLcode indicating success or error.
+
+CURLE_OK (0) means everything was OK, non-zero means an error occurred, see
+libcurl-errors(3).
