CURLOPT_CAINFO_BLOB - Online Linux Manual PageSection : 3
Updated : January 09, 2022
Source : libcurl 7.82.0
Note : curl_easy_setopt options
NAMECURLOPT_CAINFO_BLOB − Certificate Authority (CA) bundle in PEM format
SYNOPSIS#include <curl/curl.h>
CURLcode curl_easy_setopt(CURL *handle, CURLOPT_CAINFO_BLOB,
struct curl_blob *stblob);
DESCRIPTIONPass 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 CURLOPT_SSL_VERIFYPEER(3) is zero and you avoid verifying the server's certificate, CURLOPT_CAINFO_BLOB(3) is not needed. This option overrides CURLOPT_CAINFO(3).
DEFAULTNULL
PROTOCOLSAll TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc.
EXAMPLEchar *strpem; /* strpem must point to a PEM string */
CURL *curl = curl_easy_init();
if(curl) {
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);
ret = curl_easy_perform(curl);
curl_easy_cleanup(curl);
}
AVAILABILITYAdded in 7.77.0. This option is supported by the BearSSL (since 7.79.0), mbedTLS (since 7.81.0), rustls (since 7.82.0), OpenSSL, Secure Transport and Schannel backends.
RETURN VALUEReturns CURLE_OK if the option is supported, CURLE_UNKNOWN_OPTION if not, or CURLE_OUT_OF_MEMORY if there was insufficient heap space.
