+.TH CURLOPT_PROXY_SSLCERT_BLOB 3 "November 04, 2020" "libcurl 7.75.0" "curl_easy_setopt options"
+
+.SH NAME
+CURLOPT_PROXY_SSLCERT_BLOB \- SSL proxy client certificate from memory blob
+.SH SYNOPSIS
+#include <curl/curl.h>
+
+CURLcode curl_easy_setopt(CURL *handle, CURLOPT_PROXY_SSLCERT_BLOB, struct curl_blob *blob);
+.SH DESCRIPTION
+Pass a pointer to a curl_blob structure, which contains information (pointer
+and size) about a memory block with binary data of the certificate used to
+connect to the HTTPS proxy. The format must be "P12" on Secure Transport or
+Schannel. The format must be "P12" or "PEM" on OpenSSL.  The string "P12" or
+"PEM" must be specified with \fICURLOPT_PROXY_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_PROXY_SSLCERT(3)\fP which instead
+expects a file name as input.
+.SH DEFAULT
+NULL
+.SH PROTOCOLS
+All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
+.SH EXAMPLE
+.nf
+CURL *curl = curl_easy_init();
+if(curl) {
+  struct curl_blob blob;
+  blob.data = certificateData;
+  blob.len = filesize;
+  blob.flags = CURL_BLOB_COPY;
+  curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
+  curl_easy_setopt(curl, CURLOPT_PROXY, "https://proxy");
+  curl_easy_setopt(curl, CURLOPT_PROXY_SSLKEY, "key.pem");
+  curl_easy_setopt(curl, CURLOPT_PROXY_KEYPASSWD, "s3cret");
+  curl_easy_setopt(curl, CURLOPT_PROXY_SSLCERT_BLOB, &blob);
+  ret = curl_easy_perform(curl);
+  curl_easy_cleanup(curl);
+}
+.fi
+.SH AVAILABILITY
+Added in libcurl 7.71.0. This option is supported by the OpenSSL, Secure
+Transport and Schannel 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.
