.TH CURLOPT_CAINFO_BLOB 3 "31 March 2021" libcurl libcurl
|
|
.SH NAME
|
|
CURLOPT_CAINFO_BLOB \- Certificate Authority (CA) bundle in PEM format
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAINFO_BLOB,
|
|
struct curl_blob *stblob);
|
|
.fi
|
|
.SH DESCRIPTION
|
|
Pass a pointer to a curl_blob structure, which contains information (pointer
|
|
and size) about a memory block with binary data of PEM encoded content holding
|
|
one or more certificates to verify the HTTPS server with.
|
|
|
|
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.
|
|
|
|
If \fICURLOPT_SSL_VERIFYPEER(3)\fP is zero and you avoid verifying the
|
|
server's certificate, \fICURLOPT_CAINFO_BLOB(3)\fP is not needed.
|
|
|
|
This option overrides \fICURLOPT_CAINFO(3)\fP.
|
|
.SH DEFAULT
|
|
NULL
|
|
.SH PROTOCOLS
|
|
All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
|
|
.SH EXAMPLE
|
|
.nf
|
|
#include <string.h>
|
|
|
|
int main(void)
|
|
{
|
|
char *strpem; /* strpem must point to a PEM string */
|
|
CURL *curl = curl_easy_init();
|
|
if(curl) {
|
|
CURLcode res;
|
|
struct curl_blob blob;
|
|
curl_easy_setopt(curl, CURLOPT_URL, "https://example.com/");
|
|
blob.data = strpem;
|
|
blob.len = strlen(strpem);
|
|
blob.flags = CURL_BLOB_COPY;
|
|
curl_easy_setopt(curl, CURLOPT_CAINFO_BLOB, &blob);
|
|
res = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
