| .TH CURLOPT_SSLCERT_BLOB 3 "November 04, 2020" "libcurl 7.78.0" "curl_easy_setopt options" |
| |
| .SH NAME |
| CURLOPT_SSLCERT_BLOB \- SSL client certificate from memory blob |
| .SH SYNOPSIS |
| #include <curl/curl.h> |
| |
| CURLcode curl_easy_setopt(CURL *handle, CURLOPT_SSLCERT_BLOB, struct curl_blob *stblob); |
| .SH 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 string "P12" or |
| "PEM" must be specified with \fICURLOPT_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_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 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"); |
| 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. |
| .SH "SEE ALSO" |
| .BR CURLOPT_SSLCERTTYPE "(3), " CURLOPT_SSLKEY "(3), " |
