.SH NAME
|
|
CURLOPT_ISSUERCERT_BLOB \- issuer SSL certificate from memory blob
|
|
.SH SYNOPSIS
|
|
.nf
|
|
#include <curl/curl.h>
|
|
|
|
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_ISSUERCERT_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 a CA certificate in PEM
|
|
format. If the option is set, an additional check against the peer certificate
|
|
is performed to verify the issuer is indeed the one associated with the
|
|
certificate provided by the option. This additional check is useful in
|
|
multi\-level PKI where one needs to enforce that the peer certificate is from a
|
|
specific branch of the tree.
|
|
|
|
This option should be used in combination with the
|
|
\fICURLOPT_SSL_VERIFYPEER(3)\fP option. Otherwise, the result of the check is
|
|
not considered as failure.
|
|
|
|
A specific error code (CURLE_SSL_ISSUER_ERROR) is defined with the option,
|
|
which is returned if the setup of the SSL/TLS session has failed due to a
|
|
mismatch with the issuer of peer certificate (\fICURLOPT_SSL_VERIFYPEER(3)\fP
|
|
has to be set too for the check to fail).
|
|
|
|
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_ISSUERCERT(3)\fP which instead
|
|
expects a filename as input.
|
|
.SH DEFAULT
|
|
NULL
|
|
.SH PROTOCOLS
|
|
All TLS\-based protocols

.SH EXAMPLE
|
|
.nf
|
|
|
|
extern char *certificateData;
|
|
extern size_t filesize;
|
|
|
|
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_ISSUERCERT_BLOB, &blob);
|
|
res = curl_easy_perform(curl);
|
|
curl_easy_cleanup(curl);
|

Added in 7.71.0. This option is supported by the OpenSSL backends.
|
|
.SH RETURN VALUE
|
|
Returns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or
|
|
CURLE_OUT_OF_MEMORY if there was insufficient heap space.
